多层螺旋CT诊断急腹症的临床效果分析

Clinical Effect Analysis of Multislice Spiral CT in the Diagnosis of Acute Abdomen

目的:分析多层螺旋CT诊断急腹症的临床效果。方法:选取2019年10月—2022年7月郑州市第三人民医院收治的120例急腹症患者作为研究对象,入院后对其进行多层螺旋CT扫描诊断,详细观察平扫特征和动态增强扫描的特征。联合应用图像重建(MPR)、容积重建技术(VRT)、最大密度投影(MIP)和曲面重建(CPR)等多种技术对扫描中得到的图像进行二维重建和三维重建,以手术结果为金标准,分析多层螺旋CT诊断的效果。结果:经手术证实,有29例梗阻性病变,17例穿孔性病变,22例出血性疾病,49例炎症性疾病以及3例缺血性病病变。多层螺旋CT诊断确诊为急腹症116例,诊断准确率为96.67%。其中梗阻性病变和穿孔性病变诊断准确率均为100.00%,出血性疾病、炎症性疾病以及缺血性病病变的诊断准确率分别为95.45%、95.92%和66.67%。结论:临床上对急腹症患者实施诊断时应用多层螺旋CT诊断,准确率较高,能够为临床治疗提供可靠的指导依据。

Objective:To analyze the clinical effectiveness of multislice spiral CT in the diagnosis of acute abdomen.Methods:120 patients with acute abdomen admitted to the hospital from October 2019 to July 2022 were selected as the study subjects,who were diagnosed with multilayer spiral CT scans after admission to the hospital,and the features of plain scanning characteristics and dynamic enhancement scans were observed in detail.Multiple techniques such as Image reconstruction(MPR),Volume Rendering Technology(VRT),Maximum Density Projection(MIP)and Curved Planar Reformation(CPR)were jointly applied to perform 2D reconstruction and 3D reconstruction of the images obtained in the scans to analyze the effectiveness of multislice spiral CT diagnosis using surgical results as the gold standard.Results:There were 29 obstructive lesions,17 perforated lesions,22 hemorrhagic disorders,49 inflammatory disorders,and 3 ischemic disease lesions confirmed by surgery.The diagnosis of 116 cases of acute abdomen was confirmed by multislice CT diagnosis with a diagnostic accuracy of 96.67%.The diagnostic accuracy was 100.00%for both obstructive and perforating lesions,and 95.45%,95.92%,and 66.67%for hemorrhagic,inflammatory,and ischemic disease lesions,respectively.Conclusion:Clinical diagnosis of patients with acute abdomen using multislice spiral CT diagnosis,with high accuracy,can provide reliable guidance for clinical treatment basis.
