Pearson Prentice Hall Upper Saddle River, NJ 07458 X-rays Traditional X-rays use electromagnetic waves to produce an image on film. Digital X-rays are immediately available on a screen and expose the patient to less radiation. Used for broken bones. Cannot image soft tissue.

3. Information Technology for the Health Professions, 2/e By Lillian Burke and Barbara Weill ©2005 Pearson Education, Inc. Pearson Prentice Hall Upper Saddle River, NJ 07458 Ultrasound Uses sound waves and the echoes they produce to generate an image Moving image Uses no radiation Used to study developing fetus and to diagnose prostate disease and gallstones

4. Information Technology for the Health Professions, 2/e By Lillian Burke and Barbara Weill ©2005 Pearson Education, Inc. Pearson Prentice Hall Upper Saddle River, NJ 07458 CT Scans Computerized tomography uses X-rays at many angles from which the computer creates an image. Soft tissue can be imaged. More accurate and detailed images decrease the need for exploratory surgery.
