Does mR cerebral blood volume map correlated with vascular endothelial growth factor expression and tumor grade in nonenhancing gliomas?
Our results confirmed the correlation among rCBV measurements, VEGF expression, and histopathologic grade in nonenhancing gliomas. PWI may add useful data to the preoperative assessment of nonenhancing gliomas. Its contribution in predicting tumor behavior and patient prognosis remains to be determined.
Approximately 50% of UT specimens with LGUN on follow-up demonstrated atypical features. Based on comparison with benign UW controls, TFs, cytoplasmic tails, nuclear eccentricity, and enlarged nuclei were more pronounced in neoplastic UW than VU specimens, suggesting that the method of urine specimen procurement affects the presence of certain low-grade features.
