MELVILLE, N.Y.--(BW HealthWire)--Nov. 20, 2000

FONAR Corporation's (NASDAQ-FONR) Stand-Up MRI(TM) (magnetic resonance imaging) was reported at a scientific symposium given by J. Randy Jinkins, M.D., FACR. Dr. Jinkins reported his findings with patients using FONAR's Stand-Up MRI(TM) (Indomitable(TM)) at the Spine Imaging Symposium of the Los Angeles Radiological Society, on November 11, 2000. Dr. Jinkins described the details of FONAR's Stand-Up MRI(TM) and the impact of being able to perform positional MRI (pMRI) on patients as well as obtaining Weight-Bearing MRI(TM) examinations.

Dr. Jinkins told the audience, "The Stand-Up MRI(TM) offers radiologists and referring physicians weight-bearing, dynamic-kinetic MRI imaging studies of the spine that have previously been unavailable. Very significant anatomical changes are found when comparing recumbent (lie-down) position MRI scans and upright, Weight-Bearing MRI(TM) studies. For example, the Stand-Up MRI(TM) offers the potential to reveal such weight-bearing and position dependent disease as fluctuating disc herniations, variable spinal stenosis and hypermobile spinal instability."

The MRI scans of several cases were demonstrated. Dr. Jinkins discussed them in detail, showing side-by-side the recumbent scans with those done with the patient in the upright position. "There is an important clinical need to be able to compare recumbent scans with Weight-Bearing MRI(TM) scans for a clear diagnosis. The changes between the two positions can be relevant clinically. Indomitable(TM), with its uniquely designed, multi-positional patient scanning system can potentially fulfill a long list of needs that have remained unsatisfied for too long."

Dr. Jinkins said, "0.6 Tesla (mid-field) may be the optimal field strength for imaging the spine. This is because there are less motion and chemical shift artifacts on the images acquired at 0.6 Tesla than at 1.5 Tesla (high-field). Another advantage of Indomitable(TM) includes its Top-Open(TM) design which may well be the least claustrophobic machine in the MRI industry. In addition, the versatile tilt-translation patient positioning system has direct applicability to future technological advances such as contrast enhanced MRI myelography."

Dr. Jinkins concluded, "Now that I have had the opportunity to work with Indomitable(TM), I feel that I will not be able to completely trust the spine images from a recumbent-only MRI again."

J. Randy Jinkins, M.D., FACR, is a native Texan, having attended and taught at the University of Texas Health Science Center in San Antonio for many years. Currently he is a research neuroradiologist at the University of Nebraska. In January Dr. Jinkins will take the post of Professor and Director of Neuroimaging Research at SUNY Downstate Medical Center, Brooklyn, New York.
