【摘要】 目的探讨64排结肠造影(CTC)在结肠病变检测中的应用。方法 80例怀疑结肠疾病的患者进行了CTC,采用多种后处理技术来显示结肠病变和邻近器官受累。结果 80例患者中,结直肠癌60例(其中肿块94个),结肠多发息肉、腺瘤20例(其中2例为家族性多发息肉合并恶变患者),检出肿瘤样病变共124个。钡灌肠、结肠镜检查和64排结肠造影在病变检出方面对比差异无统计学意义(P>0.05)。64排结肠造影敏感度为95.16%,特异度为88.46%,阳性预测值为97.52%,阴性预测值为79.31%。钡灌肠、结肠镜检查敏感度为86.29%,特异度为65.3%,阳性预测值为92.24%,阴性预测值为50.00%。结论 64排结肠造影在提高和定位结肠病变,诊断准确性方面都有着良好的效果。更多还原

【Abstract】 Objective To investigate the 320 row of dynamic volume CT colonography( CTC) in colon lesion detection application. Methods 80 cases of suspected colonic disease underwent CTC, using a variety of processing technology to display the colonic lesion and involvement of adjacent organs. Results 60 were colorectal cancer(94 masses), 20 were colorectal polyps and adenomas(2 were familial polyps with malignant transformation), and 124 tumor like lesions were detected. There was no significant difference between barium enema, colonoscopy and 64 row dynamic volume CT colonography in the detection of lesions. The sensitivity, specificity, positive predictive value and negative predictive value of SIEMENS 64 row colonography were 95.16%, 88.46%, 97.52% and 79.31%, respectively. The sensitivity, specificity, positive predictive value and negative predictive value of barium enema and colonoscopy were 86.29%, 65.3%, 92.24% and 50.00%, respectively. Conclusion 64 row dynamic volume CT colonography has a good effect in improving and locating colonic lesions and diagnostic accuracy.更多还原
