Test Details & Preparation

CT angiography is used to examine the blood vessels the abdomen and pelvic area. Routine protocol is to perform a CTA of the abdomen and pelvis together because the aorta extends from the abdomen into the pelvis.

For contrast exams, patients on glucophage/metformin need a current creatinine within 30 days of the test. Additionally, the patient must not take medications the day of the test and should remain off these medications for 48 hours after the CT. If the creatinine was normal prior to the CT, the patient may resume medications in 48 hours.

A current creatinine (30 days) is required if the patient is 60 years of age and older has diabetes, hypertension, or renal insufficiency. Additionally, the patient must be NPO for 6 hours prior to the exam. The patient should also inform his doctor of any recent illnesses or other medical conditions, and if he has a history of heart disease, asthma, diabetes, kidney disease or thyroid problems. Any of these conditions may increase the risk of an unusual adverse effect.

The patient will be asked to remove any jewellery and clothing. He will be given a gown and the technologist will obtain a medical history. The patient will be instructed to lie on his back during the exam. Because contrast is indicated, the technologist will start an IV. The patient may feel warm and flushed for a few seconds. The patient will be asked to remain very still during the scanning process and will be given specific breathing instructions. The scan should take approximately 5 minutes, but the visit may require up to 30 minutes.

The patient may resume normal activities following the CT. If a contrast material was used and the patient is on glucophage/metformin, the patient must stay off the medication for 48 hours. If the patient’s creatinine was normal prior to the CT, the patient may resume taking the medication in 48 hours.
