MRI与CT检查对急性胰腺炎的比较研究

Comparison of MRI and CT in Diagnosing Acute Pancreatitis

目的:分析急性胰腺炎(以下简称AP)病变在MRI各脉冲序列及CT的表现,比较各放射检查手段的不同。方法:AP住院患者40例,采用核磁检查的4种脉冲序列成像及CT成像。观察胰腺大小、形态、密度、信号改变,胰周有无渗出及范围,肾前筋膜有无增厚,有无急性液体积聚及假性囊肿。结果:MRCP原始像和3DMIP可准确评定渗出范围,与周围器官的关系;CT对组织的水肿、出血较为敏感,可判断病变组织是单纯的水肿,还是合并积液。结论:在本项研究实验中,MRI与CT对AP诊断结果相差不大,在指导临床治疗方面,MRI的作用优于CT。

Objective Analysis of acute pancreatitis(AP) lesions in every pulse sequence in MRI and CT, comparing the different of radiological examination means.Methods The 4 kinds of pulse sequence imaging and CT imaging were used in AP hospital. To observe the size, morphology, density, signal change of pancreas, whether the pancreas was seepage and range,the anterior fascia of the kidney was thickened, and there was no acute liquid accumulation and pseudocyst.Results The original image of MRCP and 3 DMIP can accurately assess the exudate range and the relationship with the surrounding organs.CT is more sensitive to tissue edema and hemorrhage, which can be determined whether the lesion tissue is simple edema or combined effusion.Conclusion In this study, MRI and CT have no difference in the diagnosis of AP, and MRI is better than CT in guiding clinical treatment.
