Table 1 4DST PET and MRI parameters in patients with newly diagnosed gliomas

From: Correlation of 4′-[methyl-11C]-thiothymidine PET with Gd-enhanced and FLAIR MRI in patients with newly diagnosed glioma

Parameter All patients (n = 23) Glioblastoma (n = 14)
Median volume in cm3
 PTV (range) 14.47 (0–66.79) 23.94 (2.03–66.79)
 GdV (range) 6.79 (0–84.35) 31.05 (3.35–84.35)
 FLAIRV (range) 50.10 (11.02–196.16)* 112.45 (11.02–196.16)*
  1. PTV Proliferative tumor volume, GdV volume of Gd enhancement, FLAIRV volume of hyperintense FLAIR
  2. *P < 0.001 compared with PTV
