In this section, the radiological findings of brain tumors have been discussed, along with case examples. The importance of MRI, which is the fundamental radiological modality in the diagnosis of brain tumors, is increasing day by day. The continuous development of advanced MRI techniques allows for a safer diagnosis of these tumors with each passing day. Providing accurate information about the tumor to neurosurgeons performing surgical treatment of brain tumors, radiation oncologists performing radiotherapy, and medical oncologists performing medical treatments has become increasingly important, and the level of knowledge about conventional and advanced neuroradiological techniques has become crucial.
