目的 探讨双能CT羟基磷灰石(HAP)-水分离技术鉴别急慢性椎体压缩骨折的价值.方法 回顾性分析31例胸椎/腰椎椎体压缩骨折患者的临床资料,以MRI诊断结果为参考标准,对双能CT虚拟去HAP(VNHAP)融合伪彩图进行视觉评估,并测量VNHAP灰度图中椎体相对水含量,计算医师视觉评估诊断急性椎体压缩骨折的敏感度、特异度及准确率;绘制ROC曲线,分析骨折椎体相对水含量对急性椎体压缩骨折的诊断效能.结果 31例中,MRI显示80个病变椎体,其中腰椎46个、胸椎34个,急性压缩骨折椎体45个、慢性压缩骨折椎体35个.医师视觉评估诊断急性椎体压缩骨折的敏感度为93.33％(42/45),特异度97.14％(34/35),准确率95.00％(76/80)...

Objective: To explore the value of dual-energy CT hydroxyapatite (HAP)-water decomposition technique in differential diagnosis of acute and chronic vertebral compression fractures (VCF). Methods: Data of 31 patients with thoracolumbar VCF were retrospectively analyzed. Taken MRI results as reference standards, the visual evaluation of fusing pseudo-color images of virtual nonhydroxyapatite (VNHAP) was conducted by physicians. The sensitivity, specificity and accuracy of visual assessment in diagnosis of acute VCF were calculated. Compare relati...
