Diagnostic Medical Sonography

This guide is designed to help you find reliable, accurate information about diagnostic medical sonography


Diagnostic medical sonographers operate special imaging equipment to create images or to conduct tests. They have skills in record keeping, reviewing and recording pertinent clinical patient history, performing the sonographic examination, providing for the comforts and needs of the patient during the examination, and recording the anatomic, pathologic and physiologic data for interpretation by the supervising physician. Diagnostic sonography and radiology technology are sister fields, related, but quite different. Radiology technologists specialize in radiation imaging and therapy, using X-ray, computer tomography and medical resonance imaging to capture images of the human body. On the other hand, sonographers are trained to use ultrasound technology, which emits sound waves to take internal images of the body.
