Fig. 4From: Voxel-based identification of local recurrence sub-regions from pre-treatment PET/CT for locally advanced head and neck cancersPercentage of GTVfailure (red line) and GTVresponder (blue line) covered by the MTV as a function of % SUVmax. The MTV covers a higher percentage of GTVfailure than GTVresponder for threshold values ranging from 15% to 80%. However, no threshold value allowed to cover most of GTVfailure without covering most of GTVresponder. GTVfailure recurrence volume within the primary tumor, GTVresponder responder volume within the primary tumor, MTV metabolic tumor volume, SUVmax maximum standard uptake valueBack to article page
