I. Introduction
Deep learning and deep neural networks (DNNs) have garnered considerable attention in recent years, and are becoming more wildly used in medical settings. Incorporating AI-based tools in the medical practice should come as no surprise considering they operate much quicker than humans, are immune to fatigue, and can be rapidly deployed anywhere across the globe, while still achieving high levels of accuracy. There are numerous studies demonstrating the enhanced capacities of DNNs for diagnosis based on medical scans and images, for various conditions starting from bone fractures [1] to various skin diseases [2] to breast cancer [ 3 – 4 ], lung cancer [5] and more, which are not only comparable to but also surpassing the results obtained by the average experts and practitioners in the respective field. The full capabilities of these algorithms however are far greater as they can also be instrumental in facilitating a deeper understanding of the intricate nature of diseases. In their comprehensive overview of applications of computer-assisted image analysis in clinical oncology, Cai & Hong show how these technical developments not only make possible the reliable identification of brain tumors, but also enable the development of more intelligent and complex approaches for assessment of their response to treatment [6] .
