MRI is a noninvasive technique which does not require exposure to ionizing radiation.
X-Ray Computed Tomography (CT), sometimes referred to as Computerized Axial Tomography (CAT), is a diagnostic tool which produces images representative of slices of the body, allowing the radiologist and physicians to view cross sections and get a more accurate view of structures within the body.
Ultrasound imaging (sonography) uses high-frequency sound waves to view inside the body. The ultrasound image is produced by the reflection of the waves off of the body structures.
X-ray is the name of the procedure as well as the name of the beams that are sent through the body.
