Abstract: Objective To investigate the diagnostic value of the texture analysis in differentiating adult pilocytic astrocytomas (PA)from hemangioblastomas(HB).Methods 22 adult patients with PA and 20 patients with HB which were confirmed by postoperative pathological were retrospectively reviewed.The conventional MRI features and texture parameters were analyzed.Eight texture parameters were extracted using run-length matrix(RLM),and the differences of texture parameters of the two groups were analyzed by independent-samples t test.Results The short run emphasis(SRE),grey-level non-uniformity(GLNU),run-length non-uniformity(RLNU),high grey-level run emphasis(HGRE)and short run high grey-level emphasis(SRHGE)were higher in adult PA than in HB.The long run emphasis(LRE),low grey-level run emphasis(LGRE)and short run low grey-level emphasis(SRLGE)were lower in adult PA than in HB.The eight texture parameters had significant differences between the two groups(P<0.05).Conclusion Texture analysis can provide reliably objective basis for differentiating adult PA from HB.
