Magnetic resonance imaging (MRI) is a test that produces images of internal organs and structures virtually anywhere in the anatomy of the body utilizing a strong magnetic field and interaction with radio waves.
Computerized tomography (CT/CAT) scan is a specialized type of x-ray that takes thin slice-like images of the body to visualize internal structures.
Ultrasound, also referred to as sonography, is a type of medical imaging that uses high-frequency sound waves to produce internal images of the body in real time.
Fluoroscopy is a study of moving body structures--similar to an X-ray "movie." A continuous X-ray beam is passed through the body part being examined.
A digital x-ray is a test that produces images by momentarily passing x-ray radiation through a part of the body.
