An Image Analysis Study On Thigh Muscles And Cross-sectional Area Determined By MRI

A computerized pattern recognition of magnetic resonance imaging (MRI) which the high quality for use in making quantitative diagnosis based on the histogram analysis and its application is accessible. A histogram shows display information how often pixel runs of a certain length and a certain gray level range are occurred in the image. By carrying out MR scans at forty-two evenly spaced levels along the right thigh of the volunteer, the histogram showing the differences in the distribution of shades within a region of interest (ROI) of in vivo determinations of cross-sectional area (C SA) of individual muscle. This study clearly demonstrates the clinical usefulness of the histogram as a diagnostic tool and the simplicity of measurements of CSA of a personal computer on video images of the MRI. To perform the manipulations and programming one of commercially available software and hardware are outlined.
