Synopsis

Diffusion-relaxation matrix (DRM) sequence consists of dual-echo single-shot DW-EPI. DRM was able to detect acute cerebral infarction as well as conventional DWI, and can simultaneously acquire ADC and T2 values. T2 values in the infarcted area correlated significantly with time since stroke onset, whereas ADC did not. In addition, T2 values could predict whether the infarct was within 4.5, 6, or 16 hours, which are the thresholds for thrombolysis and endovascular treatment.
