Results Six hundred adult patients had blunt TBI and underwent head CT as a part of their evaluation. Of these 600 patients, 132 (22%) underwent head CTA in addition to CT. Only one patient had altered management after the CTA results; the patient had a diagnostic angiogram that was ...
A cardiac computerized tomography (CT) scan – which can also be referred to as a coronary CT angiography or CT angiogram – is an imaging test to view the heart and blood vessels. It is a test that carries few risks and is less invasive than alternative procedures such as an angiogram....
