Cranial CT scan
Alternate Names : Brain CT, Head CT, CT scan - skull, CT scan - head, CT scan - orbits, CT scan - sinuses
Risks
Iodine is the usual contrast dye. Some patients are allergic to iodine and may experience a reaction that may include hives, itching, nausea, breathing difficulty, or other symptoms. As with any x-ray examination, radiation is potentially harmful. Consult your health care provider about the risks if multiple CT scans are needed over a period of time.
Special Considerations
A CT scan can decrease or eliminate the need for invasive procedures to diagnose problems in the skull. This is one of the safest means of studying the head and neck. Alternative tests that may be performed in place of Cranial CT scan include: - MRI of the head
- Positron emission tomography (PET) scan of the head
- Skull x-ray
