Lung Scan Archives - Viascan of Las Colinas – Non-Invasive Preventative Body Scan and Screening Services


A CT (computed tomography) scan of the chest produces fine-grained pictures of the heart, blood arteries, ribs, airways, and lymph nodes using specialized X-ray equipment. Your doctor can identify the underlying causes of chest symptoms, including cough and chest discomfort, with the use of chest CT scans. CT scans of the chest can be used to identify lung illnesses, including early-stage lung cancer. A lung malignancy A CT scan may detect malignant growths with high accuracy.

However, because CT scans are so thorough, there is little chance that you will receive a false positive. As with mammograms, 12–14% of early lung cancer CT scans result in false positives. After the first scan, the false positive rate for CT scans decreases to 6%. Getting a CT scan for lung cancer is still the most effective strategy to avoid dying from the disease.

What is a lung cancer screening

When a person has a high chance of developing lung cancer but is otherwise healthy. Lung cancer screening is a procedure performed to find out whether lung cancer has already developed. For older persons who have smoked for a long period but do not exhibit any symptoms or indicators of lung cancer, screening for lung cancer is advised.

To check for lung cancer, medical professionals use a low-dose computerized tomography (LDCT) scan of the lungs. Treatment for lung cancer is more likely to be successful if it is found in its early stages. Talk to your doctor about the advantages and disadvantages of using lung scan for lung cancer screening. You can determine whether screening is suitable for you by cooperating.

Will a heart CT scan show lung cancer?

The amount and density of the mineral present in the blood capillaries supplying the heart’s arteries are rapidly and automatically measured by cardiac CT scans. One well-known indicator of the risk of coronary heart disease and stroke is coronary artery calcium. When the calcium score is zero, the risk of various illnesses is modest; when the score is greater than 400, the risk increases by about five times. Unfortunately, the precise prevalence of lung cancer at cardiac CT for lung cancer has not yet been thoroughly assessed.

This could be due to the small number of lung cancer cases that have been proven, as well as the fact that peripheral lung cancers. That are missed fall outside the cardiac field of view, making it impossible for studies that solely examined cardiac scans to measure what they were unable to see.

Can cancer be detected in a CT scan?

This might be the case because both scans are of the chest. Your doctor has to be aware of the precise organ or organs being examined, though. Your doctor might not even consider looking for lung cancer warning signals and might not order as thorough of a scan if they believed they were examining the arteries in your heart. Make sure you inform the Preventative Diagnostic Centre staff whether you would like to have a simultaneous scan of your heart and lungs. One way to cut expenses and radiation exposure is to combine a lung CT scan with a cardiac CT scan.

This is especially helpful for COPD patients who are more likely to have cardiac problems. But the reasoning applies to everyone who is worried about their heart and lungs. To put yourself at ease, a low-dose CT scan for lung cancer is a simple, non-invasive solution. If something is discovered, the test can be the one that saves your life.

Can a CT scan diagnose lung cancer?

A CT scan creates fine-grained cross-sectional pictures of your body using X-rays. Unlike a traditional X-ray, which only takes one or two images, a CT scanner collects numerous images. Which are then combined by a computer to display a portion of the body being examined. Lung tumors are more likely to be discovered by a CT scan than by standard chest X-rays.

It can also assist in identifying enlarged lymph nodes that may contain cancer that has spread, as well as the size, shape, and location of any lung tumors. This test can also be performed to search for tumors in other body sections. That may have spread from lung cancer.

Even while there are tests and gadgets that allow you to perform an at-home lung cancer test. They cannot diagnose or rule out lung cancer on their own. Discuss the findings with a physician or health care facility like Via Scan of Las Colinas, who can use them in conjunction with further diagnostic procedures like lung scans and a biopsy to aid in the diagnosis. The findings of these tests may only be interpreted and recommended courses of action by a physician.


One of the most common and lethal types of cancer, lung cancer, causes a significant number of cancer-related fatalities each year. Notwithstanding advancements in medical care, lung cancer is frequently detected at a stage where the illness has already spread and progressed. The absence of noticeable symptoms in the early stages of lung cancer is the cause of this delayed discovery. Most individuals are unaware that mild early symptoms, such as persistent cough or exhaustion, might be indicators of cancer.

What is Lung Cancer?

 The uncontrolled growth of cells in lung tissue indicates lung cancer. Usually, it begins as a tiny lung tumor that gradually enlarges over time to generate additional tumors that spread to other body areas. Lung cancer comes in two primary varieties: small cell and non-small cell. Although nonsmokers can also get lung cancer, smoking is the leading cause. Coughing, wheezing, chest discomfort, exhaustion, and weight loss are some symptoms. Although lung cancer is deadly in its advanced stages, it is frequently treatable if detected early through screening. The most remarkable results are obtained when the immunotherapy procedure, radiation therapy, chemotherapy, and surgery are paired with early discovery.

Do Lung Cancer Symptoms Come and Go?

Lung cancer symptoms might be difficult to identify; they frequently manifest slowly or come on and off.  Generally, people are concerned about the symptoms of such severe diseases, and the question of how I knew I had lung cancer is asked frequently. 

If you encounter any of these symptoms, which might include the following, you must exercise caution and consult with a medical expert.

