The Diagnosis Value Of Susceptibility Weighted Imaging Semiquantitative Assessment For Pathological Vasculairity In Grading Cerebral Glioma

Objective To investigate the diagnosis value of susceptibility weighted imagingsemiquantitative assessment for pathological vascularity in grading cerebral gliomas.Methods Thirty-six patients with gliomas(15low-grade and21high-gradegliomas)were imaged before therapy.Standard clinical MR imaging and SWI were performedan a GE3.0T scanner. All SWI postprocessed images were reviewed independently by twoneuroradiologists and the number of vessels in tumor region were scored.Tumor were gradedaccording to the World Health Organization classification.Results15cases of low-grade glioma,semiquantitative assessment of pathologicalvascularity scored0in6cases,1in9cases.21cases of high-grade gliomas,semiquantitative assessment of pathological vascularity scored2in18cases,3in2cases,1in1case. There was a statistically significant association between low-grade and high-gradegliomas(Z=-5.327,P<0.05).The grade of intratumoral pathological vascularity detected onSWI was associated with tumor grade.Conclusion It is usefull that susceptibility weighted imaging semiquantitativeassessment of pathlogical vascularity in grading cerebral gliomas between low-grade andhigh-grade.
