The test may be ordered to evaluate and diagnose a range of conditions affecting the brain and surrounding structures, such as tumors, bleeding, swelling, infections, or abnormalities in the blood vessels.
When this test is required
The test is typically ordered by a doctor or specialist when they suspect a patient may have a condition affecting the brain or surrounding structures, based on the patient’s symptoms, medical history, or other diagnostic tests.
What the Test Detects
The test produces detailed images of the brain and surrounding structures, including the orbits (eye sockets), which can help diagnose and evaluate a range of conditions affecting these areas.
Preparation for the Test
The patient may need to change into a hospital gown and remove any metal objects, such as jewelry or clothing with zippers or buttons, before the test. They may also need to fast for a few hours before the test or drink a contrast solution to improve imaging results.
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 Brain and Orbits (with I/V 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, the test may not be suitable for pregnant women or individuals with kidney problems.
