摘　　要：目的：探讨脑功能核磁共振成像（ Magnetic Resonance Imaging，MRI）与磁共振弥散加权成像（Diffusion Weighted Imaging, DWI）联合应用在妊娠高血压综合征致脑后部可逆性脑病综合征的临床价值。方法：选取2015年1月-2017年-12月收治的31例妊娠期高血压综合征患者作为观察对象。患者均发生后部可逆性脑病综合征，采用核磁共振成像与磁共振弥散加权成像进行诊断，观察成像结果。结果： 首次病灶表现病变部位主要包括两侧额顶枕叶皮层区、皮层下白质区、小脑半球、侧脑室等部位。DIW图现呈现等信号或者低信号、等信号以及高信号。T1W2像上病灶多为呈高信号。T1W1像上病灶显示为等或略低信号。经过降压 、解痉及及时终止妊娠等治疗措施，患者均得到了有效抢救。结论：利用核磁共振血管成像技术可有效诊断妊娠高血压综合征致脑后部可逆性脑病综合征，为临床尽早干预治疗提供可靠依据，诊断价值突出，值得临床推广。0bjective： To investigate the clinical value of combined use of magnetic resonance imaging （MRI） and diffusion weighted imaging （DWI） in the diagnosis of pregnancy-induced hypertension. Methods：Thirty-one patients with gestational hypertension syndrome who were admitted from January 2015 to 2017 to December 2015 were selected for observation. All patients developed posterior reversible encephalopathy syndrome and were diagnosed by magnetic resonance imaging and diffusion-weighted imaging. The imaging results were observed. Results： The lesions on the first lesion were mainly composed of bilateral frontal occipital cortex, subcortical white matter, cerebellar hemisphere and lateral ventricle. The DIW diagram now presents equal signals or low signals, equal signals, and high signals. Most of the T1W2 lesions showed high signal. T1W1 appears as equal or slightly lower signal on the lesion. After termination of pregnancy, blood pressure and other treatment measures have been effectively rescued patients. Conclusion： The use of nuclear magnetic resonance angiography for the diagnosis of gestational hypertension can provide a reliable basis for clinical intervention as soon as possible. The diagnostic value is outstanding and worthy of clinical promotion
