摘要：

An interesting pulse sequence of 90°-τ-180°-2τ-180°-τ which leads to a signal suppression for the static samples is reported. With this sequence we have obtained static-sample signal suppression of the order of 10-4 to 10-6 and the results obtained suggest a wide range of applications, such as MR angiography. This observation has been explained theoretically, based on the steady-state equation of the composite sequence. Experimental verification has been performed using the KAIS 2.0 T NMR imaging system. © 1990.
