颌面部软组织富血供肿瘤MDCT增强联合CTA多维技术应用价值

Application Value of MDCT Enhancement Combined with CTA Multidimensional Technology in Maxillofacial Soft Tissue Hypervascular Tumors

目的:应用MDCT增强联合CTA多维技术评价口腔颌面部软组织富血供肿瘤临床影像特征。方法:回顾性分析21例富血供肿瘤影像血供程度及指标,以病理结果作为诊断金标准,评价MDCT平扫及增强联合CTA多维技术对口腔颌面部软组织富血供肿瘤诊断的灵敏度与特异度,并绘制ROC曲线,分析评估效能。结果:21例患者中,MDCT增强联合CTA多维技术诊断准确率为90.48%,静脉期CT值的AUC为0.80,灵敏度为83.30%,特异度为72.73%。结论:MDCT增强联合CTA多维技术可用于术前评估颌面部软组织富血供肿瘤血供程度,其中肿瘤静脉期CT值评价效能最高,为规避颌面部富血供肿瘤术中失血的风险,术前无创性评估肿瘤血供的方法对临床治疗方案制定具有一定指导意义。

Objective:To evaluate the clinical imaging features of oral and maxillofacial hypervascular tumors in oral and maxillofacial soft tissue by MDCT enhancement combined with CTA multi-dimensional technique.Methods:The degree of blood supply and indexes of 21 cases of hypervascular tumors were retrospectively analyzed,and the pathological results were used as the diagnostic gold standard to evaluate the sensitivity and specificity of MDCT plain scan and enhanced CTA multidimensional technology in the diagnosis of oral and maxillofacial soft tissue hypervascular tumors.The ROC curve was drawn to analyze and evaluate the efficacy.Results:Among 21 patients,the diagnostic accuracy of MDCT enhancement combined with CTA multidimensional technology was 90.48%,the AUC of venous phase CT value was 0.80,the sensitivity was 83.30%,and the specificity was 72.73%.Conclusion:MDCT enhancement combined with CTA multi-dimensional technology can be used to evaluate the blood supply of maxillofacial soft tissue hypervascular tumors before operation,and the CT value in the venous phase of tumors has the highest evaluation efficiency,which can reduce the risk of blood loss during maxillofacial hypervascular tumors.The preoperative non-invasive assessment of tumor blood supply has certain guiding significance for the formulation of clinical treatment plans.
