What does a CT scan with contrast of the lungs show?
A CT scan of the chest can help find problems such as infection, lung cancer, blocked blood flow in the lung (pulmonary embolism), and other lung problems. It also can be used to see if cancer has spread into the chest from another area of the body. A low-dose CT scan is a different type of chest CT scan.
Why would you have a CT scan with dye?

How long does a lung CT scan with contrast take?
How long will the CT Scan of the Chest with Contrast take? A CT scan of the chest with contrast takes about 40 minutes. This includes 20 minutes for the test and 20 minutes for preparation.
Why would a doctor order a CT scan of the chest with contrast?
Doctors use chest CT to: examine abnormalities found on chest x-rays. help diagnose the causes of signs or symptoms of chest disease, such as cough, shortness of breath, chest pain, or fever. detect and evaluate the extent of tumors that arise in the chest, or tumors that have spread there from other parts of the body.
Does a lung CT scan show COPD?
CT images can identify emphysema better and at an earlier stage than a chest x-ray. They can also identify other changes of COPD such as enlarged arteries in the lungs. CT is sometimes used to measure the extent of emphysema within the lungs.
Do you get CT scan results immediately?
CT Scan. CT Scans are one of the few tests where your doctor or radiology can receive test results nearly immediately. Your radiologists will review and interpret your CT scan as soon as it’s completed.
What organs does a chest CT scan show?
A chest CT (computed tomography) scan uses special X-ray equipment to take detailed images of the lungs, heart, blood vessels, airways, ribs and lymph nodes. Chest CT scans can help you doctor to determine the causes of chest symptoms such as cough, shortness of breath and chest pain.
How do you prepare for a lung CT scan?
If your doctor ordered a CT scan with contrast, do not eat anything three hours prior to your CT scan. You are encouraged to drink clear liquids.

What is a low-dose CT lung scan?
The radiation dose for CT lung screening is considered “low-dose” because the radiation exposure is less than a CT scan of the chest that’s done for a diagnosed medical problem. For more information on Lung CT please call, 404-778-2039 or complete the information request form below.
What are the risks of a CT scan of lungs?

What are the imaging methods used to examine the lungs?
Imaging methods to examine the lungs include chest X-ray, low-radiation-dose chest Computed Tomography (CT) and standard-radiation-dose chest CT. Low-radiation-dose CT is appropriate for cancer screening because it has been demonstrated to be more sensitive than X-ray in detecting cancer, with less radiation exposure than standard chest CT.
