Automatic analysis of magnetic resonance (MR) sequences for the diagnosis of ligament lesions

To date the diagnosis of carpal instabilities due to ligament lesions relies on a qualitative examination of the patient’s wrist. This paper presents a novel system where sequences of magnetic resonance images are automatically analysed to measure the motion of seven wrist bones. Resulting motion graphs provide a quantitative basis for diagnostic as well as scientific purposes. As the imaging method is non-invasive up to twelve wrist positions can be measured giving a detailed insight into the bone’s motion.
