Quantitative computed tomography
vBMD
To support the improved change in hip structure with ABL, patients in each treatment group were monitored using 3D QCT to assess changes in total vBMD, cortical vBMD, and trabecular vBMD in the total hip and FN. Patients enrolled at sites equipped with 3D QCT analysis systems were eligible for the analysis. Scans were acquired using one of two CT machines, namely, Aquilion (Canon Medical Systems Corp., Tochigi, Japan; slice thickness: 0.5 mm) and MX 16 (Philips and Neusoft Medical Systems Co., Shenyang, China; slice thickness, 1.0 mm). All scans were performed at a tube voltage of 120–140 kVp and tube current of 250 mA (Online Resource
