目的：探讨可逆性后部脑病综合征的CT、MRI诊断价值。方法复习相关文献并回顾性分析11例可逆性后部脑病综合征的临床和影像学资料。8例行CT平扫，10例行MRI平扫+弥散加权成像，1例行MRI钆喷替酸葡甲胺增强扫描。结果11例表现为大脑后部病变，10例两侧基本对称，1例单侧发生。CT表现为片状低密度影，灰白质交界模糊，皮层变薄，脑沟变浅；MRI表现为脑回样异常信号：T1WI呈等低信号，T2WI及FLAIR呈明显高信号，DWI及eADC呈等低信号，ADC呈等高信号，增强无明显异常强化。结论可逆性后部脑病综合征的CT、MRI表现具有特征性，CT可作为本病的筛选手段，MRI应作为确诊和疗效观察的首选手段。

Objective To explore the diagnostic value of CT and MRI in posterior reversible encephalopathy syndrome (PRES). Methods Review of the relevant literatures and a retrospective analysis on the clinical and imag-ing data of 11 cases of PRES were performed. CT scans were performed in 8 cases, MRI scans and DWI were applied in 10 cases, and MRI Gd-DTPA enhanced scan was used in 1 case. Results 11 cases showed lesions in the back of the brain, 10 showed basic symmetry on both sides, and one showed unilateral lesions. CT showed patchy low density shadow, fuzzy gray and white matter junction, cortical thinning, shallow sulci;MRI showed gyriform abnormal sig-nals: T1WI showed low and equal signal, T2WI and FLAIR showed a significantly high signal, DWI and eADC showed equal and low signal, ADC showed high signal, enhanced no abnormal enhancement. Conclusion CT, MRI appearances of PRES are characteristic. CT can be used as a screening method of the disease, and MRI can be used as the preferred mean for diagnosis and clinical observation.
