Abstract

A single-shot echo-planar diffusion imaging sequence (IVIM-EPI: intra-voxel incoherent motion echo-planar imaging) is presented, which is immune from the motion artifacts which may seriously impair images obtained using other diffusion imaging sequences. For a static water phantom, the measured value of diffusion constant ( D = 2.30 × 10 −9 m 2 s −1 at T = 298 K) shows excellent agreement with that obtained using a multipulse spin-echo technique and with literature values. Single-shot diffusion imaging can now be used reliably to make dynamic time-course studies with excellent time resolution.
