Materials and Methods MRH was performed in 119 patients , including 93 cases of MR cholangiopancreatography ( MRCP ) and 26 cases of MR urography ( MRU ) .

材料与方法收集临床拟诊为胆道和尿路梗阻行MRH检查者119例，其中MR胰胆管成像（MRCP）93例，MR尿路成像（MRU）26例。

Result The morbidity rate of hypertension ( MRH ) in rural residents was 17.69 % . The aged-standardized MRH was 14.01 % .

结果清远市石灰岩地区农村居民高血压总患病率为17.69%，标化患病率为14.01%。

Combining with MR axial pictures and MRH source images , the accuracy of MRCP and MRU for demonstrating the cause of obstruction was 91.4 % and 80.8 % , respectively .

结合MR断面图像与MRH原始影像，MRCP对胆道梗阻的定性诊断准确性为91.4%，MRU对尿路梗阻的定性诊断准确性为80.8%。

The increase of MRH was correlated with the increase in age . The risk factors of hypertension were alcohol consumption , high body mass index ( BMI ), high waist and hip ratio ( WHR ), workload , psychology factor ( e.g. stress ) .

高血压患病率随年龄增长呈增高趋势，农村居民高血压危险因素为饮酒、吸烟、劳动强度大、精神心理因素（如精神紧张）、高体质指数（BMI）、高腰臀比（WHR）等。
