This 2011 SPIE Medical Imaging paper examines how MRI intensity variation affects automatic anatomical structure recognition. Its evaluation considered multiple ankle-complex scenarios and found that intensity variation among images degraded recognition performance.
Summary
The paper studies whether intensity non-standardness—the lack of a consistent numeric meaning for MRI intensities across images—affects automatic recognition of anatomical structures. The authors evaluated 31 scenarios involving multiple objects from the ankle complex and introduced seven levels of non-standardness. They report that intensity variation among images in an ensemble degraded object-recognition performance. The reported evaluation concerns this experimental setup; it does not establish clinical readiness or prospective clinical performance. View the paper.
