目的 了解磁共振动态增强和脂肪抑制技术在胰腺诊断中的价值。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，采用在磁共振序列分别为：ＳＥＴ１ＷＩ、ＦＳＥＴ２ＷＩ、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；ＦＳＥＴ２ＷＩ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

The Value of MR Dynamic Contrast FMPSPGR and SE T1WI+Fat Suppress Techniques in the Diagnosis of Pancreatic Carcinoma

Objective To evaluate MR dynamic contrast FMPSPGR and T 1WI Fat suppress techniques in the diagnosis of pancreatic carcinoma.Materials and Methods MRI was performed in 18 cases with surgico-pathologically proved pancreatic carcinoma. SE T 1WI, FSE T 2WI, SE T 1WI Fat suppress and dynamic contrast FMPSPGR sequences were used in MR scanning.Results On SE T 1WI the lesions showed hypo- intensity in 10, iso-intensity in 6 and hyper-intensity in 2 cases, while on FSE T 2WI the lesions displayed hypo-intensity in 4, iso-intensity in 6 and hyper-intensity in 8 cases. In contrast, on SE T 1WI Fat suppress all the tumors appeared hypo-intensity. With dynamic contrast FMPSPGR sequence all lesions showed hypo-intensity without or with only slight enhancement during arterial phase scanning.Conclusion SE T 1WI Fat suppress and dynamic contrast FMPSPGR sequences can surely improve both the sensitivity and specificity of the diagnosis of pancreatic carcinoma.
