CT Exam – What to Expect (Preparing for your CT by reviewing what to expect

before, during and after…)

CT Exam

CT (Computed Tomography) or “CAT” Scan is a fast and painless diagnostic exam that combines X-rays and computers. The result is a detailed picture that can identify problems with soft tissues, organs, and bones. A CT scan provides information to the Radiologist about the location, nature and extent of many different diseases or abnormalities inside your body.

Our hospital has a multi-slice helical CT GE Scanner installed April 2013 which generates detailed data quickly and accurately.

Examination can be done with  or without oral and intravenous contrast administration.  For those examinations that need an IV contrast administration and the patient is over 50 or has other renal disease, a creatinine must be done prior to the examination.  In some instances if the creatinine has been in the past three months, this will be adequate.
