| 摘 要： | 目的探讨胰腺神经内分泌肿瘤的影像特征。方法分析43例经手术后病理证实的胰腺神经内分泌肿瘤的CT和MRI资料,并与手术病理结果对照。结果 43个病灶平均大小为(25.00±1.82)mm,23个病灶出现坏死囊变;CT平扫15个病灶呈等密度,28个病灶呈稍低密度;43个病灶T1WI均呈低/稍低信号,27个病灶T2WI呈高/稍高信号,16个病灶T2WI呈等信号;26个病灶见包膜;30个病灶显示清晰轮廓;24个病灶增强扫描动脉期病灶即明显强化,8个呈延迟强化,5个呈向心性强化,6个呈轻度强化。结论胰腺神经内分泌肿瘤形态及CT和MRI动态增强扫描具有特征性表现,影像学检查对诊断其具有重要价值。

| Abstract: | Objective To demonstrate the imaging characteristics of pancreatic neuroendocrine neoplasm (P-NEN). Methods The CT and MRI findings of 43 cases of P-NEN confirmed by pathology were analyzed, and compared with pathological results.Results Mean size of 43 lesions in 43 P-NEN patients were (25.00±1.82)mm. Necrosis cystic degeneration were found in 26 lesions. In CT plain scan, 15 lesions were isodense, 28 lesions were hypodense. All of 43 lesions were hypointensity signal on T1WI; 27 lesions were hypointensity signal, 16 cases were isointensity signal on T2WI. Twenty-seven lesions showed envelope; 30 lesions showed clear outline. In enhancement images, 24 lesions were marked enhancement since arteria1 phase; 8 lesions showed delayed enhancement; 5 lesions showed centrality enhancement; 6 lesions showed wild enhancement. Conclusion P-NEN has some characteristics on CT and MRI scanning, imaging can play an important role in diagnosis for P-NEN. |
