摘要
目的:研究空蝶鞍综合征的MRI特征并比较其垂体及垂体柄径线与正常志愿者间有无差异,以判断鞍区压力增高对垂体及垂体柄各径线有无影响。材料与方法:回顾性分析30例女性空蝶鞍综合征患者及30例正常垂体MR图像,测量其垂体上下径、前后径、左右径、垂体柄高径、直径、垂体柄与水平线成角并对各径线进行比较,分析有无差异性。结果:空蝶鞍综合征患者MR图像显示鞍区扩大,鞍内充填脑脊液,垂体受压,体积缩小,垂体柄偏移、拉长。空鞍综合征患者与正常志愿者垂体左右径、垂体前后径、垂体上下径、垂体柄高径、直径及垂体柄与水平线成角之间均有显著性差异(P<0.01)。结论:鞍区压力增高对垂体及垂体柄各径线均有影响,MRI清晰地显示蝶鞍区垂体的形态及毗邻关系,准确测量其相关径线,是空蝶鞍综合征的最佳影像诊断手段,具有广阔的应用前景。
Purpose： To investigate the magnetic resonance imaging （MR.I） character of empty sella syndrome （ESS） and compare with normal volunteers of pituitary in distance of pituitary and stem, in order to estimate effect on press of Ess. Materials and Methods： MPd of 30 ESS and normal volunteers of pituitary compared with distance FH and AP and BL of pituitary and FH and A of stem and angle between stem and horizontal line in order to analyze their othemess. Results： all MPd of 30 ESS showed distensible selh, filled cerebrospinal fluid in selh, pressed and reduced pituitary, excursion and elongate stem. The distance was prominenced discrepancy between ESS and normal volunteers （p 〈 0.01. Conclusion： Distance of pituitary and stem were infection by pressed seUa, MPd distinctly showed form and contiguity of pituiary, measured distances it was best image methods about ESS.
