FONAR COMPLETES INSTALLATION OF SUBSIDIARY'S
4TH STAND-UP MRI, FIRST IN FLORIDA

          MELVILLE, NEW YORK, April 12, 2004 - FONAR Corporation (NASDAQ-FONR), The MRI Specialist™, announced today the opening of Stand-Up MRI of Boca Raton, P.A. in Boca Raton, Florida. Stand Up MRI of Boca Raton is the fourth Stand-Up™ MRI facility managed by Health Management Corporation of America (HMCA), FONAR's physician and diagnostic services management subsidiary. The new facility is located at 9080 Kimberly Blvd. in Boca Hamptons Plaza, Boca Raton, Florida [(561) 470-1890].
          Raymond V. Damadian, M.D., president and chairman of FONAR, said, "We are delighted to have our fourth HMCA-managed Stand-Up™ MRI scanning center up and running. We expect that before too long it will be adding to the success of the first three. Last month, our Islandia, New York facility, the first HMCA managed Stand-Up™ MRI facility, completed over 450 scans; the Bensonhurst, New York facility, the second, completed over 400 scans for the first time; and the Staten Island, New York facility, the most recent of the three, completed over 200 scans. Our plan is to complete Stand-Up™ MRI upgrades at as many HMCA-managed sites as possible." The new Boca Raton installation is an upgrade of the HMCA-managed facility in Deerfield Beach.
          "The Boca Raton area has a very sophisticated medical community," continued Dr. Damadian, "so we expect the physicians will quickly embrace the new diagnostic technology that only the Stand-Up™ MRI can offer." The Stand-Up™ MRI is the only whole-body MRI that allows patients to be scanned in normal upright, weight-bearing positions, either standing or sitting, as well as in any other position in which the patient is symptomatic. The Stand-Up™ MRI has detected pathology that was missed on conventional lie-down MRIs, pathology that could never be detected on a lie-down scanner.
          "I also expect that the residents in the Boca Raton area will be very happy to have the Stand-Up™ MRI in their community," continued Dr. Damadian. "The unique magnet design of the Stand-Up™ MRI makes it dramatically different from any other MRI scanner. Patients are typically scanned in a comfortable seated position watching a 42" flat-screen TV. There is nothing in front of the patient's face or overhead to create the "closed-in" feeling that is typical of other MRIs, even some Open MRIs. The people of Boca will be relieved to know that should they ever need an MRI scan, they have the most patient-friendly MRI in existence in their own backyard."
          The Stand-Up™ MRI is the world's only whole-body MRI scanner with the ability to perform Position™ Imaging (pMRI™), i.e. patients can be scanned standing, sitting, bending or lying down. Because of its unique top-open and front-open magnet design, the Stand-Up™ MRI is remarkably spacious and non claustrophobic.
