A rephasing or refocusing, which occurs when constant velocity spins return to the same starting phase they had directly after the initial exciting RF pulse, as a result of the application of an even number of gradient pulses. This may also result from the application of multiple gradient echo pulses following the RF pulse. The even echo rephasing phenomenon is one of the flow effects observed in MR imaging.

From Toshiba America Medical Systems Inc.;
the EXCELART is a superconducting whole body MRI system with a short wide-bore magnet, operating at 1.5 T. It features powerful high-speed gradients with a revolutionary gradient acoustic noise reduction system: Pianissimo. The dramatic reduction of gradient acoustic noise by Pianissimo greatly enhances patient comfort during exams. The standard array platform and a wide range of array coils ensure excellent images. A powerful 64-bit RISC-based computer system and newly developed array processor realize high productivity.

Sent (inducing, transferring) energy into the 'spinning' nuclei via radio frequency pulse, which puts the nuclei into a higher energy state. By producing a net transverse magnetization a MRI system can observe a response from the excited system.

A mathematical algorithm that compensates ghosting caused by breathing.
