Multislice CT angiography

Abstract

Multislice CT uses the basic principles of spiral CT, but allows more rapid acquisition of multiple data sets, making scan times shorter and artefact less likely. Multislice technology allows for improved image quality in breathless and uncooperative patients. In the diagnosis of pulmonary embolus, segmental and subsegmental detail is improved. Cardiac imaging is improved by ECG gating. Images similar to catheter angiograms can be obtained in the extremities and the cervical arteries. In trauma cases, a single multislice CT investigation may be able to replace a number of modalities that would previously have been necessary.
