Which of the following represents three types of imaging studies?

The correct option includes three types of imaging studies: CT, MRI, and X-ray. These modalities are all widely used in medical practice to visualize the internal structures of the body.

CT, or computed tomography, uses X-ray technology to create detailed images of internal organs, bones, and tissues. It's particularly useful for assessing complex fractures, internal bleeding, and other conditions where precise images are required.

MRI, or magnetic resonance imaging, employs powerful magnets and radio waves to generate detailed images of organs and soft tissues inside the body. It is especially effective for imaging the brain, spinal cord, and soft tissues like muscles and ligaments.

X-ray is one of the most basic forms of medical imaging, utilizing low doses of radiation to create images primarily for viewing bones and detecting fractures or infections.

In the context of the other options, while some included studies may be related to diagnostics, they do not all pertain specifically to imaging. For example, CBC refers to a complete blood count, which is a laboratory test, not an imaging technique. Similarly, an EKG, or electrocardiogram, is used to assess cardiac electrical activity, rather than providing images of body structures. Thus, the selection of CT, MRI, and X
