When a healthcare provider suggests a CT scan for diagnostic purposes, you might feel curious about it. It is completely common to have certain questions, such as what happens during a CT scan, whether it is risky, or whether it has any side effects. Knowing about the imaging process and how it works will make you feel more guided.

Let’s walk you through each step of the CT scan, from how it works to scan preparation to what happens during or after the procedure.  

What is a CT scan?

A computed tomography (CT) scan is a type of advanced imaging test used in medical terms to evaluate injuries and diagnose diseases. This scan utilises X-ray technology and advanced computers to create 3D images of various body parts from multiple angles. 

This will help your healthcare provider to see your internal structures, such as bones density scan, tissues, and blood vessels from multiple angles clearly. The scanning images are typically used to evaluate the progress of ongoing treatments, diagnose diseases, or detect certain infections, such as cancer.

How does imaging technology work?

The CT scanner is a large, doughnut-shaped machine with a moving bed attached to it that will go in and out while taking pictures. 

X-ray source 

While you are lying down on the table, the X-ray source will move around your body, sending radiation to your targeted body parts.

Detectors

Advanced detectors will detect the emitted radiation on the other side of the body. 

Computer processing 

The computer will collect the data and combine it to create a 3D image that your healthcare provider can see on the screen. You can see them later as well. 

This advanced, accurate, and precise technique will help doctors to see tiny fractures or early tumours before they spread. 

Why do I need a CT scan?

Your doctor might suggest a CT scan for various reasons, including:

  • Detect bone fractures 
  • Identify any early tumours or blood clots 
  • Detect blockages in blood vessels 
  • Diagnose infections and heart disease 
  • Monitor the progress of treatment 
  • Trace disease progression 

A CT scan is the most trusted choice in cases where healthcare providers need quick and clear answers. 

How do I prepare for the CT scan?

The scan preparation depends on the scan your doctors have suggested for you. Moreover, your doctor will explain everything you need to know, from how you need to prepare for the scan to what will happen during the procedure. Here are some guidelines:

  • You may be advised to stop eating or drinking a few hours before the scan. 
  • If you are allergic to any dye, chemical, or medication, you need to inform your doctor beforehand, and they will adjust your treatment accordingly. 
  • You must arrive early on the scan day to become familiar with the surroundings and remain calm. 
  • Remove all the jewellery before the scan, as any metallic object can distort the images, leading to inaccurate results.
  • It’s better to change into a hospital gown for a more comfortable journey.

Furthermore, if you have any questions or concerns, you can ask your doctor right away.

What should I expect during my CT scan?

  1. First, you will arrive at the facility, and your doctor will review all the instructions and re-explain the entire process to ensure there is no confusion.
  2. They will inject a contrast dye to make some structures more visible. It can be either injected into your blood or given orally, depending on the type of scan.
  3. You will be asked to lie on the bed.
  4.  The bed will go inside the scanner during the scan.
  5. Throughout this time, your doctor will monitor you, and you can even talk to your doctor. 
  6. When the bed begin to move inside the scanner, you will hear some whirring sound as well.
  7. During the scanning, you may be asked to stop breathing. This will be only for a few seconds.

The computer will collect all the images, and your doctor can now see them for diagnostic purposes. If you want, a board-certified radiologist can review the results and decide what’s next.

How long does a CT scan take?

The entire process is completed in under an hour, with most of the time spent preparing for the scan. The scan itself only takes 5 minutes.

Are there any risks of a CT scan?

Healthcare providers consider CT scans completely safe because they use low doses of radiation. However, if you have certain health concerns, you can talk to trained professionals for a clearer and better understanding. 

People often ask, “Can I get a CT scan while pregnant? Or does it have a side effect?” The scan usually doesn’t have side effects, but some might feel nauseous due to the dye; however, it is rare. Moreover, if you are pregnant and need to go through a scan, it is wise to consult with the doctor.

