The study was part of ongoing research at the UPRIGHT® MRI CENTER at FONAR Corporation, which invented the UPRIGHT® MRI scanner. Research at the center, which is located in Melville, New York, has already provided unique diagnostic views of the upright spine with the weight of the body on it, including the spine with the patient bending forward and backward, radiation-free monitoring of scoliosis, upright imaging of pelvic floor problems in women, such as a prolapsed bladder or uterus, sit-down imaging of the prostate without the usual endorectal coil, and a walk-in, sit-down 10-minute scan that allows for cost-effective MRI scanning of patients undergoing chemotherapy to monitor tumor responses biweekly.

About the ResearchersRaymond V. Damadian is the medical doctor who first proposed scanning medical patients by NMR (nuclear magnetic resonance, the original name of the MRI) based on his discovery of the principle on which all modern MRI is based – the different NMR signals that tissues emit in a magnetic field. The amplitude of these signals accounts for the pixel brightness in every MRI image. He discovered that the NMR signal amplitudes of cancer tissue differ markedly from the NMR signal amplitudes of the normal tissues because of the differences in their rate of decay. He simultaneously discovered that the NMR signal amplitudes also differ markedly among the normal tissues themselves because of the differences in their rates of decay. These signal amplitude differences enabled cancer tissues and other tissues to be visualized in MRI images because the signal differences generate the needed brightness differences (contrast) in the picture elements (pixels) needed to visualize detail in the MRI image. The contrast in pixel brightness allows the cancer pixels in the image to be distinguished from the surrounding normal pixels. It also allows the different normal tissues to be distinguished from each other and achieve the exceptional anatomic detail MRI pictures are known for. Damadian went on to build the first MRI scanner by hand, assisted by two post-doctoral students, at New York's Downstate Medical Center and achieved the first MRI scan of a healthy human body in 1977 and a human body with cancer in 1978. For these discoveries he received the National Medal of Technology from President Reagan in 1988, was inducted into the National Inventors Hall of Fame in 1989 as the inventor of the MRI and was named Inventor of the Year in 2007 for his invention of the FONAR UPRIGHT® Multi-Position™ MRI. He founded FONAR to bring MRI diagnosis to patients. The company manufactured and installed the world's first commercial MRI in 1980. Damadian is currently FONAR's president and chief research officer. David Chu is the head MRI scientist at FONAR who specializes in the imaging of the cerebrospinal fluid with advanced cines, or movies, which allow for observation of CSF flow in real time. The technology, which the company calls TrueFlow™ Imaging, made the diagnostic breakthrough in multiple sclerosis possible. SOURCE FONAR Corporation
