CT三维重建技术判断骨盆骨折Tile分型与二维CT及X线的对比研究
|
摘要
目的:对比分析64排螺旋CT三维重建技术判断骨盆骨折Tile分型的价值。方法:选取2017年1月至2018年6月接受治疗的51例骨盆骨折患者为对象,所有对象均先后给予X线、二维CT及CT三维重建检查,以手术诊断结果为金标准,对比三种检查方案的诊断效果。结果:金标准显示51例患者中Tile分型A型9例、B型30例、C型12例。CT三维重建对Tile分型的诊断准确率100.00%,明显高于X线扫描(74.51%)和二维CT(88.34%),差异有统计学意义(P<0.05)。X线扫描、二维CT均与金标准诊断结果有较高的一致性(к=0.696,0.859;P<0.001)。CT三维重建与金标准检测结果完全一致。结论:CT三维重建技术判断骨盆骨折Tile分型与手术诊断结果完全一致,优于二维CT与X线扫描。
Objective: To compare the value of 64 slice spiral CT three dimensional reconstruction in Tile classification of pelvic fractures. Methods: From January 2017 to June 2018, 51 patients with pelvic fractures were selected as subjects. All patients were examined by X-ray, two-dimensional CT and CT three-dimensional reconstruction. The diagnostic results of the three methods were compared according to the gold standard of surgical diagnosis. Results: According to the gold standard, there were 9 cases of Tile A type, 30 cases of B type and 12 cases of C type in 51 patients. The diagnostic accuracy of three-dimensional CT reconstruction for Tile classification was 100.00%, significantly higher than that of X-ray scanning(74.51%) and two-dimensional CT(88.34%), the difference was statistically significant(P<0.05). Both X-ray scan and two-dimensional CT were in good agreement with the gold standard(к = 0.696, 0.859, P<0.001). CT three-dimensional reconstruction is fully consistent with the gold standard test results. Conclusion: CT three-dimensional reconstruction is superior to two-dimensional CT and X-ray scan in judging Tile classification of pelvic fracture.
