起源于垂体前叶的垂体微腺癌是颅内常见肿瘤。MRI与CT相比较，前者软组织分辨力高、多参数、三维成像、无骨伪影等优点，大多数学者认为MRI是目前影像学对垂体微腺瘤诊断的最佳手段，首选方法。但是，由于垂体微腺癌本身病变较小，再加上MRI使用的成像技术、设备性能、窗技术及 Pituitary microadenocarcinoma, originated in the anterior pituitary, is a common intracranial tumor. Compared with CT, the former has advantages of high soft tissue resolution, multi-parameter, three-dimensional imaging, and no bone artifacts. Most scholars believe that MRI is currently the best method for the diagnosis of pituitary microadenomas by imaging, the preferred method. However, due to the small lesions of the pituitary microcarcinoma itself, together with the imaging technology, equipment performance, window technology and the use of MRI
