What is a CT Scan of the Chest?
Computed tomography (CT) scan (also known as CAT scan) of the chest is a painless radiology exam, which may be performed to examine the cause of pain in the chest area in a non-invasive manner. In the chest CAT scan, multiple images of the organs inside of the chest are generated. These images are more detailed than traditional x-rays.
The CT scan aids doctors in detecting inflammatory conditions, tumors, and evaluating other abnormalities such as lung disorders including cancer, pneumonia, pulmonary fibrosis, and tuberculosis. Sometimes doctors also recommend a chest MRI to verify the CT scan findings.
Who should get a Chest CT Scan?
CT scan of the chest is usually ordered by doctors, if you have any of the following indications:
- Masses, evaluation of nodules, cancer, or metastatic disease
- Obstructive processes
- Pulmonary embolism or dissection
How is the scan performed?
During the scan, a technologist will give you instructions such as ‘raise your arms above your head’ and ‘hold your breath for 10 to 12 seconds’.
If your doctor has ordered you to take a chest CT scan with contrast, then a contrast dye will be injected into your vein shortly before the scan begins.The dye will make your chest organs show up better in the test images.
What is the duration of the scan?
A CT scan of the chest is usually completed within 30 minutes. This includes 10 minutes for preparation and 15 to 20 minutes for the scan.
Is radiation involved in the scan?
Yes. CT scan is an imaging test, which involves a small amount of radiation to show pictures of the organs, tissues, and bones of the body.
