Abstract

Objectives

T2’ values reflect the presence of deoxyhaemoglobin related to high local oxygen extraction. We assessed the feasibility of T2’ imaging to display regions with high metabolic activity in brain gliomas.

Methods

MRI was performed in 25 patients (12 female; median age 46 years; range 2–69) with brain gliomas with additional T2 and T2* sequences. T2’ maps were derived from T2 and T2*. Dynamic susceptibility weighted contrast (DSC) perfusion was performed in 12/25 patients. Images were visually assessed by two readers and five ROIs were evaluated for each patient. Pearson correlation, Mann–Whitney and Kruskal–Wallis tests were applied for statistical analysis.

Results

Three patients were not further evaluated because of artefacts. Mean values of high-grade (III–IV) gliomas showed significantly lower T2’ values than low-grade (II) gliomas (p < 0.001). An inverse relationship was observed between rCBV and sqr (T2’) (r = −0.463, p < 0.001). No correlation was observed between T2’ and rCBV for grade II tumours (r = 0.038; p = 0.875).

Conclusions

High-grade tumours revealed lower T2’ values, presumably because of higher oxygen consumption in proliferating tissue. Our results indicate that T2’ imaging can be used as an alternative to DSC perfusion in the detection of subtle deviations in tumour metabolism.
