64排螺旋CT和超声在阑尾炎诊断中的应用和效果对比

Clinical application of 64-slice spiral CT and ultrasonography in the diagnosis of appendicitis

目的:探讨64排螺旋CT在阑尾炎诊断中的应用效果。方法:采用回顾性分析的方式将急性阑尾炎疑似患者40例进行研究,其中经过临床病症资料与手术病理确诊有32例急性阑尾炎,其他8例为升结肠癌。先后对40例患者行B超诊断与64排螺旋CT诊断,对比分析两种诊断方式的特异度、灵敏度与准确度。结果:螺旋CT诊断急性阑尾炎的灵敏度、特异度以及准确度显著高于B超诊断,差异有统计学意义(P<0.05),经螺旋CT诊断有明显的直接与间接征象。结论:针对急性阑尾炎的诊断采用64排螺旋CT以及其曲面重建技术具有准确的判断能力,阑尾与周围情况也能清晰展示,诊断灵敏度、特异度与准确度都很高,值得在临床上推广应用。

Objective To explore the clinical application value of64-slice spiral CT and ultrasonography in the diagnosis of appendicitis.Method The clinical data about40patients suspected with acute appendicitis was reviewed.Through the clinical data and pathological examinations,there were32confirmed cases with acute appendicitis and8cases of colon cancer;bases on the B ultrasound and64-slice spiral CT,the diagnosis specificity,sensitivity and accuracy was compared.Results The diagnosis specificity,sensitivity and accuracy bases on the spiral CT examination was significantly higher than that of B ultrasound(P<0.05);the direct and indirect signs based on the spiral CT examination were clearly displayed.Conclusion For patients with acute appendicitis,the curve planar reconstruction technique based on the64-slice spiral CT has a better diagnosis effect,can clearly display the vermiform appendix and adjacent conditions as well as improve its clinical sensitivity,specificity and accuracy.It is worthy of clinical promotion and application.
