Predictive value of PWI for blood supply and T1-spin echo MRI for consistency of XXXX .

@entity1 @entity5 @entity4611 @entity977 @entity1758
INTRODUCTION: It is a common view that consistency and blood supply of @entity977 ( @entity977 ) can influence the surgical effect. The aim of this study was to determine whether MRI signal intensity (SI) was correlated to the consistency or blood supply of @entity4611 . METHODS: Forty eight @entity4611 @entity1 were underwent preoperative MRI, including precontrast and contrast-enhanced (CE) T1-spin echo (T1-SE) imaging, CE-sampling perfection with application-optimized contrasts by using different flip angle evolutions (SPACE) imaging, and perfusion-weighted imaging (PWI). The @entity5 consistency and blood supply were determined by neurosurgeons. The expression of collagen IV and @entity1758 was detected with immunohistology. The correlation of the relative SI (rSI) values ( @entity5 to normal frontal white matter SI) and PWI data to the @entity5 consistency, blood supply, and the expression level of collagen IV and @entity1758 was statistically studied by Kruskal-Wallis rank test (K-W test). RESULTS: A significant correlation was observed between the @entity5 consistency and the rSI on precontrast T1-SE imaging (P   =   0.004) but not on CE T1-SE and CE SPACE imaging. The expression of collagen IV was also significantly associated with rSI on T1-SE imaging (P   =   0.010). The blood supply was correlated with the relative CBV (rCBV) (P   =   0.030). In addition, the expression of @entity1758 was correlated with rSI of CE T1-SE imaging (P   =   0.007). CONCLUSION: Our results suggest that T1-SE imaging may be a simple and useful method for predicting consistency of @entity977 . CBV value can provide helpful information for assessing the blood supply of @entity4611 .
