| 摘 要： | 目的比较上腹部常规磁共振成像(MRI)结合磁共振胰胆管成像(MRCP)与薄层T2WI-STIR序列结合MRCP对胆总管泥沙样结石的诊断准确性。方法 58例经临床手术或内镜逆行胰胆管造影(ERCP)证实的胆总管泥沙样结石患者均经上腹部常规MRI、MRCP及薄层T2WI-STIR序列扫描。随后,对常规MRI+MRCP与薄层T2WI-STIR序列+MRCP探测胆总管泥沙样结石的检出率进行比较。结果与手术或ERCP所见相对照,常规MRI+MRCP在58例胆总管泥沙样结石患者中检出33例,符合率为56.9%;而薄层T2WI-STIR序列+MRCP检出胆总管泥沙样结石44例,符合率为75.9%。两种方法对胆总管泥沙样结石的检出率有显著性差异(P<0.05)。结论与常规MRI+MRCP比较,薄层T2WI-STIR序列+MRCP对胆总管泥沙样结石有更高的诊断准确性。

| Abstract: | Objective To compare the diagnostic accuracy of conventional magnetic resonance imaging(MRI) of the upper abdomen plus magnetic resonance cholangiopancreatography(MRCP) versus thin-slice T2WI-STIR sequence plus MRCP for detecting choledochal silty stones(CSS).Methods Fifty-eight patients with surgically or endoscopic retrograde cholangiopancreatography(ERCP) proved CSS underwent conventional MRI of the upper abdomen,MRCP and thin-slice T2WI-STIR sequence scans.Subsequently,the detecting rate of thin-slice T... |
