Figure Lengend Snippet: A flowchart of patient enrollment. CT, computed tomography; BMD, bone mineral density.

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: Computed Tomography

The linear regression equations of HAP-iodine and Ca-iodine. Significant positive correlations were found between the HAP-iodine density, Ca-iodine density, and BMD. (A) HAP-iodine had a linear relationship with the standard BMD (r=0.9472, R 2 =0.8973). (B) Ca-iodine had a linear relationship with the standard BMD (r=0.9470, R 2 =0.8968). BMD, bone mineral density; HAP, hydroxyapatite; Ca, calcium.

Techniques:

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.
