Echo planar imaging is the acquisition of multiple echoes following the 90° / 180° in a spin-echo sequence. Each subsequent echo results in a progressively T2-weighted signal. As a result an image can be acquired in 20 - 100 msec, allowing excellent temporal resolution such as that required in cardiac imaging.
