CT Angiogram of the Pelvis - Overview & Technique

Computed tomography (CT) angiography is a relatively new procedure that provides high-resolution vascular images and detailed images of the adjacent bone and soft tissue. It is relatively non-invasive, with injection of the contrast medium through a peripheral vein. The accuracy of arterial visualization provided by CT angiography is comparable to that of DSA, and venous phase images are easily obtained.  Additionally, three-dimensional reformatting allows for excellent appreciation of anatomic relationships between bones, soft tissues, and the vascular system. Application of CT angiography is becoming more widespread, both for major vessel evaluation (thoracic and abdominal aorta) and smaller vascular beds such as the cerebral, pulmonary, renal, and mesenteric arterial systems. Computed tomographic angiography is a reliable and convenient imaging modality for diagnosing arterial injuries after blunt and penetrating trauma to the extremities. It is a noninvasive modality that could replace conventional arteriography as the initial diagnostic study for arterial injuries after trauma to the extremities.

Pelvis CTA - Benefits

• CTA can be used to examine blood vessels in many key areas of the body, including the brain, kidneys, pelvis
• Rapid injury assessment, no time wasted
• less discomfort because contrast material is injected into an arm vein rather than into a large artery in the groin.
• CT can be performed if you have an implanted medical device of any kind, unlike MRI.
• CT imaging provides real-time imaging, making it a good tool for guiding minimally invasive procedures such as needle biopsies and needle aspirations of many areas of the body, particularly the lungs, abdomen, pelvis and bones.
• A diagnosis determined by CT scanning may eliminate the need for exploratory surgery and surgical biopsy.
• No radiation remains in a patient's body after a CT examination.
• X-rays used in CT scans usually have no immediate side effects.

CT Angiogram of the Pelvis - Positive Findings

• Assessment of significant ischemia in the presence of ulcers or gangrene or symptoms of significant claudication.
• Assessment of disease of large vessels:  aneurysm, dissection, AV malformations and fistulas, intramural hematoma, vasculitis.
• Arterial entrapment syndrome.
• Venous thrombosis, if diagnosis is not clear from other studies.
• Vascular invasion or displacement by tumor.   
• Pre/Post-operative or interventional vascular procedure for luminal patency versus re-stenosis (due to atherosclerosis, thromboembolism, intimal hyperplasia and other causes) as well as complications such as pseudoaneurysms related to:
• Surgical bypass grafts.
• Vascular stents and stent-grafts.
