摘　　要：目的 探讨睾丸扭转的MRI特征，以提高临床及影像学认识。方法 收集8例经手术病理证实的睾丸扭转临床及影像学资料，并结合手术大体病理进行总结分析；8例患者，其中2例行MRI平扫，6例行MRI平扫＋增强扫描。结果 8例睾丸扭转患者中位年龄16.7岁，发病时间4.0～24.0 h。6例（75.0%）MRI表现为睾丸及附睾体积增大，2例（25.0%）睾丸T1WI序列信号增高，4例（50.0%）睾丸T2WI序列信号降低， 8例（100.0%）精索增粗、扭曲并见结节，6例（75.0%）患侧睾丸及附睾强化减退或无强化。结论 精索增粗、扭曲，睾丸及附睾强化减退或消失是睾丸扭转较为特征的MRI表现。Objective To discuss the MRI features of testicular torsion,and to improve the clinical and imaging understanding. Methods 8 cases of testicular torsion confirmed by surgery and pathology were included in this study,the MRI signs and clinical data were compared and analyzed.2 underwent MRI conventional scan, 6 underwent both MRI conventional and enhanced scan.Results The median age of testicular torsion male patients was 16.7 years, attack time 4.0-24.0 h. In MRI, there were 6 cases（ 75.0 %）with testis and epididymis volume augmented,2 cases（25.0%）with increase of testicular signal strength in T1WI sequence, 4 cases（50.0 %） with decrease of testicular signal strength in T2 WI sequence, 8 cases （ 100.0%） with tortuosity, enlargement, nodules of spermatic cord,6 cases（75.0%） with decreased enhancement in testis and epididymis.Conclusion Tortuosity, enlargement of spermatic cord and decreased enhancement in testis and epididymis are the MRI features of testicular torsion.
