Cerebral microbleeds (CMBs) was often found in hypertensive patients.Quantitative susceptibility mapping (QSM) could detect iron-containing lesions with high sensitivity and spatial accuracy in the presence of potentially confounding tissue abnormalities.The results of retrospective study showed that there was significant difference in CMBs between the hypertensive group and the control group.So the conclussion is MR quantitative susceptibility could directly explicate the evolution law of CMBs in hypertensive patients, timely intervention of hypertension could reduce the occurrence of CMBs.
