Fig. 2From: Novel computer aided diagnostic models on multimodality medical images to differentiate well differentiated liposarcomas from lipomas approached by deep learning methodsFeature heatmaps of representative patients on the deep learning ResNet50 algorithm via the Guided Grad-CAM. The original CT and MRI images and their corresponding feature heatmaps were shown from left to right. The red color highlighted the region of interest to classify lipoma and WDLPS. The red color focused on different area for lipomas (A) and WDLPS (B) on CT (Left), T1WI (Middle) and T2FS (Right) MRI images, respectively.
