Purpose of the Test

A CT (computed tomography) scan of the neck and chest with contrast is typically ordered to evaluate the structures and tissues in the neck and chest region, such as the lymph nodes, thyroid gland, trachea, lungs, and blood vessels. It is commonly used to diagnose conditions such as tumors, infections, inflammation, and injuries in these areas.

When this test is required

The CT neck and chest with contrast is usually ordered by a physician or other healthcare provider when they suspect there may be a problem in the neck or chest that needs further evaluation. The test is usually performed in an outpatient setting, such as a radiology department or imaging center.

What the Test Detects

A CT neck and chest with contrast is a diagnostic medical imaging test that combines a computed tomography (CT) scan of the neck and chest with the use of a contrast dye. The contrast dye helps to highlight specific areas of the body and makes them more visible on the images produced by the CT scan.

Preparation for the Test

Before the test, you may be instructed to avoid eating or drinking for a certain period of time, especially if you will receive intravenous (IV) contrast material. You may also need to inform your doctor if you have any allergies or medical conditions, such as kidney disease or diabetes, that may affect the use of contrast material. It’s essential to follow the specific instructions provided by your doctor or radiology department to ensure accurate and safe testing.

Sample Requirements

The test requires a sample of your body tissue or fluids. Instead, it is a non-invasive imaging procedure that uses X-rays and contrast material to produce detailed images of the neck and chest region.

Additional Notes

Patients should inform their doctor if they have any allergies or kidney problems before undergoing the test, as the contrast dye can sometimes cause an allergic reaction or worsen kidney function in some individuals. Patients should also avoid eating or drinking anything for a few hours before the test, as this can interfere with the results.
