目的探讨多层螺旋CT(MSCT)在梗阻性黄疸诊断中的临床应用价值,为临床诊断与治疗提供新的方法和依据。方法利用16层螺旋CT对43例肝内外胆管梗阻的患者进行检查,在工作站进行MPR、SCTC、VR、MIP技术处理,对胆管梗阻定位和定性诊断作出评价,并与手术病理对照。结果多层螺旋CT对梗阻性黄疸定位和定性准确率分别为100%和91%,术前评估结果与手术一致性极好。结论多层螺旋CT具有强大的后处理功能,对梗阻性黄疸定位和定性准确率高,在术前评估以及制定手术治疗方案等方面具有重要的参考价值。
Objective To investigate the clinical value of multi-slice spiral CT (MSCT) in the diagnosis of obstructive jaundice and to provide a new method and basis for clinical diagnosis and treatment. Methods 43 cases of intrahepatic and extrahepatic bile duct obstruction patients were examined by 16-slice spiral CT. MPR, SCTC, VR and MIP techniques were performed on the workstation to evaluate the location and qualitative diagnosis of bile duct obstruction and to compare with the surgical pathology. Results The accuracy and accuracy of multislice spiral CT in the diagnosis and classification of obstructive jaundice were 100% and 91%, respectively. The preoperative evaluation and operation consistency were excellent. Conclusion Multi-slice spiral CT possesses a powerful post-processing function, which has important reference value for the localization and qualitative accuracy of obstructive jaundice, preoperative evaluation and surgical treatment planning.
