目的探讨不同病理分级原发性肝脏神经内分泌肿瘤患者的核磁共振成像表现.方法对11例原发性肝脏神经内分泌肿瘤患者的临床一般资料、核磁共振成像检查、病理检测结果进行回顾性分析.结果本组11例患者中共发现16个病灶;病理G1级3例、G2级5例、G3级2例;G1级患者病灶信号相对均匀,T1WI呈稍低信号,T2WI呈稍高信号;G2级患者病灶表现为T1WI不均匀稍低信号,部分病灶内可见不规则稍高信号,T2WI呈不均匀稍高信号,有6个病灶内可见高低信号分层影,所有病灶均可见T2高信号影;G3级患者病灶表现为T1WI以不均匀低信号为主,T2WI呈不均匀稍高信号,均可见T2高信号影;病理G2级、G3级病灶出现T2高信号影的概率均为100%,显著高于G1级(P<0.05或0.01);病理G2级病灶出现高低信号分层影概率为75.0%,显著高于G3级病灶(P<0.05).结论不同病理分级原发性肝脏神经内分泌肿瘤患者的核磁共振成像表现具有一定的特征性,在诊断中有一定应用价值.
Objective To investigate the MRI manifestation of PHNET paticenls with different pathological grades.Methods The clinical data,MRI examination and pathological examination results of 11 PHNET patients were retrospectively analyzed.Results 16 lesions were found in 11 patients,3 patients with grade.G1,5 patients with G2,and 2 patients with G3.The lesions signal of the G1 patients was relatively uni-form,the T1WI was slightly lower signal and the T2WI was slightly higher.The T1WI in lesions of the patients with grade G2 were inhomogeneous and slightly low signal,and the irregular and slightly high signal was found in some lesions.T2WI showed uneven and slightly high signal,6 lesions had high and low signal stratification,and T2 high signal was found in all lesions.The T1 WI in lesions of the patients with grade G3 were inhomogeneous and low signal,and the T2WI was uneven and slightly high signal,and the T2 high signal was found in all lesions.The proportion of T2 high signal in pathological G2 and G3 lesions was 100%,which were significantly higher than that in G1 patients(P<0.05 or 0.01).The pro-portion of high and low signal stratification in pathological G2 lesion was 75%,which was significantly higher than that of G3 lesion(P<0.05).Conclusions The MRI performance of PHNET patients with different pathological grades has certain characteristics and has certain application value in diagnosis.
