Abstract
Compared to QCTPro MIAF-Spine uses an automated 3D segmentation and an anatomic vertebral coordinate system to position a variety of analysis VOIs. This results in better precision than the more manually assisted analysis used by QCTPro. In-vivo precision errors will be approximately 0.5% higher compared to the analysis precision errors reported here (13). The results demonstrate that with 3D QCT in-vivo precision errors of about 1%-1.5% for trabecular and 2.5% to 3% for cortical bone can be obtained in postmenopausal women.
