目的 了解磁共振动态增强和脂肪抑制技术在胰腺癌诊断中的价值。材料与方法 18例经手术病理证实的胰腺癌患者进行了磁共振检查 ,采用的磁共振序列分别为 :SET1WI、FSET2 WI、脂肪抑制技术SET1WI和动态增强FMPSPGR等。结果 18例胰腺癌肿瘤病灶 ,在SET1WI上呈低信号者 10例 ,等信号者 6例 ,高信号者 2例 ;FSET2 WI上高信号者 8例 ,等信号者 6例 ,低信号者 4例 ;脂肪抑制技术SET1WI上所有肿瘤均呈低信号改变 ,同时在动态增强FMPSPGR动脉期扫描 ,所有肿瘤均表现为强化不明显或不强化而呈低信号。结论 脂肪抑制技术SET1WI和动态增强FMPSPGR能够明显提高胰腺癌诊断的敏感性和特异性。
Objective To understand the value of dynamic magnetic resonance enhancement and fat suppression in the diagnosis of pancreatic cancer. Materials and Methods 18 patients with pancreatic cancer confirmed by pathology underwent MRI. The magnetic resonance sequences used were SET1WI, FSET2WI, fat suppression SET1WI, and dynamic enhanced FMPSPGR. Results In 18 cases of pancreatic cancer tumors, 10 patients showed low signal on SET1WI, 6 patients had equal signal, 2 patients had high signal, 8 patients had high signal on FSET2WI, 6 patients had signal, 4 patients had low signal. Fat suppression technique showed low signal changes in all tumors on SET1WI. At the same time, in the dynamic enhancement of FMPSPGR arterial phase scan, all tumors showed no significant or no enhancement and showed low signal. Conclusion The fat suppression technique SET1WI and dynamic enhanced FMPSPGR can significantly improve the sensitivity and specificity of pancreatic cancer diagnosis.
