Computed tomography (CT) and magnetic resonance imaging (MRI) are imaging technologies that create cross sections or "slices" of the body part being scanned. This module covers the basic principles of CT, spiral CT and MRI scanning, the differences between them, and advantages of each. It provides an understanding of the technology and techniques involved in using these advanced imaging modalities. If you are studying for the American Registry of Radiologic Technologists® (ARRT) registry exams, this module is ideal.
You’ll learn
- what computed tomography is and how it is achieved
- the differences between conventional tomography, computed tomography, and spiral computed tomography
- to identify the different components of a CT system and visualize how a CT system works
- to describe how MRI works, and its indications and contraindications
- much more (see “content details” for more specific information)
