Brain MRI Images (Tumor and No Tumor)

This dataset comprises primary clinical MRI scans acquired directly from the Department of Radiology at Dhaka Medical College Hospital (DMCH). It encompasses four diagnostic categories: Glioma, Meningioma, Pituitary, and No Tumor, representing real-world imaging scenarios with authentic scanner noise and contrast variations. All samples have undergone strict anonymization (PHI removal) and rigorous pre-processing, including cropping, color grading, image enhancement and resize. This collection is uniquely suited for evaluating Deep Learning model performance on raw, single-source clinical data distinct from standard public benchmarks.
