METHOD TO ENHANCE THE SENSITIVITY OF MRI FOR MAGNETIC SUSCEPTIBILITY EFFECTS

摘要

method of increasing the sensitivity of the imaging gradient echo t2 * effects recall in a magnetic resonance imaging system, the process of delay gradient recall echo so that they are longer, the effect of magnetic susceptibility.the gradient echoes in recall is delayed beyond a high-frequency pulse) by applying a gradient recalled echo with additional gradient phasing on his spins are excited during the period of repetition frequency at which lesd its response to background gradient is produced.
