Abstract

Changes in the local magnetic susceptibility of brain tissue due to injected paramagnetic contrast agent are manifest as both a line-broadening and frequency shift of the water resonance. By combining these two effects, the sensitivity of gradient recalled echo images to such changes can be increased.

摘要

注射的顺磁性造影剂导致脑组织局部磁敏感性的变化表现为水共振的线展宽和频率偏移。通过结合这两种效应,可以提高梯度回波图像对此类变化的敏感性。
