Segmentation results (left to right) the MRI data, base case, sub‐cube method, and region‐growing method. The red voxels shown across the results represent those missed by the various methods but identified by the physician: these are the false‐negatives. The purple voxels in the results are those not identified by the expert but flagged as lesion voxels by the corresponding method, i.e., the false‐positives. The green voxels are those identified as lesions by the expert and the corresponding method or the true‐positives.
