摘要
目的:研究基于能谱CT物质分离技术鉴别急性和慢性骨质疏松性椎体骨折的效果.方法:择取2020年6月至2023年6月之间收治的180例骨质疏松性椎体骨折患者作为研究对象,以"金标准"磁共振(MRI)结果为依据,将患者分为急性组(急性骨质疏松性椎体骨折组)和慢性组(慢性骨质疏松性椎体骨折组),每组各90例,根据Genant椎体骨折分级标准,椎体压缩骨折程度分为3级,分别是轻度、中度和重度,评估HAP-水、钙-水及骨密度值的诊断能力.结果:急性组的HAP-水、钙-水值高于慢性组,在不同椎体压缩骨折程度下,急性组的HAP-水、钙-水依然更高,且慢性组的骨密度值低于急性组,差异有统计学意义(P＜0.05).结论:急性和慢性骨质疏松性椎体骨折使用能谱CT物质分离技术能够有效鉴别,具有临床推广价值.
Abstract
Objective:To study the effect of energy spectrum CT material separation technique in differentiating acute and chronic osteoporotic vertebral fractures.Methods:A total of 180 patients with osteoporotic vertebral fractures were en-rolled between June 2020 and June 2023.The patients were divided into two groups:the acute group(acute osteoporotic ver-tebral fractures)and the chronic group(chronic osteoporotic vertebral fractures),with 90 patients in each group.Vertebral compression fractures were classified into three grades:mild,moderate,and severe.The diagnostic ability of HAP-water and calcium-water was evaluated.Results:The values of HAP-water and calcium-water in the acute group were higher than those in the chronic group.Additionally,HAP-water and calcium-water values in the acute group were consistently higher across different grades of vertebral compression fractures(p<0.05).Conclusion:The energy spectrum CT material separa-tion technique can effectively differentiate acute and chronic osteoporotic vertebral fractures and has clinical value.
