摘　　要：目的 探讨计算机断层扫描(CT)和磁共振(MRI)对先天性成人多囊肾病(ADPKD)的诊断价值。方法 选取2017年1月至2020年3月本院确诊的先天性成人多囊肾病患者74例,所有患者均采用CT与MRI进行检测,以穿刺组织活检或手术结束后,以病理诊断结果 为金标准,比较两组CT、MRI影像学表现与诊断结果 。结果 ADPKD患者肾脏CT影像结果 表现为宽径范围为7.10cm~8.93cm,长径范围为16.64cm~22.07cm,平均CT值为(7.45±1.33)HU;钙化33例,结石9例,出血5例,合并多囊肝14例;MRI检查显示TWI呈低信号,TWI呈高信号时,存在数量不一、大小不等的不规则囊肿性信号影;TWI与TWI呈等信号时,囊肿壁边界清晰,肾区未有正常肾盂结构;CT与MRI联合检测的阳性检出率与灵敏度显著高于CT、MRI单项检测(P<0.05),CT与MRI联合检测的漏诊率显著低于CT、MRI单项检测(P<0.05)。结论 CT结合MRI对ADPKD具有更为精准的诊断,能反映出患者肾实质与其他器官的受累程度,囊肿直径,钙化、结石、出血情况,可作为ADPKD早期诊断的有效方法 。Objective To explore the diagnostic value of computed tomography(CT) and magnetic resonance imaging(MRI) in adult dominant polycystic kidney disease(ADPKD).Methods A total of 74 patients who were confirmed with ADPKD in the hospital from January 2017 to March 2020 were enrolled.All were detected by CT and MRI.After the biopsy or surgery for punctu re tissues,taking pathological diagnosis results as the golden standard,imaging findings and diagnosis results of CT and MRI were compared between the two groups.Results CT imaging results of ADPKD patients showed that renal wide diameter range,long diameter range and mean CT value were 7.10 cm~8.93 cm,16.64 cm~22.07 cm and(7.45±1.33) HU,respectively.There were 33 cases with calcification,9 cases with stones,5 cases with hemorrhage and 14 cases with polycystic liver.MRI examination showed that when TWI showed low signal and TWI showed high signal,there were irregula r and cystic signal shadows of different quantity and size.When TWI and TWI showed equal signal,boundary of cyst wall was clea r,and there was no normal renal pelvis structure in renal area.The positive detection rate and sensitivity of CT combined with MRI were significa ntly higher than those of CT and MRI alone(P<0.05),while whose missed diagnosis rate was significantly lower than that of CT and MRI alone(P<0.05).Conclusion CT combined with MRI can more accurately diagnose ADPKD,which can reflect the involvement degree of renal parenchyma and other organs.Cyst diamete r,calcification,stones and hemorrhage status can be applied as effective methods for early diagnosis of ADPKD.
