Lung scans provided at Premier Diagnostic Imaging in Cookeville, Tennessee


All types of lung diseases combined form the third leading cause of death in the United States. Our 64-slice CT scanner can evaluate your lung health. Smoking and exposure to radon, asbestos, and air pollution are all causes of lung disease. If you already experience signs of unhealthy lungs, then you should discuss the symptoms with your doctor to determine if you should receive a Lung CT.


What is a Lung CT?

A Lung CT (Computed Tomography) combines special x-ray equipment with computers to create 64 cross-sectional pictures of your lungs. The photo quality is high enough to detect abnormalities and many lung diseases. Lung CT scans offer more detail than chest x-ray. Lung CTs give our radiologists a better view of your lungs to determine how healthy your lungs are.

Why would my doctor order a Lung CT?

Lung CTs help diagnose the causes of clinical signs or symptoms of disease of the chest, such as cough, shortness of breath, chest pain, or fever.

Lung CT can detect lung disorders including:

  • Benign and malignant tumors
  • Pneumonia
  • Tuberculosis
  • Bronchiectasis, cystic fibrosis
  • Inflammation or other diseases of the pleura (the covering of the lungs)
  • Interstitial and chronic lung disease
  • Congenital abnormalities

Can you detect cancer from a Lung CT?

CT technology is especially effective for diagnosing lung cancer at its earliest, most curable stage. Lung CT scans detect abnormal tissue, called pulmonary nodules. These nodules are often not cancerous. If your Lung CT results show the presence of pulmonary nodules, then you may be asked to return annually to ensure that the nodules don’t grow larger. Early detection of pulmonary nodules increases survival rates compared to those who do not receive Lung CT scans.

Smoking and Lung Cancer

A Lung CT is recommended yearly for individuals aged 55-80 who have a history of heavy smoking and either smoke now or have quit within the last 15 years. Heavy smoking means a smoking history of 30 pack years or more. 30 pack years means smoking a pack of cigarettes every day for 30 years, or the equivalent.

What to Expect

You will be comfortably positioned on a CT table, and you may be supported by pillows to help you stay in the proper position during the procedure. The table will move slowly into the opening of the CT scanner. Very small amounts of X-ray radiation will pass through your body. A CT examination usually takes between 15-30 minutes.

How to Prepare

Wear comfortable, loose-fitting clothing, without zippers or snaps. You may be asked not to eat or drink anything for up to 4 hours before the exam. Women should inform the technologist if there is any possibility that they are pregnant. Patient lockers are available for jewelry and other valuable items, however you are encouraged to leave all jewelry at home during procedures.


After your exam, your radiologist will review and interpret your Lung CT. Test results are available within 48 hours for you to view on our Patient Portal. We also send test results directly to your physician. From there, your doctor will follow up with you with the test results and recommendations regarding your lung health
