Sources have it that the incidence rate of intracranial gliomas postoperative reactional enhancement is 65.7%(134/204), whereas that of tumor residual is 34.3%(70/204) [1]. The network is capable of learning and memorizing, and can memorize the data diffusion features. Therefore, if data with such rates are employed to train the network, it will overstudy reactional enhancement. Even though the network training is not successful and all are diagnosed as reactional enhancement, the correctness will be still as high as 65.7%.