What-does-a-Colonoscopy-Show-1200x800.jpg
26/May/2025

When you hear the word colonoscopy, many people might chuckle a little nervously or end up feeling very stressed. It’s much like hearing you’re expecting house guests; however, these guests are doctors, and the mess you must clean is inside your colon.

But get this: colonoscopies do an impressive job of helping find out what’s wrong with your bowels. Imagine it’s a backstage look at your digestive system, with high-definition cameras and a doctor who’s good at exploring inside our bodies. But that’s not the only benefit! You won’t be conscious for the entire time your friends are having all the fun!

What Exactly Does a Colonoscopy Involve?

It’s almost like a mini, flexible camera attached to a narrow tube, happily exploring your intestine, shooting pictures and videos as it goes. A colonoscopy is basically a method of looking inside your large intestine and rectum with a colonoscope.

So why do you require a photoshoot inside your body?

  • The biggest area to deal with is screening for cancer. Many people 45 and older receive regular colonoscopies to catch colon cancer in its early stages.
  • If your persistent stomach pain is accompanied by changes in your bowel habits, unwanted weight loss, or blood in your stool, your doctor might decide to examine you using a camera.
  • If someone in your family has had colon cancer, you may need to start screenings sooner. Treat it as getting advanced warning from your family to watch out for yourself.
  • Regular screenings are needed if you’ve had previous polyps removed or if you have some digestive health conditions.

 You’ll be put under for the time it takes (about 30 to 60 minutes), so there is no discomfort involved. Think of it as sleeping through your doctor’s treatment.

What Exactly Do Doctors See Inside the Colon During a Colonoscopy?

Things become especially interesting at this point. Doctors use colonoscopy to obtain a detailed view of the lining of the colon. Look at what you should be looking for:

Polyps are little growths on the colon wall that appear as small mushrooms. Most don’t cause problems, but a few might transform into cancer. There is some good news here. Your doctor can take them out through the scope during the procedure.

Redness and swelling in specific spots can be a symptom of inflammatory bowel disease, ulcerative colitis or Crohn’s disease.

  • Circumstances in which the colon’s blood vessels are wider or twisted may lead to bleeding.
  • Diverticulosis refers to small pouches that sometimes develop in the colon wall. As we get older, such spots on the skin are typical and rarely cause issues.
  • The camera can identify both benign and cancerous growths called tumours, so problems can be addressed before they turn serious.
  • After surgery or inflammation, scar tissue sometimes appears and could cause difficulties.

It’s like setting up a security camera system inside your body – everything is detected.

Is it possible for a colonoscopy to locate colon cancer before it spreads?

Absolutely! Colonoscopies are especially powerful when used here. When tiny, harmless-appearing polyps develop, colon cancer may start in the colon and gradually change over 10-15 years. Problems such as cancer can be found early in a colonoscopy, making it simpler to treat.

The most amazing thing is that over 90% of people diagnosed early with colon tumors do well. That’s great to know! Research in the New England Journal of Medicine has found that colonoscopy screening reduces both the number of colon cancer cases and the death rate (Zauber et al., 2012).  

What It Means to Catch Cancer Early:

  • When found in Stages 0-1, the cancer is usually treatable by surgery alone.
  • Polyps with a chance of turning cancerous may be removed before they do so.
  • Critical Places – Need to be watched more carefully

Fixing security vulnerabilities is like catching a small leak in your roof so it doesn’t cause a big flood. It matters a lot if you notice symptoms early.

Does a Colonoscopy Reveal Issues Other Than Cancer?

You bet! People usually talk about cancer screening, but colonoscopies are preferred for many diagnostic jobs, just like the Swiss Army knife. They may also expose other aspects of our lives:

  • Crohn’s disease and ulcerative colitis are conditions from the IBD group in which the bowel swells and becomes inflamed.
  • If you have IBS, the colonoscopy allows your doctor to check for different conditions that have similar symptoms.
  • If blood is visible in your stool, a colonoscopy allows doctors to find the source of the bleeding.
  • Bacteria or parasites may lead to changes that become visible in the colon.
  • Structural Problems, such as twisting in the intestines, narrow spots, or anatomical obstacles, may be noticed as the procedure progresses.

