Paper Abstract

Single kVp and dual energy CT imaging were utilized for the assessment of bone mineral content. In this approach, the CT values obtained from the trabecular portion of the lumbar vertebrae were related to known mineral concentrations in compartments of a calibration phantom that is scanned simultaneously with the patients. Both pre-reconstruction and post reconstruction dual energy CT methods were utilized in this study. The results obtained from single kVp scans were compared with the data from dual kVp scans. The influence of marrow fat content, variations in the calibration phantom, beam hardening effects and scanner drifts upon the accuracy and precision of the bone mineral measurements were investigated.
