A detailed evaluation of the MR appearance of the pituitary gland-cavernous sinus junction has not been described. In a series of coronal T1-weighted spin echo images without and with IV gadolinium, we noted the variable size and signal intensity of cavernous venous spaces adjacent to the pituitary gland and the inconsistent visualization of the dural membrane just lateral to the gland. Correlation of coronal T1-weighted spin echo and gradient recalled echo images (the latter with high-signal-intensity vascular structures) proved to be an effective means of identifying cavernous venous spaces, connective tissue and cranial nerves, and the lateral margins of the pituitary gland, and of differentiating tumor tissue from cavernous venous spaces. Further work is needed to develop criteria to distinguish cavernous sinus compression from actual tumor invasion.
尚未有人对垂体-海绵窦交界处的磁共振成像表现进行详细评估。在一系列未注射和注射静脉钆对比剂的冠状位T1加权自旋回波图像中，我们注意到垂体旁海绵状静脉间隙大小和信号强度各异，且紧邻垂体外侧的硬膜显示不一致。冠状位T1加权自旋回波图像与梯度回波图像（后者显示高信号强度血管结构）相结合，被证明是识别海绵状静脉间隙、结缔组织和颅神经以及垂体外侧缘，并区分肿瘤组织与海绵状静脉间隙的有效方法。需要进一步开展工作以制定区分海绵窦受压与实际肿瘤侵犯的标准。
