The key to thrombolytic therapy in acute ischemic stroke
is identifying the areas of infarct lesion in acute
stage. By using a prototype simultaneous multi-slice
accelerated (SMS) EPI sequence for DKI data recording,
the total acquisition time could be cut down to 1/2~1/3
of standard EPI-based DKI without losing SNR. In the
identification of the final infarct size in acute
ischemic stroke, the volume measurements by SMS DKI in
the acute-phase is more reliable than that of ADC, and
the DKI data could be acquired in a reasonable time with
the SMS EPI sequence.
