摘要目的80%~85%内源性库欣综合征是由位于垂体的微腺瘤分泌促肾上腺皮质激素(ACTH)增多引起,该病的确诊需要依据中央静脉采样和MRI,垂体源性的库欣综合征治疗原则为外科手术,因此能够高分辨显示垂体结构及病变的MRI至关重要,该研究采用7.0 T与1.5 T MRI对16例确诊为库欣病病人的垂体影像进行比较分析,以评估两者对垂体微小病变的检出能力。材料与方法 16例病人先后进行 Abstract Objective 80% ~ 85% of endogenous Cushing’s syndrome is caused by the secretion of adrenocorticotropic hormone (ACTH) secreted by the pituitary adenoma. The diagnosis of this disease needs to be based on central venous sampling and MRI, The principle of Xin syndrome treatment for surgery, so high resolution display of pituitary structure and lesions of the MRI is crucial, the study using 7.0 T and 1.5 T MRI in 16 patients diagnosed as Cushing’s disease in patients with pituitary images were compared to analyze Evaluate the ability of both to detect small pituitary lesions. Materials and Methods 16 patients have carried out
