College of Radiographers CPD Endorsed, Computed Tomography
Module:
Aspects of Computed Tomography Angiography & Atherosclerosis (Renal CTA)
Module Description:
Volumetric Computer Tomography (CT) scanning was first introduced in 1991, using spiral or helical single detector CT (SDCT) technology. Since that time, the technology has continued to grow with the development and introduction of multidetector CT (MDCT) scanners.
As you would expect, these new technologies began an explosion of new CT applications including Computer Tomography Angiography (CTA). CTA has become a focal topic of radiology, in part to the relatively new understanding of vascular disease. In addition, CTA has developed into an established technique for studying specific arteries such as the renal and aortic-iliac arteries.
The key to any successful study is study planning. In order to select the correct scan protocol you must be aware of the reason the CT scan is being ordered. Before discussing any of the specific CTA applications, it is important to first, realize the mechanism causing vascular disease and how CTA will provide diagnostic information. We will start this module by exploring the vascular anatomy and physiology, followed by the disease process, and the information that CTA provides for diagnosis.
Learning Objectives
* distinguish advantages of multi-detector computer tomography (MDCT) technology
* describe blood vessel anatomy and physiology
* discuss the current role of CT angiography (CTA), with a specific focus on renal artery examinations
* compare renal CTA with conventional vascular examination methods
* discuss the dynamic causes of atherosclerosis
