Abstract
Objective:To evaluate the correlation between the cerebral microbleeds and the blood pressure. Materials and Methods:A total of 524 subjects were carried out conventional sequences of T1 weight imaging (T1WI), T2 weight imaging (T2WI), FLAIR, DWI and susceptibility weighted imaging (SWI). The brain regions, number and grades of the CMBs were analyzed. The hypertension history, blood pressure values before MR examination were recorded. The blood pressure level of the subjects were divided into different grades. The subjects were divided into two groups:CMBs group and non CMBs group. Then we compare the differences of gender, age, hypertension period (year), the prevalence rate of hypertension, high blood pressure level, the average systolic pressure, diastolic pressure and CMBs sites between the two groups.The correlation between CMBs and the age, blood pressure grade, Systolic Bp and Diastolic BP was analyzed. Results:The hypertension prevalence, the average systolic blood pressure and the diastolic blood pressure of CMBs group were higher than those of values in non CMBs group. There is a longer hypertension period in CMBs group compared with non CMBs group. The CMBs distribution of different areas had significant difference. The grades of CMBs were correlated with the age, blood pressure grade, Systolic Bp and Diastolic BP. Conclusions:There was signiifcant correlation between the CMBs and hypertension.关键词