  1. Chronic cough: A persistent cough lasting several weeks or months.
  2. Breathing difficulty that does not get better is known as shortness of breath.
  3. Chest Pain: Back, shoulder, or chest discomfort.
  4. Unexplained Weight Loss: Sudden weight loss without a discernible reason.
  5. Hemoptysis: coughing blood is a problematic symptom that must be treated immediately.
  6. Repeated Respiratory Infections: Frequent lung infections may be a sign.

Regular check-ups and lung cancer screenings are essential since early discovery can significantly improve prognosis.

What Does Lung Cancer Pain Feel Like?

Not everyone with lung cancer feels pain, and the intensity of discomfort varies from person to person. Usually, in the early stages, a patient may not feel intense pain but may feel tired.  When it does happen, it might show up as:

  • A dull ache is a low-level, chronic pain in the back, shoulders, or chest.
  • Sharp or Stabbing Pain: Abrupt, severe pain in the region of the ribs or chest.
  • Pain to the arms, neck, or jaw is radiating pain.
  • Pleural Pain: Pain resulting from inflammation of the lung lining or pleura.

It’s crucial to keep in mind that not every back or chest discomfort is indicative of lung cancer. Consult a healthcare expert for a thorough review if you have any concerns.

Does Lung Cancer Cause Chest Pain?

A significant issue for those concerned about lung cancer is chest discomfort. Chest discomfort can be caused by lung cancer, but it’s not necessarily the only cause. There are several possible causes of chest discomfort, such as:

Tumors: Chest discomfort may result from a tumor pressing on the chest wall.

Chest Infections: Lung ailments, such as pneumonia, a respiratory infection, can produce pain in the chest.

Swelling: Pleurisy, or inflammation of the pleura, can cause pain.

If you have chest discomfort, you must have regular checkups and examinations right away because several different medical disorders can cause it.

How I Found Out I Had Lung Cancer?

A lung cancer diagnosis can be an emotional roller coaster ride for many of us. The human body is designed in a way that it can communicate, but to know what is wrong, one must pay attention to even tiny indicators such as pain. Here, a question arises: “Can I detect serious medical conditions such as lung cancer?” The answer is yes. Even if one pays little attention to these signs, one might still know what is happening with their body. Taking proper care, being vigilant, and having regular checkups are the keys to a healthy life. Screening processes make things a lot easier in terms of the identification of anomalies. With precise and high-quality imaging, medical professionals can detect abnormalities at a very early stage. 

Lung Cancer Screening Centers.

Centers for lung cancer screenings, such as ViaScan, facilitate early detection, which is essential for better results. When lung cancer is still in its early stages and most curable, these specialist institutions use cutting-edge imaging technologies to identify it.

CT lung cancer screening scans are one kind of screening. This creates cross-sectional lung pictures with little radiation exposure using CT algorithms. Advance algorithms allow the radiologist to identify any anomalies in the organ. Radiologists review the scans to find cancers before they cause significant symptoms. 

Nuclear medicine lung scans are another method of diagnosis. This uses radioactive tracers that are administered intravenously to monitor blood flow in the lungs. Unusual tracer buildup identifies problem locations. Nuclear lung scans offer functional information to supplement CT’s anatomical imaging.

How is a Lung Scan Performed?

A lung scan is a screening process that involves taking images of the respiratory system and lungs using specialized equipment such as a CT scan machine. The key steps are as follows:

  1. To ensure that no metal items or clothing interferes with the procedure, the patient will be requested to change into a hospital gown.
  2. The technician will inquire about any allergies, medical problems, or medicines while explaining the process.
  3. On a table that slips inside the scanning device, the patient rests flat on their back. There could be a cushion available for comfort.
  4. The table is moved into the scanner, which does cross-sectional imaging while rotating in a spiral pattern around the chest. The patient needs to lie still.
  5. It takes 10 to 30 minutes to scan. To obtain clean scan pictures free of motion blur, patient participation is essential.
  6. Urine rapidly removes the radioactive tracer from the body following the scan. There is no need for recovery time or anesthesia.
  7. A radiologist then examines the lung pictures to look for anomalies such as inflammation, clots, infections, and lung cancer.

Final Thoughts

When discovered early, before it spreads outside of the lungs, lung cancer has a better prognosis and a higher possibility of effective treatment. Potential lung cancer signs, such as a chronic cough, chest discomfort, or unexplained weight loss, should be watched out for, and we should consult a doctor right away if any appear. As CT or nuclear lung scans can detect malignancies in their early stages, regular screening is advised for high-risk populations, such as smokers, even in the absence of symptoms. Increased screening knowledge and use can help detect lung cancer early while there is still hope for a cure. Lung cancer outcomes can be significantly impacted by being proactive and seeking rapid medical attention at the earliest indications.


What signs and symptoms of lung cancer are most typical?

A chronic cough, blood in the cough, wheezing, shortness of breath, chest discomfort, hoarseness, and unexplained weight loss are the most typical signs of lung cancer.

What is the cause of non-smoker lung cancer?

A genetic predisposition, asbestos exposure, radon gas exposure, or air pollution can all lead to lung cancer in nonsmokers.

Is it possible to treat lung cancer if detected early?

 It’s true that when lung cancer is discovered in stages 1 or 2 before it spreads, the survival percentage is significantly greater. The best outcomes come from early treatment with alternatives, including surgery, chemotherapy, radiation therapy, or targeted medication treatments.
