摘　　要：目的　探讨动态磁共振 (MRI)对库欣病的诊断意义。方法　回顾性分析经临床和实验室检查诊断为库欣病者 32例 ,均行蝶鞍区普通平扫和增强后动态MRI检查。结果　动态MRI诊断垂体腺瘤 2 9例。 32例均行经蝶窦显微外科手术。术后病理报告垂体腺瘤 2 9例 ,垂体细胞增生 2例 ,病理阴性 1例。术后随访 3～ 1 5个月 ,皮质醇下降至正常者 2 8例。结论　动态MRI能更清晰地显示蝶鞍内垂体微小腺瘤 ,可提高垂体微腺瘤的诊断率。Objective To study the diagnostic value of magnetic resonance image (MRI) in Cushing's disease.Methods In this retrospective study,32 patients with Cushing's diseases diagnosed by clinical presentation and laboratory examination were reviewed.All patients had taken traditional MRI (plain and contrast MRI) and dynamic MRI.29 adenomas were discovered by dynamic MRI.Transsphenoidal surgery was performed on all patients.The pituitary adenomas were diagnosed by pathological examination in 29 cases,pituitary hyperplasia in 2 cases and negative in pathologic examination in 1 case.Results All the patients were followed postopertatively from 3 to 15 months.The urinary free cortisol (UFC) and plasma cortisol returned to normal in 28 cases.Conclusions Dynamic MRI can show pituitary microadenomas clarely and therefore can improve the detection rate of pituitary microadenomas.
