IMG181 IMG182 IMG183 Head injury Almost never Tumor Headache When a non-contrasted study Suspected CA CVA / TIA has already been performed Evaluation for METS Suspected CVA Abscess/Infection Seizures Chronic SDH (MRI better) Dizzy Altered Mental Status Altered Level of consciousness Syncope IMG2013 Fatigue and malaise Circle of Willis (Aneurysm) General weakness

Occasionally, indications for contrast are discovered during routine non-contrast exams. In such cases, every effort will be made to perform the appropriate study according to the radiologist.

Appy’s can be scanned either w/ or w/o contrast, each w/its own advantages. The trend seems to be w/o contrast. We will scan it as you order it.

All routine Abd/Pel exams include oral contrast. The “with or without” contrast refers to the IV contrast portion of the study. Oral contrast can be omitted on request.
