CT Skull Base With Contrast

Specimen Required

NONE

Fasting Required

Purpose of the Test

This test may be ordered to evaluate various conditions that affect the skull base, such as tumors, infections, or other abnormalities.

When this test is required

The test is typically requested by a doctor or specialist when they suspect a patient may have a condition affecting the skull base or surrounding structures, based on the patient’s symptoms or other diagnostic tests.

What the Test Detects

The test is used to generate detailed images of the skull base and surrounding structures, including the brain, blood vessels, nerves, and bones. The contrast dye injected into the patient’s bloodstream highlights the blood vessels and helps to identify any abnormalities.

Preparation for the Test

The patient may need to fast for a few hours before the test and avoid certain medications that could interfere with the imaging results. They should inform their doctor if they are pregnant or have a history of kidney problems.

Sample Requirements

No sample is required for this test.

Additional Notes

As with any medical imaging test, there is a small amount of radiation exposure associated with a CT skull base with contrast. The contrast dye used can also cause some people to experience allergic reactions or kidney problems, so patients should inform their doctor if they have a history of either. Additionally, if the test reveals significant abnormalities or conditions affecting the skull base, the patient may need further testing or treatment to manage the condition.
