常规MRI序列、MRCP序列及DWI序列在术前诊断良恶性壶腹周围病变中的应用

目的常规磁共振成像(MRI)序列、MRCP序列及DWI序列在术前诊断良恶性壶腹周围病变中的应用。方法选择2014年7月到2018年7月到医院就诊壶腹周围病变患者80例,所有患者均进行MRI常规序列、MRCP序列及DWI序列检查。统计良恶性壶腹周围病变在MRI常规序列、MRCP序列及DWI序列的图像特点,统计MRI常规序列、MRCP序列、DWI序列及三者联合对不同良恶性壶腹周围病变检出率,统计MRI常规序列、MRCP序列、DWI序列及三者联合对诊断良恶性壶腹周围病变诊断效能。结果良性病变及恶性病变在MRI常规序列、MRCP序列及DWI序列图像上均有明显差异(P<0.05);联合检测对壶腹周围炎性病变检出率高于单一检测(P<0.05);联合检测对良恶性壶腹周围病变检测准确性高于单一检测(P<0.05)。结论常规MRI序列、MRCP序列及DWI序列在判断良恶性壶腹周围病变上均有较好诊断效能,三者联合诊断准确性更高。

Application of Conventional MRI Sequence,MRCP Sequence and DWI Sequence in Preoperative Diagnosis of Benign and Malignant Periampullary Lesions

Objective To investigate the application of conventional magnetic resonance imaging(MRI) sequence, MRCP sequence and DWI sequence in the preoperative diagnosis of benign and malignant periampullary lesions. Methods 80 cases of patients with periampullary lesions from July 2014 to July 2018 in the hospital were selected. All patients were given conventional MRI sequence, MRCP sequence and DWI sequence. The imaging features of conventional MRI sequence, MRCP sequence and DWI sequence in the diagnosis of benign and malignant periampullary lesions were counted, and the detection rates of different benign and malignant periampullary lesions were counted by conventional MRI sequence, MRCP sequence, DWI sequence and the three combined detection. The diagnostic efficacy of conventional MRI sequence, MRCP sequence, DWI sequence and the three combined detection was counted in the diagnosis of benign and malignant periampullary lesions. Results There were significant differences in the images of benign lesions and malignant lesions in conventional MRI sequence, MRCP sequence and DWI sequence(P<0.05). The detection rate of periampullary lesions by combined detection was higher than that by single detection(P<0.05). The detection accuracy of combined detection for benign and malignant periampullary lesions was higher than that of single detection(P<0.05). Conclusion Conventional MRI sequence, MRCP sequence and DWI sequence have good diagnostic efficacy in judging the benign and malignant periampullary lesions. The three combined diagnosis has high accuracy.