It works a lot like a detailed home checkup, except for your digestive system. 

Could There Be Anything Important That a Colonoscopy Doesn’t Detect?

I’m letting you know upfront that colonoscopies are very detailed but not flawless. Before you get too stressed, let’s see where we stand.

The things we might not catch:

  • Any polyps that measure less than 5 millimeters
  • Lesions that are found tucked away in the folds of the colon
  • Sections that remain hidden because of poor casting
  • Polyps that are flat and don’t jut out

Yet, There’s No Need to Panic:

  • Today’s colonoscopes come with high-definition imaging technology
  • Experienced doctors have mastered every section of the body.
  • Getting set up for LPP ahead of time leads to fan interaction.
  • The bulk of the missed lesions are not major and are harmless to start with

What Should a Normal Colonoscopy Result Look Like?

A normal outcome for your colon is almost perfect on your report card. That’s usually what it refers to:

  • No Polyps Found – Your whole colon feels smooth and healthy with no abnormal clumps.
  • No signs of inflammation are noticed, and the tissue resembles pink, healthy tissue.
  • It All Looks Correctly Shaped and Placed.
  • Easy Trip – Your colonoscope made its way alongside the healthy and diseased areas of your colon.

Usually, once your screening colonoscopy is normal, you can wait 10 years before your next test. You might call it a hall pass from bowel pain for 10 years!

What Steps Should I Follow After Having a Colonoscopy?

The part everyone seems to want information on is the after-effects of a colonoscopy. Here’s what to focus on after your procedure:

Minutes and Hours Immediately After a Storm:

  • Just relax until the medication wears off.
  • Do not operate heavy machinery or make decisions for a while (as sedatives can cause you to be confused)
  • Make sure to eat foods that aren’t heavy and drink a lot of water.
  • It’s perfectly fine if you feel a bit bloated – you should expect that as you try your first fermented foods.

The first 24 to 48 hours are important.

  • After a short time, try eating your regular meals again.
  • Please don’t overdo it when you exercise.
  • Drink plenty of water to aid your body’s recovery
  • Stop and pay attention if you see signs of severe pain, fever or bleeding.

Keeping a few simple points in mind will help you recover properly from a colonoscopy.

  • Attend your next appointment so the doctor can explain your test results.
  • Ask for explanations when there are things you don’t understand
  • Stop any drugs your doctor suggested, as needed.
  • Remember that you made a great choice for your health!

Normally, people recover fully in only a day. Getting through colonoscopy recovery is generally much less difficult than the preparations you made before.

Are you also dreading the test that many people avoid: the colonoscopy? The moans of pain and protest are something I’m already used to hearing. However, what if you knew that this short nap of sedation could mean the difference between life and death? The doctor might learn the most about your health by checking your rear view.

While it might not be an ideal way to spend a day, learning what a colonoscopy can catch could motivate you to make that call and schedule the procedure. Let’s examine the various medical situations this behind-the-scenes work may uncover!

What Is a Colonoscopy? And Why Should Everyone Know It’s So Important?

Just like a photoshoot, a colonoscopy is designed to help find any issues in your colon. During this examination, a tiny camera on the colonoscope takes clear images of your colon’s inner walls.

A colonoscopy screening is like putting a security system into your body. Problems can often be found at the earliest stages, which is when treatment is least complicated. With colonoscopies, doctors can observe and manage any issues they see during the initial visit.

Could a Colonoscopy Spot Cancer in the Body Before It Develops?

Yes! This is why colonoscopies hold such value. What makes them special is their talent for noticing polyps that may be harmless at first but might eventually become cancerous.

