Figure Lengend Snippet: The Bland-Altman plots showed a good agreement between the calculated BMD assessment of 346 patients based on HAP-iodine (A) and Ca-iodine (B) derived from fast-switching DECT and reference BMD derived from QCT. The mean BMD differences are shown by the solid blue lines, and the 95% limits of agreement (mean ± 1.96 SD) are shown by the dotted red lines. The predicted BMD from HAP-iodine and Ca-iodine images and reference BMD were in good agreement. BMD, bone mineral density; HAP, hydroxyapatite; SD, standard deviation; Ca, calcium; DECT, dual-energy computed tomography; QCT, quantitative computed tomography.
Article Snippet: Additionally, the QCT BMD Model 4 Asynchronous CT Calibration Phantom (Mindways Software Inc., Austin, TX, USA) was scanned to ensure the accuracy of BMD measurement.
Techniques: Derivative Assay, Standard Deviation, Computed Tomography
