What is CT Angiogram?
A Computed Tomography Angiogram or CTA scan is an imaging test that combines computers and 360-degree x-rays to produce highly detailed images of the blood vessels of the body. CT Angiography is commonly performed to evaluate for blood vessel disorder problems such as aneurysms (balloon like bulging), stenosis (narrowing), dissection (wall splitting), malformations or fistula (abnormal vascular connections). These conditions can occur in the brain, neck, spine, chest, abdomen (such as liver and kidneys), and legs.
CP Advanced Imaging is committed to delivering the best possible care and providing excellent image quality while using the lowest possible level of radiation. Through our equipment and expertise, your exam will be performed with advanced radiation reduction technology and optimized protocols . This will maximize results while minimizing radiation dose.
Equipment: Our CT and PET/CT units feature advanced radiation dosage reduction technology including SAFIRE which has been shown to decrease radiation by 60%.
Expertise: Our physicians have developed protocols which are tailored to evaluate the area of interest. The protocols meet national benchmarks and are well below the radiation dosage thresholds.
We are committed to delivering the best possible care at the lowest radiation dose possible.
How to Prepare?
Do not eat 4 hours prior to the exam. You should wear loose, comfortable clothing, avoiding garments that have zippers, belts, or buttons made of metal. You may be asked to wear a gown during the procedure. You will be asked to remove keys and jewelry from the area being scanned.
Women should always inform their physicians and the technologist if there is any possibility of pregnancy.
What to Expect?
The CTA requires an injection of contrast dye for which an IV will be started. The technologist will then comfortably position you on an exam table which will then slowly pass through the CT scanner.
Depending on the type of exam, the portion requiring intravenous contrast injection usually lasts only 10 to 30 seconds while the entire scan time is usually completed in minutes.