Many times, a diagnostic colonoscopy finds potential problems, like polyps, in the colon long before they turn cancerous. Treat it to intercept an individual before they act on their crime! Cancer development is prevented because the polyps are removed during the procedure.

A study in the New England Journal of Medicine showed that having a colonoscopy and removing polyps can reduce deaths from colorectal cancer by almost 53% 

Can a Colonoscopy Find Specific Types of Cancer?

The top superstar in detection turns out to be colorectal cancer, as it is the third most common cancer for both men and women. However, this flexible screening measure offers more than just the specifics listed here.

Colonoscopy can detect a variety of illnesses.

  • All kinds of colon cancer, no matter what stage
  • Cancer that begins in the last sections of the colon is called rectal cancer.
  • Clues to anal cancer are usually uncommon.
  • There are times when cancer cells are found in the lymph nodes from other organs.

Suppose you get regular screenings at a well-known wellness screening centre. In that case, these cancers can sometimes be treated before they begin sending their unbidden invitations to other locations in your body.

What Other Serious Illnesses Can a Colonoscopy Catch?

Your colonoscopy is working hard. But it also helps detect other health concerns.

  • Crohn’s disease and ulcerative colitis, known as Inflammatory Bowel Disease (IBD), can cause inflammation, irritation and harm to the digestive tract.
  • Small outpouches that may develop in your colon and could become infected are known as diverticulosis and diverticulitis.
  • Intestinal Bleeding: Looking for what causes blood to be found where it shouldn’t
  • Bowel Obstructions refer to conditions where waste is obstructed from leaving the bowel.
  • Strictures: Widening of the colon that may lead to significant obstructions

Think about your colonoscopy as the best clue-solver that the other tests fail to unveil!

Can a Colonoscopy Help with the Diagnosis of Infections or Parasites?

Your colonoscopy can reveal any unwanted things in your colon! It is used to spot several infections and parasites that might be present.

  • C. difficile can cause inflammation by triggering bacterial infections.
  • Infections like Giardia or Entamoeba are known as parasites.
  • Pseudomembranous colitis is an inflammation that results from using some antibiotics.
  • CMV infections are found in the colon
  • Other tiny organisms can settle in your intestines.

Finding parasites can be crucial for anyone with mysterious digestive issues or for someone returning from an area where parasites are common.

Could It Help Reveal Why I Am Experiencing Digestive Troubles or Regular Bloating?

If you have been seeing several gastroenterologists but still don’t know what is wrong with your digestion, a diagnostic colonoscopy may provide answers.

It may reveal underlying issues that explain those troubling ailments.

  • Things that result in chronic diarrhoea or constipation
  • Possible explanations for constant stomach pain
  • Things that may lead to unexplained weight loss
  • Who could be responsible for painful bloating
  • Reasons for changes in bowel habits

Many find it comforting to finally get answers after years of experiencing unpleasant symptoms without much success in treatment. Sometimes, spotting the problem with early screening can make it apparent how to repair it.

Do I Need a Colonoscopy?

If you never felt the need, you might think that colonoscopies are unnecessary. The answer? I think it’s true.

There are substitutes, but colonoscopy is preferred for several reasons.

  • It helps you to see your colon from start to finish.
  • Your doctor will take steps quickly if something is discovered.
  • It provides the best and detailed results possible
  • If the screen is negative, you do not have to be tested for a while.

Would you prefer an in-depth checkup of your house that addresses all problems or a quick check where corners might be missed?

How Frequently Should I Go for a Colonoscopy?

Unless there are reasons to be more careful, typical folks should start screening every decade at age 45. It’s common for your timeline to be different because of:

  • In your family, there have been cases of colorectal cancer or polyps.
  • Irrational beliefs about the disease
  • Earlier colonoscopy findings
  • Diseases related to genes that raise the risk of cancer
  • Symptoms that doctors will investigate

If your doctor thinks you are at greater risk or if polyps or similar issues were found in your earlier screening, they may advise you to have more colonoscopies.
