MRI Overview

Magnetic Resonance Imaging (MRI) is a widely used imaging system that safely creates many different and detailed views of the inside of the body. A MRI scanner is a large tunnel-shaped machine that will accommodate an adult lying down. Within the MRI scanner is a large magnet. The magnet directs harmless radio signals around sections of the body. When the signals pass through the body, they resonate, that is, release a signal. The signals are picked up by a receiver inside the MRI scanner and then sent to a computer. The computer analyzes the signals and converts them to a visual image that is displayed on a viewing monitor and then printed on special film. The images produced by the MRI scanner are gray-scale images similar to an X-ray.

These gray-scale images can be difficult and time-consuming to read. A radiologist “reads” these images on film by comparing the different scans of each tissue slice, sometimes evaluating one hundred (100) to three hundred (300) individual gray images to obtain a diagnosis. The successful diagnosis of a condition using MRI depends not only on the ability of the radiologist to detect the subtle differences in shades of gray, but also the radiologist’s ability to visually compare the vast number of individual images.

Because human vision is keyed to color, we believe that software products provides radiologists, doctors and patients an opportunity to look at MRI images in a more intuitive way. The software applications are valuable for educating patients or a research team, or for showing a surgeon who may not have experience in interpreting MRI images how he or she can visualize and understand them better. Following FDA approval, the RevColorTM MRI technology also has great potential to be used for surgical planning and for diagnostic purposes.
