全脊柱数字化拼接成像技术的临床应用价值

目的探讨拼接法数字化全脊柱成像在脊柱侧弯、旋转畸形的诊断、治疗及治疗后复查的临床应用价值。方法在DR数字化成像设备及PACS影像处理系统上，检查134例脊柱侧弯、旋转病例，共获得168帧全脊柱影像，进行图像质量评估和图像观察、测量。结果拼接后的图像与拼接前的图像甲片率差异无统计学意义（自由度=2，x2=1．48，P〉0．05）。全脊柱图像质量能满足临床对全脊柱进行观察、诊断及对Cobb角、临床人体平衡线的测量要求。结论拼接法全脊柱成像清晰显示全段脊柱结构，满足临床脊柱侧弯、旋转畸形测量要求，具有较大临床应用价值。

Application of the Digital Radiography Joint for the Total Spinal Column

Objective To investigate the digital radiography （ DR ） having been jointed for the total spinal column in the diagnosis, treating and rechecking for scoliolosis and spinal rotation. Methods All 134 patients who had scoliolosis or spinal rotation were examined with DR equipment and all original imaging were prosessed on PACS, 168 jointed total spinal column imaging had been analysed, including imaging quality, spinal observation and measurement. Results The difference of grade A between original and jointed spine imaging showed no statistical siginificance （ P ~ 0.05 ）. The jointed total spinal imaging were satisfied in observing total spinal structure and measuring Cobb angle and demic balancing line. Conclusion The jointed total spinal column imaging provided significant value in diagnosing and measuring for scoliolosis and spinal rotation , due to its ability to display spinal structure clearly.
