Methods The MSCT and digital radiography (DR) data of 39 cases with atlantoaxial injury verified by clinical workups were retrospectively analyzed. Results Total 50 pieces of bone fractures was found in all of 39 cases, in which a combination of dislocation was found in 9 cases and 广州医学院附属广州市第一人民医 a simple atlas-axis j oint half-dislocation were seen in 10 cases. DR could accurately 院放射科 陈汉忠 徐宏刚 determine the final diagnostic rates as high as 68%(34/50) in 50 pieces of bone fracture and 47.3% （9/ 19 ）in 19 cases of dislocation , and the rates of CT scan were 90%(45/ 50) and 68.4% （13/ 19 ）,respectively;and surface shaded display(SSD) were 96% （48/ 50 ）and 100% （19/ 19 ）,respectively;and multiplanar reconstruction(MPR) were 100% 【摘要】 目的探讨多层螺旋CT扫描 及三维重建技术在寰枢椎损伤中的 （50/50 ）and 100% （19/ 19 ）,respectively .
