The results of 165 clinical examinations of the brain in which phase mapping was used to display susceptibility effects have been analysed. Significant changes were frequently observed when hemorrhage was a primary or secondary event. A substantial fraction of the examinations, including those of tumor, trauma, hemorrhage, and other patients, showed changes of up to 1 ppm. Spectral interpretation may be made more difficult in many clinical circumstances by susceptibility effects.
对165例脑部临床检查结果进行了分析，这些检查使用相位映射来显示磁化率效应。当出血为主要或次要事件时，经常观察到显著变化。包括肿瘤、创伤、出血及其他患者在内的很大一部分检查显示变化高达1 ppm。在许多临床情况下，磁化率效应可能会使频谱解释变得更加困难。
