Figure 2:

Pictorial representation of visual Response Evaluation Criteria in Prostate-specific Membrane Antigen (PSMA) PET/CT (RECIP) and quantitative RECIP. RECIP combines changes in PSMA-positive total tumor volume (TTV) and the occurrence of new lesions. Changes in TTV can be determined quantitatively by using tumor segmentation software and combined with the occurrence of new lesions to calculate quantitative RECIP. Changes in TTV can be determined qualitatively by nuclear medicine physicians and combined with the occurrence of new lesions to calculate visual RECIP.
