Abstract
As recently as 10 years ago, computed tomography (CT) angiography (CTA) was first described as a technique to non-invasively evaluate vascular structures via a peripheral injection of contrast. The first clinical application of this technology for the upper extremities was with single-row helical scanners where the technique was used to evaluate the configuration and patency of the subclavian arteries. With the recent introduction of multi-detector technology including widespread availability of 16-and 64-detector scanners, the use of CTA to evaluate the upper extremity vascular supply is rapidly replacing conventional angiography, not only for diagnosis but also for treatment planning. The recent technologic advancements with multi-detector CT (MDCT) now allow large volume coverage with higher spatial resolution. This chapter reviews the technical factors that must be taken into consideration in planning and interpreting CTA, as well as the applications that are most relevant to arterial pathology of the upper extremity.
