Region of interest (ROI) drawn over the right condyle to calculate the maximum, minimum, and average radiotracer uptake count on bone SPECT and facial CT-fused image. a Radiotracer count was calculated by ROI (3.0 × 3.0 × 3.0 pixel) on coronal image. b Radiotracer count was calculated by ROI (3.0 × 3.0 × 3.0 pixel) on 3 planes (axial, sagittal, coronal view). Right, left condyle, and clivus also calculated for the ratio in each subject
