What's New in Diagnostic Imaging?

The ACA Council on Diagnostic Imaging (CDI) serves to collect and disseminate the most current and state-of-the-art information about the practical and scientific phases of diagnostic imaging techniques to the chiropractic profession, as well as to encourage and promote the advancement of diagnostic imaging through education, research and public relations.

As with many of the ACA’s specialty councils, several CDI members are active in chiropractic academia, frequently contribute manuscripts to professional journals and are authors of many academic texts. Our main educational work is accomplished through our peer-reviewed publication, Topics in Diagnostic Radiology and Advanced Imaging, and our annual symposium.

This year, the CDI spring annual symposium, which offers 12 hours of continuing education for most states, will be held May 2-3, 2009, at the Mandalay Bay Resort and Casino in Las Vegas. Students and all practitioners are welcome and invited to attend; current council members receive a discounted registration rate. This year’s presentations will include imaging of spinal instability, bone marrow magnetic resonance imaging (MRI), MRI of shoulder and knee, and nuclear medicine. (See sidebar for a preview of the presentation on nuclear medicine.) We encourage ACA members to apply for council membership and to attend this year’s symposium.

Nuclear Medicine

By Gregory Katsaros, DC, DAAPM

Nuclear medicine, a subspecialty of radiology, is unique in its ability to demonstrate physiologic processes rather than anatomic information. The basis of nuclear medicine is generally through perfusion, a process in which the patient is injected with a combination of a radioisotope and a pharmaceutical agent, called a radiopharmaceutical. The pharmaceutical agent is similar to the body’s natural substances used for the specific region; for example, phosphates are used for skeletal imaging. These radiopharmaceuticals localize in their specific regions and emit gamma rays, which can be detected via a gamma camera, and the regions can be evaluated for activity.

Nuclear medicine is more sensitive than other imaging modalities; however, it is not as specific. The sensitive physiological information obtained from nuclear medicine studies is invaluable in many aspects of patient care, helping to detect pathology earlier and often obviating the need for more invasive procedures.

Gregory Katsaros, DC, DAAPM, a member of the American College of Nuclear Physicians, is assistant chief of technology at the Arizona Regional Medical Center,  physician and medical director of integrative pain management in Tempe Arizona, and adjunct faculty in the department of health sciences at Gateway Community College-Maricopa Community Colleges in Phoenix, Ariz. He will be presenting the topic of nuclear medicine at the upcoming CDI symposium. For more information, go to www.cditoday.org.
