目的前瞻性比较仰卧非负重位（NWBCT）和直立负重位（WBCT.Methods）后足CT检查结果。对22名患者（平均年龄46.0 ± 17.1岁;范围19-75岁）进行了踝关节的NWBCT和WBCT扫描，NWBCT使用传统的64排CT，WBCT使用新型锥形束CT。两名肌肉骨骼放射科医生独立进行了以下测量：后足对线角，腓骨跟和胫跟距离，外侧距跟关节间隙宽度，距跟重叠和舟跟距离。使用Wilcoxon符号秩检验寻找NWBCT和WBCT之间的显著变化。P值
Objectives To prospectively compare computed tomography (CT) of the hindfoot in the supine non-weight-bearing position (NWBCT) with upright weight-bearing position (WBCT).Methods Institutional review board approval and informed consent of all patients were obtained. NWBCT and WBCT scans of the ankle were obtained in 22 patients (mean age, 46.0+/-17.1 years; range 19-75 years) using a conventional 64-row CT for NWBCT and a novel cone-beam CT for WBCT. Two musculoskeletal radiologists independently performed the following measurements: the hindfoot alignment angle, fibulocalcaneal and tibiocalcaneal distances, lateral talocalcaneal joint space width, talocalcaneal overlap and naviculocalcaneal distance. Significant changes between NWBCT and WBCT were sought using Wilcoxon signed-rank test. P values
