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

Abstract

To date the diagnosis of carpal instabilities due to ligament lesions relies upon a qualitative examination of the patient's wrist. This paper presents a novel system where sequences of magnetic resonance images (MRI) are automatically analysed to measure the motion of several 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 different wrist positions can be measured giving a detailed insight into the motion of the bone
