Beginning with the x-ray, Radiology has become a vital part of diagnosis. Radiology is the science and technology of using forms of radiation or energy for which the body is partly transparent to image the organs inside. The contents of the body are shown by shadows on recording media. Although ultrasound is not a form of radiation, the category of radiology also includes the use of ultrasound or focused high-frequency sound which images internal organs using echoes that are traced precisely enough to form an interpretative image. Modern radiology also makes use of the magnetic properties of the body's own molecules to generate magnetic resonance images (MRIs), but this is a very recent development.
What Is a Radiology Information System (RIS)? Radiology information systems (also referred to as RIS) are networked software systems designed to manage medical imagery and the associated data that comes along with it. There are several basic functions that comprise an RIS.
There are many aspects of MACRA, and it's important you're familiar with all of them.
