A vascular necrosis (AVN) of the femoral head is a common yet poten(cid:173) tially serious disorder which can be detected in its very early stages with magnetic resonance imaging. We have developed multi-layer perceptron networks, trained with conjugate gradient optimization, which diagnose A VN from single magnetic resonance images of the femoral head with 100% accuracy on training data and 97% accuracy on test data.
