The pattern of vascular pathology on multidetector computerised tomography angiography In Kenyatta National Hospital

Abstract

The development of multidetector Computer Tomography (MDCT) has revolutionized CT angiography (CTA). New techniques and software are currently being developed and modified to improve CTA. The advantage of MDCT relevant to CTA is the ability to acquire high resolution, near isotropic data sets in a shorter acquisition time. Also important is the ability to achieve a longer scanning range in the arterial phase, which has led to the introduction of CTA of the peripheral arterial system. Image processing techniques have also progressed rapidly, with simplification of a previously cumbersome process. The high spatial resolution and relatively non-invasive nature of MDCT angiography are favourable factors against established vascular imaging techniques. The implication of this is that traditional diagnostic pathways for evaluation of the vascular system will become less relevant, as the value of MDCT angiography becomes fully established.
