目的探讨磁共振胰胆管成像(MRCP)及MRI在小胰腺癌诊断中的价值。资料与方法回顾性分析经手术病理证实的21例肿瘤最大径≤3.0cm的小胰腺癌患者的MRI及MRCP表现。结果21例小胰腺癌中,脂肪抑制T1WI呈低信号18例,等信号3例;T2WI呈略高信号15例,等信号6例。增强扫描,动脉期所有病灶均表现为不强化或强化不明显低信号;MRCP显示胆总管扩张13例,胰管扩张21例。结论MRCP结合MRI扫描对小胰腺癌的检出和诊断具有重要价值。
Objective To investigate the value of magnetic resonance cholangiopancreatography (MRCP) and MRI in the diagnosis of small pancreatic cancer. Materials and Methods MRI and MRCP findings of 21 patients with small pancreatic cancer whose maximum diameter ≤3.0cm were confirmed by pathology were retrospectively analyzed. Results In 21 cases of small pancreatic cancer, there were 18 cases of low signal of fat suppression T1WI, 3 cases of equal signal; 15 cases of slight high signal of T2WI, 6 cases of equal signal. Enhanced scan, all lesions in the arterial phase showed no enhancement or enhancement is not significantly lower signal; MRCP showed common bile duct dilatation in 13 cases, pancreatic duct dilatation in 21 cases. Conclusion MRCP combined with MRI scan is of great value in detecting and diagnosing small pancreatic cancer.
