Synopsis

We perform a prospective test-retest repeatability study of one such approach, in patients with high-grade glioma. Two separate scans were performed within 3-7 days apart. Tumor, scalp, normal white matter, pons, cerebellum and muscle regions were segmented manually. The coefficients of variation of median Kt were 50.4% to 66.6% and of median vp were 23.2% to 80.0%, based on our first 5 subjects.
