摘要目的探讨与MR比较,双能CT(DECT)虚拟去钙成像是否能提高不同经验影像医师对骨质疏松病人急性胸腰椎压缩性骨折的检出率。材料与方法这项回顾性研究经本单位伦理委员会批准,所有病人签署知情同意书。49例疑为急性脊椎骨折的骨质疏松症病人行DECT和MR检查,得到传统线性混合能量CT和相应的虚拟去钙重建图像。5位不同经验的影像医师观察灰阶CT影像确定有无骨折及期
Abstract Objective To investigate whether dual-energy CT (DECT) imaging can improve the detection rate of acute thoracolumbar vertebral compression fractures in patients with osteoporosis compared with MR imaging. Materials and Methods This retrospective study was approved by the Ethics Committee of this unit and all patients signed informed consent. 49 cases of suspected osteoporosis in patients with acute vertebral fracture DECT and MR examination, the traditional linear mixed energy CT and the corresponding virtual image of calcium to reconstruct. Five different experience of imaging physicians observed grayscale CT images to determine the presence or absence of fractures and period
