Pituitary Tumor MRI Segmentation Dataset

Pituitary adenoma (PA) is one of the most common tumors of the central nervous system, accounting for about 10%-25% of all cases. Although it is generally considered to be a benign tumor, the tumor can compress important tissue structures around it and cause corresponding symptoms. And surgical treatment is the preferred treatment for pituitary adenoma. Therefore, preoperative observation on MRI is important to provide anatomical information to plan the resection and predict the prognosis. However, due to the lack of MRI annotation data of pituitary adenoma, there are limited studies on MRI automatic segmentation of pituitary adenoma through deep learning.
