ABSTRACT:
A method for enhancing the sensitivity of gradient-recalled echo imaging for T2* effects in dynamic magnetic resonance imaging which involves the step of delaying gradient-recalled echoes so that the gradient-recalled echoes are subjected to magnetic susceptibility effects for an extended period of time. The gradient-recalled echoes are delayed beyond a subsequent radio frequency pulse by applying an additional gradient which dephases any gradient-recalled echo of spins that are excited in the radio frequency repetition time period in which said gradient-recalled echoes are produced.
