CT血管成像对腹部肿瘤血供来源的诊断价值

Diagnostic value of blood supply sources of abdominal tumor by CT vascular imaging

目的探讨CT血管成像对腹部肿瘤血供来源的诊断价值。方法选取2018年5月至2020年10月本院收治的经CT血管成像确诊为腹部肿瘤75例患者作为研究对象。观察肿瘤来源、组织学分类情况、肿瘤的供血动脉及肿瘤血管显示情况;比较术前CT血管成像结果与手术病理结果。结果腹部肿瘤来源部位主要为腹腔膜(5.33%)、胃肠道(20.00%)、卵巢(25.33%)、子宫(36.00%)、腹膜后(10.67%)、泌尿系统(2.67%)。通过虚拟现实(VR)或最大密度投影(MIP)重建的方法,75例患者中,56例患者显示肿瘤的供血动脉,占比74.67%。术前CT血管成像结果与手术病理结果比较差异无统计学意义。结论CT血管成像对腹部肿瘤血供来源的诊断价值较高,且诊断结果和手术病理诊断结果一致,临床可通过该方法辅助医生选择治疗方案,改善患者预后,应用价值较高。

Objective To explore the diagnostic value of CT vascular imaging for blood supply sources of abdominal tumors.Methods 75 patients with abdominal tumors diagnosed by CT vascular imaging who were admitted to our hospital from May 2018 to October 2020 were selected as the research subjects.The origin of the tumor,histological classification,the feeding arteries of the tumor and the display of tumor blood vessels were observed;the results of preoperative CT angiography and the results of surgical pathology were compared.Results The origin of abdominal tumors were mainly peritoneal membrane(5.33%),gastrointestinal tract(20.00%),ovary(25.33%),uterus(36.00%),retroperitoneum(10.67%),and urinary system(2.67%).Through virtual reality(VR)or maximum-intensity projection(MIP)reconstruction,56 of the 75 patients showed the arteries supplying the tumor,accounting for 74.67%.There was no significant difference between preoperative CT vascular imaging results and surgical pathology results.Conclusion CT vascular imaging is valuable in the diagnosis of blood supply of abdominal tumors,and the diagnosis is consistent with the pathology,this method can be used to assist doctors to choose treatment options,improving the prognosis,and the application value is high.
