摘要
目的探讨肝脏孤立性坏死结节(SNN)的CT、磁共振成像(MRI)影像学表现与病理基础。方法将34例SNN患者随机分为两组:CT组17例,行CT检查;MRI组17例,行MRI检查。观察两组患者的影像学表现,总结SNN的病理基础,分析CT和MRI的诊断价值。结果手术共确诊单纯凝固性坏死型病例18例,伴液化坏死性7例,多结节融合型13例;CT分别确诊9例、4例和6例;MRI扫描分别确诊13例、3例和8例。MRI扫描方法在单纯凝固性坏死、多结节融合SNN病理类型判断方面优于CT扫描(P<0.05)。结论 CT、MRI均为诊断SNN的常用方法,在多结节融合型和伴液化坏死型SNN诊断方面,MRI的诊断效果明显优于CT。
：Objective To investigate CT, MRI liver solitary necrotic nodule （SNN） imaging findings andpathological basis. Methods 34 SNN cases were randomly divided into two groups CT group of 17 cases, MRI group of 17 cases. Imaging findings of the two groups were observed,the pathological basis of SNN was summarized and the diagnostic value of CT and MRI was analyzed. Results ：Surgery cotifirmed a total of 18 cases of simple coagulation necrosis of cases,7 cases with liquefaction necrosrs, the multinodular fqsion 13 cases. CT,confirmed 9 cases,4 cases and 6 eases respectively. MRI scan confirmed 13 cases,3 cases and 8 cases respectively. MRI scans is superior to CT scan（ P 〈 0.05 ） in simple coagulation necrosis, multiple nod- ules fusion SNN pathological type judgment. Conclusion CT and MRI are common diagnostic method of SNN, and MRI has significantly better performance than CT in multi-nodular type and liquefaction .necrosis SNN diagnosis.
