Throughout the world, lung cancer is the most commonly occurring form of cancer. A lung CT scan can detect the start of lung cancer in its earliest stages, allowing the disease to be treated before it has a chance to spread.
Our radiology services include the lung CT scan for early cancer detection and other pulmonary health issues. Your doctor may order a lung CT scan to:
- Find out the cause of shortness of breath or chest pain
- Determine whether you have a tumor, excess fluid around the lungs, or a pulmonary embolism (a blood clot in the lungs)
- Follow up on abnormal findings from standard chest X-rays
- Check for other conditions, such as tuberculosis, emphysema, and pneumonia
What happens during a lung CT scan?
The chest CT scanning machine takes many pictures, called slices, of the lungs and the inside of the chest. A computer processes these pictures to view on a screen or printed film. The computer also can stack the pictures to create a very detailed, 3D model.
Sometimes, a substance called contrast dye is injected into a vein in your arm for the CT scan. This substance highlights areas in your chest, which helps create clearer images.
Who should consider a lung scan?
Although lung cancer can occur in anyone, it is predominantly seen in former or current smokers, those who have been exposed to secondhand smoke, or those exposed to occupational hazards, such as toxic fumes or asbestos. People who have a family history of lung disease or are experiencing symptoms such as coughing, shortness of breath, wheezing or chest pain may also be candidates for this test.
