磁共振与多层螺旋CT在胰腺囊性病变诊断中的应用比较

Comparison of application between magnetic resonance imaging and multislice spiral CT in the diagnosis of pancreatic cystic lesions

目的探讨比较磁共振(MRI)与多层螺旋CT(MSCT)在胰腺囊性病变诊断中的应用效果。方法选取2018年11月~2019年11月我院收治的53例胰腺囊性病变患者作为研究对象。所有患者在术前均依次进行MRI、MSCT检查。以最终的手术病理检查作为诊断的金标准,比较MRI、MSCT检查在胰腺囊性病变诊断中的应用效果,并比较两种检查方法的检查用时。结果在53例患者中,经术后病理学结果确诊为假性囊肿14例,真性囊肿5例,黏液性囊性肿瘤9例,浆液性囊性肿瘤7例,实性假乳头肿瘤6例,导管内乳头状黏液瘤8例,囊腺癌4例。以术后病理学结果为金标准,MRI、MSCT检查诊断胰腺囊性病变的符合率分别为98.11%、92.45%,两者比较差异无统计学意义(P>0.05)。MSCT的检查用时为(19.6±3.2)min,短于MRI的(28.7±4.1)min,差异有统计学意义(t=5.351,P<0.05)。结论在胰腺囊性病变诊断中,MRI、MSCT两种检查方式均能得到较为准确的诊断效果,MSCT用时相对较短,检查更快速,而MRI检查能从多方位进行全面扫描,提供更多的囊变相关信息,临床应用时可根据实际情况选择适合的检查方式。

Objective To investigate and compare the application effect of magnetic resonance imaging(MRI)and multilayer spiral CT(MSCT)in the diagnosis of pancreatic cystic lesions.Methods From November 2018 to November 2019,a total of 53 patients with pancreatic cystic lesions admitted to our hospital were selected as the research subjects.All patients were examined with MRI,MSCT sequentially before operation.Final surgical pathology examination was used as the gold standard for diagnosis,and the application effect of MRI,MSCT examination in the diagnosis of pancreatic cystic lesions was compared,and the examination time of the two methods was compared.Results Among the 53 patients,14 cases were pseudocyst,5 cases were true cyst,9 cases were mucinous cystic tumor,7 cases were serous cystic tumor,6 cases were solid pseudopapillary tumor,8 cases were intraductal papillary myxoma and 4 cases were cystadenocarcinoma according to pseudocyst by postoperative pathology.With the postoperative pathological results as the gold standard,the coincidence rate of MRI,MSCT examination and diagnosis of pancreatic cystic lesions was 98.11%and 92.45%,and there was no significant difference between the two methods(P>0.05).The examination time of MSCT was(19.6±3.2)min,which was shorter than(28.7±4.1)min of MRI,the difference was statistically significant(t=5.351,P<0.05).Conclusion In the diagnosis of pancreatic cystic lesions,MRI and MSCT examination methods can get relatively accurate diagnosis effect,the time of MSCT is relatively short,the examination is faster,while the MRI examination can carry on the comprehensive scan from the multi-directional,provides the more sac changes related information,the clinical application may choose the suitable examination way according to the actual situation.
