Child Brain Tumors can be Classified by Advanced Imaging and AI Being able to classify a brain tumor's type, without the use of biopsy, is hard to do; however diffusion weighted imaging, an advanced imaging technique, when combined with machine learning, can help, a study has found Example MR images from paediatric brain tumour patients. This first column shows T1-weighted images following the injection of gadolinium contrast agent. The second column shows T2-weighted images and the final column shows apparent diffusion coefficient maps calculated from diffusion-weighted images. ( a– d– g– i) were acquired from a patient with a Medulloblastoma. Image courtesy of Nature Research Journal
