Abstract:
Objective To observe and measure the morphology of diaphragm sella under MR imaging and its parameters in patients with pituitary adenoma,and to explore its clinical significance.Methods Forty-seven patients with pituitary adenoma,admitted to our hospital from March 2012 to April 2013,were collected in our study; the traditional MR imaging of all patients were obtained preoperatively and postoperatively,and 3D-GE sequence scanning was added preoperatively.The parameters of diaphragm sella were measured and compared between patients existed invasion and without invasion,and between patients enjoyed total resection and non-total resection; and the correlation between each two parameters were analyzed.Results Concave,horizontal and convex diaphragm sellae (n=3,10 and 34,respectively) were observed; tumor height of the patients whose diaphragm sella was convex was significantly higher than that of the concave cases ([28.82±11.29] mm vs.[13.57±4.42]mm,P＜0.05).The size and elevation angle of the diaphragmal opening were positively correlated with tumor height (r=0.224,P=0.003; r=0.586,P=0.000).The size ofdiaphragmal opening in the invasive group was significantly larger than that in non-invasive group ([10.30±5.79] mm vs.[5.55 ±3.29] mm,P=0.002).The size of diaphragmal opening in non-total resection group was significantly greater than that in the total resection group ([5.58±4.14] mmvs.[11.04±4.80] mm,P=0.000),and the width of diaphragrnal opening was negatively correlated with tumor resection ratio (r=-0.576,P=0.020).Conclusions Diaphragrna sellae could be displayed satisfactorily in contrast-enhanced 3D-GE MRI.The size of the diaphragmal opening and the elevated angle of drua besides diaphragrnal opening are positively correlated with tumor height.The size of diaphragmal opening of the invasive pituitary adenoma patients is larger than that ofnon-invasive ones.The larger the diaphragrnal opening size,the more difficult the tumor being totally resected by transsphenoidal approach.
