Fig. 4From: Detection of femoropopliteal arterial steno-occlusion at MR angiography: initial experience with artificial intelligenceExemplary occlusion map, heatmap overlaid on the input image, depicts a neural network trained to detect arterial steno-occlusions on the left side (a) and the right side (b). The overlaid colour intensity indicates which areas of the image were most important to the neural network for its classification taskBack to article page
