摘　　要：目的研究动态增强CT与多层螺旋CT血管成像技术(MSCTA)联合用于盆腹部起源不明的巨大肿瘤的诊断价值。方法收集广东省人民医院南海医院2018年1月至2023年7月收治的96例盆腹部肿瘤患者临床资料,开展回顾性对比研究。以病理结果为金标准,分析动态增强CT与MSCTA在诊断盆腹部起源不明巨大肿瘤病变性质和病变类型中的临床价值。结果手术病理结果证实,恶性肿瘤病变66例,良性肿瘤病变30例。动态增强CT与MSCTA联合诊断盆腹部不明原因巨大肿瘤性质和病变类型的结果与手术病理结果一致性满意(Kappa值=0.832,0.911;P<0.001)。动态增强CT与MSCTA联合诊断病变性质的灵敏度为93.9%,特异度为90.0%,准确度为92.7%,阳性预测值为95.4%,阴性预测值为87.1%。手术病理结果证实,胃间质瘤23例,小肠间质瘤17例,子宫肌瘤12例,囊腺瘤22例,畸胎瘤14例,肝癌8例。MSCTA诊断病变类型的准确度为92.7%。结论动态增强CT与MSCTA联合用于盆腹部起源不明的巨大肿瘤性质和病变类型的诊断,具有较高准确性。Objective To study the diagnostic value of dynamic enhanced CT combined with multi-slice spiral CT angiography(MSCTA)for giant tumors of unknown origin in the pelvic and abdominal regions.Methods The clinical data of 96 patients with pelvic and abdominal tumors admitted to Nanhai Hospital of Guangdong provincial People′s Hospital from January 2018 to July 2023 were collected and conducted a retrospective comparative study.The clinical value of dynamic enhanced CT and MSCTA in diagnosing the nature and type of giant tumors of unknown origin in the pelvic and abdominal regions was analyzed by using pathological results as the gold standard.Results The surgical pathological results confirmed that there were 66 cases of malignant tumor lesions and 30 cases of benign tumor lesions.The results of dynamic enhanced CT combined with MSCTA in diagnosing the nature and type of unexplained huge tumors in the pelvic and abdominal regions were consistent with the surgical and pathological results(Kappa=0.832,0.911;P<0.001).The sensitivity,specificity,and accuracy of dynamic enhanced CT and MSCTA in diagnosing the nature of lesions were 93.9%,90.0%,and 92.7%,respectively,the positive predictive value was 95.4%,and the negative predictive value was 87.10%.The surgical pathological results confirmed that there were 23 cases of gastric stromal tumors,17 cases of small intestinal stromal tumors,12 cases of uterine fibroids,22 cases of cystadenomas,14 cases of teratomas,and 8 cases of liver cancer.The accuracy of MSCTA in diagnosing lesion types was 92.7%.Conclusion The dynamic enhanced CT combined with MSCTA has high accuracy in diagnosing the nature and type of giant tumors of unknown origin in the pelvic and abdominal regions.
