摘　　要：目的:探讨高场强MRI在胰腺癌中的诊断价值。方法:收集本院经手术病理和/或临床、影像检查证实的胰腺癌18例,均作了MRI FSPGR序列非抑脂T1WI和抑脂T1WI平扫及动态增强扫描以及磁共振胰胆管成像(MRCP),分析其MRI及MRCP表现。结果:18例胰腺癌中,非抑脂T1WI呈低信号12例,等信号6例;抑脂T1WI呈低信号15例,等信号3例,动态增强扫描,动脉期所有病灶均表现为不强化或强化不明显呈低信号;MRCP显示胆总管扩张12例,胰管扩张12例,“双管征”8例。结论:高场强MRI对胰腺癌的检出和诊断具有重要价值。Objective： To investigate the value of diagnosing pancreatic carcinoma（PC） with high field MRI, Methods： 18 cases with PC proved by surgico-pathology and/or clinic and imaging data were underwent T1WI with or without fat suppression, dynamic contrast enhanced FSPGR sequence and MRCP technique with high field MRI. Results： Of all 18 cases, on T1WI the lesions showed hypo-intensity in 12,iso-intensity in 6 cases, while on T1WI with fat suppress the lesions appearead hypo-intensity in 15, iso-intensity in 3 cases. With dynamic contrast-enhanced FSPGR sequence all lesions showed hypo-intensity without or with only slight enhancement during arterial phase scanning. MRCP depicted dearly dilated common bile duct in 12 cases, dilated pancreatic duct in 12 cases and ＂double-duct sign＂ in 8 cases of all 18 cases. Conclusion： High field MRI examination could play an important role in detecting and diagnosing PC.
