Accuracy errors in longitudinal QCT measurements of cortical thickness bone mineral density and bone mineral content using different segmentation techniques: a simulation study

Introduction: The quantification of cortical BMD and thickness in QCT images remains challenging due to the limited spatial resolution of CT scanners. We simulated the impact of longitudinal cortical BMD and thickness changes on accuracy of cortical measurements using three different segmentation algorithms.Methods: A step function of varying width d (cortical thickness) and height (cortical BMD) and an additional step representing trabecular BMD was con...
