We assess the utility of transparent 3D reconstructed CT images for evaluation of traumatic pelvic bony injuries compared to traditional radiographs.
Radiographs and 3D reconstructed CT were anonymized and randomized before review by 4 board certified physicians using a standardized questionnaire and compared to a gold-standard axial CT by a fifth board certified physician.
49 patients were included. We found significant agreement (K=[0.5-0.92], p<0.001) and comparable accuracy (K=[0.36-0.38], p<0.02) and ghost images of radiographs and transparent 3D reconstructed CT without a difference in confidence (p=0.38).
Transparent 3D reconstructed CT images may be sufficient for pelvic trauma injury without the use of radiographs.
与传统X线片相比，我们评估透明三维重建CT图像在评估创伤性骨盆骨损伤中的效用。
在4名获得委员会认证的医师使用标准化问卷进行评估之前，对X线片和三维重建CT进行匿名化和随机化处理，并由第5名获得委员会认证的医师与金标准轴向CT进行比较。
纳入49例患者。我们发现X线片和透明三维重建CT之间存在显著一致性（K = [0.5 - 0.92]，p < 0.001）、可比的准确性（K = [0.36 - 0.38]，p < 0.02）以及X线片和透明三维重建CT的伪影图像，且信心无差异（p = 0.38）。
不使用X线片时，透明三维重建CT图像可能足以用于骨盆创伤损伤评估。
