MRCP征象分析对胆道梗阻良恶性的诊断价值
|
摘要
目的分析MRCP中常见征象的影像学特征,比较其对良恶性胆道梗阻疾病的诊断价值。方法回顾性分析124例临床怀疑有胆道梗阻疾病患者的MRCP影像及全部临床资料,检查结果最终由手术病理或随访证实。详细分析全部研究对象MRCP常见征象的影像学特点。结果 "软藤征"、"空虚征"、"双管征"、"截断征"等在恶性梗阻中的显示率显著高于良性梗阻(P<0.05);"枯树征"、"杯口征"、"充盈缺损"等征象在良性梗阻中的显示率显著高于恶性梗阻(P<0.05)。结论 MRCP对良恶性胆道梗阻显示率高,具有一定的特异性征象。
objective To analyze the imaging features of common signs in MRCP, and to compare the diagnostic value of benign and malignant biliary obstructive diseases. Methods The MRCP images and all clinical data of 124 patients with suspected biliary obstruction were analyzed retrospectively. The final results were confirmed by surgical pathology or follow-up. The imaging features of the common signs of MRCP images were analyzed in detail. Results The "vine sign", "empty sign", "double duct sign", "cut off sign" in malignant obstruction of the display rate was significantly higher than those in benign obstruction(P<0.05); and the "dead branches syndrome", "cup mouth syndrome", "filling defect" in benign obstruction of the display rate were significantly higher than those in malignant obstruction(P<0.05). Conclusion MRCP has a high rate of benign and malignant biliary obstruction, and the diagnosis of benign and malignant biliary obstruction is of some special features.
