In this study, we evaluated the usefulness of dynamic studies for the preoperative diagnosis of tumor lesions adjacent to the pituitary gland. We examined 13 tumors. We obtained pre- and post-contrast thin slice T1-weighted images of the sellar regions. FSE sequences were used for dynamic study. The capability to distinguish the tumor from the pituitary gland and additional information obtained from the dynamic study were evaluated. Two meningiomas were identified more clearly on the dynamic than on the delayed study. In two cavernous hemangiomas, the peripheral nodular stains gradually increased during the dynamic study. For the preoperative evaluation of lesions adjacent to the pituitary gland, the dynamic study can often identify the lesions more clearly and may provide additional information.
在本研究中，我们评估了动态研究对垂体旁肿瘤病变术前诊断的实用性。我们检查了13个肿瘤。我们获取了鞍区对比剂注射前后的薄层T1加权图像。采用快速自旋回波序列进行动态研究。评估了区分肿瘤与垂体的能力以及从动态研究中获得的额外信息。2例脑膜瘤在动态研究中比延迟研究中显示得更清晰。2例海绵状血管瘤在动态研究过程中外围结节状强化逐渐增加。对于垂体旁病变的术前评估，动态研究通常能更清晰地识别病变，并可能提供额外信息。
