This test is typically done to evaluate symptoms related to the inner ear or temporal bone, such as hearing loss, tinnitus, vertigo, or ear infections. It can also help identify any abnormalities or damage to the ear or surrounding structures.
When this test is required
This test may be requested when a healthcare provider suspects an underlying condition affecting the ear or temporal bone, or when a patient is experiencing symptoms such as dizziness, vertigo, hearing loss, or ear pain.
What the Test Detects
This test uses X-rays and a contrast agent to create detailed images of the inner ear and temporal bone. The contrast agent is injected into a vein before the scan to highlight the blood vessels and soft tissues in the area, making it easier for healthcare providers to see any abnormalities.
Preparation for the Test
Patients may be asked to avoid food or drink for several hours before the test, depending on the specific instructions from their healthcare provider. Patients should also inform their provider of any allergies, particularly to iodine or contrast agents.
Sample Requirements
No specific sample is required for this test.
Additional Notes
Patients may be asked to remove any jewelry or other metal objects before the test, as they can interfere with the X-ray images. Patients should also inform their healthcare provider of any medications they are taking, as certain medications can interfere with the test or increase the risk of side effects
