In many clinical contexts, detecting all lesions is imperative for evaluating
disease activity. Standard approaches pose lesion detection as a segmentation
problem despite the time-consuming nature of acquiring segmentation labels. In
this paper, we present a lesion detection method which relies only on point
labels. Our model, which is trained via heatmap regression, can detect a
variable number of lesions in a probabilistic manner. In fact, our proposed
post-processing method offers a reliable way of directly estimating the lesion
existence …
