影像学检查在胆管梗阻病因诊断中的应用价值分析

目的分析并评价CT与磁共振检查方法在诊断胆管梗阻病因上的优缺点。方法对本院收治的91例胆管梗阻患者的病理检查、CT与胆管造影资料做回顾性分析。结果在胆管癌、胆管结石、炎性狭窄、肝癌以及壶腹癌的诊断方面，病理检查与MRI的符合程度高于病理和CT符合率，差异具有统计学意义；在胰头癌与肿大淋巴结的诊断方面，病理检查与MRI的符合程度与病理和CT符合率，差异无统计学意义；在诊断梗阻部位方面。手术与MRI的符合程度与手术与CT的符合程度无明显差异。结论磁共振作为一种无创性的影像检查方法，在胆管梗阻性疾病的诊断方面具有较高的准确性。

The applications value analysis of imaging examination for the diagnosis of biliary obstruction etiology

Objective To analyze and evaluate the advantages and disadvantages of the CT and MRI examination for the diagnosis of biliary obstruction.Methods The pathological,CT and biliary imaging material of 91 patients with biliary ob struction were retrospective analysised in our hospital.Results In the diagnosis of bile duct carcinoma,bile duct stones,inflammatory stenosis,liver cancer and ampullary cancer,the coincidence rate between pathological examination and MRI was higher than between pathology and CT,the comparing difference was statistically significant;In the diagnosis of pan creatic head carcinoma and lymph nodes pathological examination,the coincidence rate between pathological examination and MRI was not significantly different from that between pathology and CT;In the diagnosis of biliary obstruction,the co incidence rate between operation and MRI was not significantly different from that between operation and CT.Conclusion MRI is a noninvasive imaging method,and it has high accuracy in the bile duct obstructive disease diagnosis.
