We, basically, use the MRI when examining the head. However, if for any reason that is not possible, then the CT is used. The images will show the elements of the brain, veins and bones together with developmental variations, abnormal ventricles and certain primary and secondary tumors. The CT is also recommended in trauma cases in order to rule out fracture of the skull and possible blood effusion
No special preparation is required, only that you must come on an empty stomach on the day of your CT scan. If intravenous contrast material is to be administered, certain diabetes medicines should not be taken, thus, it is important that you consult with your doctor beforehand. In any event, it is best to come prepared for contrast material.
A CT series of the skull is prepared - one with and one without contrast material. Also, one series of bones one of soft tissues is prepared in every case.
There are no real contraindications. In case of contrast allergy, of course, we will not give any to the patient. You should consult with your doctor in every case to discuss which examinations are worth taking.
