Background Deep‐learning is widely used for lesion classification. However, in the clinic patient data often has missing images.
Purpose To evaluate the use of generated, duplicate and empty(black) images for replacing missing MRI data in AI brain tumor classification tasks.
Study Type Retrospective.
Population 224 patients (local‐dataset; low‐grade‐glioma (LGG) = 37, high‐grade‐glioma...
