These procedures involve the injection of iodinated contrast media to demonstrate diseases of the heart and blood vessels.  Computed tomography (CT) technologists produce images of selected planes of the body by combining the use of an X-ray beam and a computer. Magnetic resonance imaging (MRI) technologists utilize a magnetic field along with radio waves to create images of patients' anatomy for interpretation by a radiologist.  Mammography technologists operate mammography equipment to produce images of the breast for diagnostic purposes.

Diagnostic medical sonographers are concerned with the proper operation of the ultrasound equipment and preparation of patients for various types of diagnostic procedures. Upon request of a physician, they examine various parts of the body by using sound waves.
