Evaluation of elastix-based propagated align algorithm for VOI- and voxel-based analysis of longitudinal 18F-FDG PET/CT data from patients with non-small cell lung cancer (NSCLC)

EJNMMI Research

Table 1 Alignment percentage per patient between elastix and baseline image of intra- and extra-thoracic measurable lesions

N, number of measurable lesions per patient; % ΔSUV, percentage of the voxels that fall within the 95% limits of agreement of −1.46 to 1.46 ΔSUV; % Δ% perc., percentage of the voxels that fall within the 95% limits of agreement of −25 to 25 Δ percentage; CR, complete response; PR, partial response; SD: stabile disease; PD, progressive disease; −, no extra-thoracic lesions present. *Misalignment caused by adjacent normal tissue. **Patient with a solitary metastasis post curative surgical treatment. RECIST 1.1 response assessment.
