Methods and materials

63 patients with postoperative glioblastoma (GB) were examined on 1.5T-MRI with multiparametric protocol before the radiotherapy (RT), after 1 month, 3 months and 6 months after completing radiotherapy course. Protocol included T2W, T1W, FLAIR, DWI, SWI, ASL, DSC-perfusion and contrast-enhanced 3DT1W.

Invasion of CP was concluded by detection of feeding arteries and drainage veins on SWI and contrast-enhanced T1W as well as hyperperfusion in the region of interest by ASL and DSC perfusion methods. Period of 6 months after radiation or chemoradiation treatment was selected as a reference assessment line.

Kendall tau-b coefficient and cross tabulation were used for statistical analysis.
