Study of the correlation between the consistency of pituitary tumor and MR signal intensity
摘要
Abstract
Objective To investigate the relationship between tumor consistency and the intensity of T 2-weighted MR ima-ging signal in patients with pituitary tumors ,and to provide the basis for the prediction of operation risk and operation effect . Methods The clinical data ,imaging findings and operation in 58 cases of pituitary tumor patients in our hospital were analyzed retrospectively .Results The consistency of pituitary tumor and T1 weighted MR imaging signal showed no relationship (P>0.05);T2 WI tumor/white matter signal intensity ratio was significantly associated with tumor consistency (P<0.05). The average tumor texture collagen content was significantly lower in patients with soft texture tumor than that in patients with tough texture tumor ,the difference was statistically significant (P<0.05);while T2 WI tumor/white matter signal intensity ratio in patients with tumor of soft texture was significantly higher than that in patients with tough texture tumor (P<0.05).T2 WI tumor/white matter signal intensity ratio was negatively correlated with tumor collagen content ( r = - 0.794 , P<0.05).Conclusion Pituitary tumors texture determines the extent of surgical resection ;the judgment of tumor texture can predict the operation effect by MR signal intensity. MRI T2WI tumor/white matter signal intensity ratio can be used as an indi-cator to preoperatively assess the consistency of pituitary tumors.关键词
