The term CAT SCAN RELATIVE refers to three imaging techniques used in medical diagnostics: Axial, Rads, and MRI. Axial is a type of computed tomography (CT) scan that takes multiple X-ray images from different angles to create a detailed 3D image of the body. Rads stands for radiographs, which are X-ray images that can be used to diagnose bone fractures or other abnormalities. MRI stands for magnetic resonance imaging, which uses a strong magnetic field and radio waves to create detailed images of the body's internal structures.
