Clinical value of multi-slice spiral CT angiography in the diagnosis of abdominal tumors

Abstract

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(χ2=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(χ2=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.
