Abstract

Excitation by conventional B1 pulses in surface coil chemical-shift imaging experiments yields resonance intensities that vary greatly with position. B1-compensated semi-selective pulses overcome much of this problem. These pulses are employed for excitation and refocusing in 1H NMR spectroscopic localization in the intact heart.

摘要

在表面线圈化学位移成像实验中，传统B1脉冲激发产生的共振强度会随位置发生很大变化。B1补偿半选择性脉冲很大程度上克服了这个问题。这些脉冲用于完整心脏的1H NMR波谱定位中的激发和重聚焦。
