I would like to measure the total lung SUV on Horos. Is it possible to segment lungs on CT and warp the segmented volume on the PET images to measure the total lung SUV?
Using LifeX software for PET-CT images can be quite useful. LifeX has modules prepared for SUV. It is also possible to perform automatic segmentation by determining the "Threshold" with this program. You can segment all lesions volumetrically with these modules. You can take what you want to work with and eliminate others.
