目的探讨多层螺旋CT在结肠直肠肿瘤诊断中的临床应用价值。方法资料选取2011年3月至2013年3月我院收治的行结肠直肠肿瘤手术的患者150例,采用多层螺旋CT对其进行扫描诊断,观察总结其临床应用价值。结果 148例患者的平扫图像均表现为:肠壁不规则增厚,肠腔狭窄,且肠壁的局部有软组织包块,近端的肠管出现不同程度的扩张现象;增强扫描的图像显示,患者病灶区不均质强化;而容积再现重组的图像则清晰地显示,患者肠道的充盈和缺损;采用仿真内镜处理,其图像能较为清楚地显示患者肠腔内的肿瘤及其表面的情况。经病理检查后确诊为结直肠癌,其CT检查诊断准确率为98.7%。结论采用多层螺旋CT检查结肠直肠肿瘤具有较高的诊断准确率,其临床应用和推广价值较高。
Objective To investigate the clinical value of multi-slice spiral CT in the diagnosis of colorectal tumors. Methods Data 150 cases of colorectal cancer surgery admitted from March 2011 to March 2013 in our hospital were scanned by multi-slice spiral CT, and its clinical value was observed and summarized. Results The plain images of 148 patients showed irregular thickening of the intestinal wall and narrowing of the intestine, soft tissue mass in the intestinal wall, and varying degrees of dilatation in the proximal intestine. In the enhanced scan, Inhomogeneous enhancement of the lesion area of the patient; volume reconstruction and reconstruction of the image clearly shows the patient’s intestinal filling and defect; the use of simulated endoscopy, the image can be more clearly displayed in patients with intestinal tumor and its surface Happening. After pathological examination diagnosed with colorectal cancer, the diagnostic accuracy of CT examination was 98.7%. Conclusion The multi-slice spiral CT examination of colorectal tumors has a high diagnostic accuracy, and its clinical application and promotion of higher value.
