摘　　要：目的研究多层螺旋CT血管成像在腹部肿瘤临床诊断中的应用价值。方法选取研究对象为2015年1月至2017年12月在永康市第一人民医院进行治疗的腹部肿瘤患者,将90例患者根据双盲随机分组法分为两组,每组45例。将实施常规CT平扫的患者纳入对照组,将采用多层螺旋CT血管成像的患者设为观察组。将两组腹部肿瘤患者的扫描结果、腹部肿瘤侵袭范围及位置、血管显示情况和病灶灌注参数进行比对。结果观察组腹部肿瘤诊断准确率(93.33%)、腹部肿瘤侵袭范围及位置诊断准确率(80.00%)均高于对照组(χ^2=5.414、5.086,均P<0.05);恶性与交界性病灶管径正常者的1支供应动脉异常增粗(27例)、2支供血动脉增粗(8例)的比例均高于良性病灶管径正常者(χ^2=31.765、8.372,均P<0.05),且良性病灶管径正常者的对比剂平均通过时间[(10.55±3.02)s]、血流量[(21.54±5.58)mL·min^-1·100g^-1]、血容量[(4.04±0.76)mL/100g]、毛细血管表面通透性[(10.16±2.73)mL·min^-1·100g^-1],均少于恶性与交界性病灶管径正常者的1支供应动脉血管灌注参数(t=3.016、5.005、4.982、6.989,均P<0.05)。结论在腹部肿瘤临床诊断中,运用多层螺旋CT血管成像技术具有较高的准确率,可较好地显示血管异常状况。Objective To study the clinical value of multi-slice spiral CT angiography in the diagnosis of abdominal tumors. Methods From January 2015 to December 2017, 90 patients with abdominal neoplasms in the First People's Hospital of Yongkang were divided into two groups according to double-blind randomized method, with 45 patients in each group.The patients with conventional CT scan were included in the control group, and the patients with multislice spiral CT angiography were selected as the observation group.The scan results, invasion range and location of abdominal tumor, vascular display and perfusion parameters were compared between the two groups. Results The diagnostic accuracy of abdominal tumor and invasion range in the observation group(93.33%, 80.00%) was higher than those of the control group(χ^2=5.414, 5.086, all P<0.05). The proportions of abnormal thickening of one supply artery(27 cases) and two blood supply arteries(8 cases) in patients with malignant and borderline venereal lesions with normal diameter were higher than those of patients with benign lesions(χ^2=31.765, 8.372, all P<0.05). The contrast medium through time, blood flow, blood volume and capillary surface permeability in patients with benign lesions and normal average diameter were (10.55±3.02)s, (21.54±5.58)mL·min^-1·100 g^-1, (4.04±0.76) mL/100 g, (10.16±2.73)mL·min^-1·100 g^-1, respectively, which were lower than those of patients with malignant and border venereal focal lesions (t=3.016, 5.005, 4.982, 6.989, all P<0.05). Conclusion Application of multislice spiral CT angiography in the clinical diagnosis of abdominal tumors has high accuracy and can better display the abnormal condition of blood vessels.
