目的：通过与手术所见对比，评价多排螺旋CT血管成像(multi-slicespiralcomputerized tomographyangiograph，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。
目的：通過與手術所見對比，評價多排螺鏇CT血管成像(multi-slicespiralcomputerized tomographyangiograph，MDCTA)判定骨骼肌肉腫瘤毗鄰血管受侵的臨床價值。方法迴顧性分析2008年1月至2014年6月，我院經MRI診斷為骨骼肌肉腫瘤併侵犯其毗鄰血管的患者21例，所有患者均行手術治療，併在術前進行MDCTA檢查。其中男12例，女9例；平均年齡33歲；肢體骨腫瘤11例，肢體軟組織腫瘤10例。採用雙盲法通過MDCTA判斷是否存在腫瘤毗鄰血管受侵。以手術所見為金標準，進行統計學分析對比。結果12例MDCTA未顯示血管受侵者，手術所見也為陰性(真陰性12例)；9例MDCTA顯示血管受侵者中，3例雖術中髮現血管與腫瘤粘連，但易于分離，被認為術中所見為陰性(假暘性3例)，其餘6例手術證實血管受侵(真暘性6例)。對比手術所見，MDCTA 的敏感性為100%，特異性為80%，暘性預測值為66.7%，陰性預測值為100%，準確率為85.7%。結論 MDCTA評價骨骼肌肉腫瘤對毗鄰血管侵犯更為準確，可提供真實可靠的影像學信息。

Objective To evaluate the effectiveness of multi-slice spiral computerized tomography angiograph ( MDCTA ) in determining vascular invasion in patients with musculoskeletal tumors, and to compare the results with the surgical ifndings.Methods From January 2008 to June 2014, 21 patients diagnosed musculoskeletal tumors with vascular invasion based on magnetic resonance imaging ( MRI ) underwent MDCTA examination before surgical treatment. Their clinical data were retrospecitvely analyzed, including 11 cases of limb bone tumors and 10 cases of limb soft tissue tumors. There were 12 males and 9 females, whose mean age was 33 years old. The double-blind method was used to determine the presence of vascular invasion based on MDCTA examination results. The statistical analysis was carried out by using surgical ifndings as the gold standard.Results Twelve patients without vascular invasion according to the MDCTA examination were also surgically negative ( true negative ). Among the 9 patients with vascular invasion shown by the MDCTA examination, only 3 patients had adhesions and were considered surgically negative ( false positive ). The other 6 patients had vascular invasion proven by surgery and were considered surgically positive ( true positive ). Based on the surgical ifndings, the sensitivity of MDCTA was 100%, speciifcity 80%, positive predictive value 66.7%, negative predictive value 100%, and accuracy 85.7%.Conclusions MDCTA is an accurate imaging technique in evaluating vascular invasion of musculoskeletal tumors, which can provide valuable and authentic imaging information.
