Whole body magnetic resonance imaging (WB-MRI) is the recommended modality for diagnosis of multiple myeloma (MM). WB-MRI used to detect sites disease across entire skeletal system, but it requires significant expertise and time-consuming report due great number images. To aid radiological reading, we propose an auxiliary task-based instance learning approach (ATMIL) MM classification with abil...
