DR全脊柱摄影技术在脊柱侧弯中的应用与优势

目的:探讨数字化X线摄影(DR)全脊柱摄像技术在脊柱侧弯中的应用和优势。方法:收集2012年2月至2013年6月于本院进行治疗的脊柱侧弯病例88例,应用数字化X线摄影(DR)技术对脊柱由上至下进行正位和侧位的扫描,均进行3次曝光,每两次曝光间隔均为9秒,曝光后通过图像拼接技术将患者脊柱图像进行拼接和重叠,形成全景图像,对全部患者的图像质量进行观察和评估。结果:所有入选病例中有84例患者图像清晰显示了脊柱侧弯的方向和角度、椎体和椎间隙、对称的椎弓根、根间距及对脏器的影响程度。其中1例因运动不合作出现伪影,3例曝光不足。全脊柱图像质量正位优秀率为92.43%,侧位优秀率为85.92%;全脊柱图像拼接正位优秀率为83.44%,侧位优秀率为86.58%。结论:数字化X线摄影(DR)技术应用上方便快捷,患者配合时间较短,图像质量较好,能够满足临床医生进行诊断和治疗,有助于患者预后康复情况的评估,值得在临床诊断中推广应用。

Application and Advantages of DR Full Spine Imaging Technique in Scoliosis

Objective:To explore the applications and advantages of digital radiography (DR) full spine imaging technique in scoliosis.Methods:88 cases of scoliosis patients were treated between February 2012 and June 2013 in our hospital, and supplicated digital radiography (DR) of frontal and lateral scanning for the spine from top to bottom, 3 exposures, each two exposure interval of 9 seconds. After exposure, the spinal image were stitched and overlapped by image stitching technology, and formed a panoramic image. The image quality of all patients were observed and evaluated.Results:Of all patients, 84 patients'' images clearly showed scoliosis direction and angle, vertebral body and intervertebral space, symmetric vertebral pedicle, root spacing and the influence degree on organ. Amongthem, one case occurred artifacts due to motion cooperation, and there were 3 cases with insufficient exposure. Total spine image quality excellent rate was 92.43 %, the side excellent rate was 85.92 %; the whole spine image mosaic excellent rate was 83.44 %, the side excellent rate of 86.58%.Conclusion:Digital radiography(DR) technology is convenient, with advantages of short coordination time and better image quality. It can meet the needs of clinicians for diagnosis and treatment, and be helpful to valuate, recovery situations, so it is worthy to be popularized in clinical diagnosis.
