Computed Tomographic Angiography (CTA) Essay Example | Topics and Well Written Essays - 250 words

Computed Tomographic Angiography (CTA) - Essay Example Due to its enhanced, temporal and spatial resolution, it has been utilised as a less invasive technique in the diagnosis of coronary artery disease. Aneurysms rise in occurrence with age; they are more common in women and are connected to certain genetic conditions. CTA has been proposed as an alternative choice for intra – arterial digital subtraction angiography to check for aneurysms. CTA is used to characterise cerebral aneurysms for assessing the possibility of their rupture. It helps produce 3D geometries of cerebral aneurysms. Coronary lesions are risked to ruptures. CTA scanners avail for detection, quantification and characterization of coronary atherosclerotic lesions. Non invasive CTA is utilised to recognize patients with high or low risk chances of developing cardiac conditions due to the constitution of plaques. Computational fluid dynamics permits for computation of lesion particular endothelial shear tension. They also permit partial flow reserve. This adds functional details to evaluation of plaques.
