目的通过与手术所见对比,评价多排螺旋CT血管成像(multi-slice spiral computerized tomography angiograph,MDCTA)判定骨骼肌肉肿瘤毗邻血管受侵的临床价值。方法回顾性分析2008年1月至2014年6月,我院经MRI诊断为骨骼肌肉肿瘤并侵犯其毗邻血管的患者21例,所有患者均行手术治疗,并在术前进行MDCTA检查。其中男12例,女9例;平均年龄33岁;肢体骨肿瘤11例,肢体软组织肿瘤10例。采用双盲法通过MDCTA判断是否存在肿瘤毗邻血管受侵。以手术所见为金标准,进行统计学分析对比。结果 12例MDCTA未显示血管受侵者,手术所见也为阴性(真阴性12例);9例MDCTA显示血管受侵者中,3例虽术中发现血管与肿瘤粘连,但易于分离,被认为术中所见为阴性(假阳性3例),其余6例手术证实血管受侵(真阳性6例)。对比手术所见,MDCTA的敏感性为100%,特异性为80%,阳性预测值为66.7%,阴性预测值为100%,准确率为85.7%。结论 MDCTA评价骨骼肌肉肿瘤对毗邻血管侵犯更为准确,可提供真实可靠的影像学信息。 Objective To evaluate the clinical value of multislice spiral computerized tomography angiograph (MDCTA) in determining the adjacent vascular invasion of skeletal muscle tumors. Methods From January 2008 to June 2014, 21 patients with MRI diagnosed as skeletal muscle tumors and infiltrating adjacent blood vessels in our hospital were retrospectively analyzed. All patients underwent surgical treatment and were examined by MDCTA before operation. Including 12 males and 9 females; mean age 33 years; limb bone tumors in 11 cases, 10 cases of limb soft tissue tumors. Double-blind method by MDCTA to determine whether there is tumor adjacent to vascular invasion. Surgical findings as the gold standard for statistical analysis and comparison. Results 12 patients with MDCTA showed no vascular invasion, and the findings were negative (12 patients were negative). Among 9 patients with MDCTA, 9 showed vascular invasion and tumor adhesion in operation, but they were easy to separate That intraoperative findings were negative (false positive in 3 cases), and the remaining 6 cases of vascular invasion confirmed surgery (true positive in 6 cases). Compared with the surgical findings, MDCTA had 100% sensitivity, 80% specificity, 66.7% positive predictive value, 100% negative predictive value, and 85.7% accuracy. Conclusion MDCTA evaluation of skeletal muscle tumors on the adjacent vascular invasion more accurately, to provide true and reliable imaging information.
