18F-FDG liver biodistribution in a patient affected by liver metastases and referred to PET/CT to restage the disease after systemic therapy. PET and Fusion images were evaluated applying the same SUVmax threshold. a Scan with reduced number of counts and standard acquisition (no processed image): highly inhomogeneous radiotracer uptake showing multiple focal uptakes that might be interpreted as metastases and thus, erroneously, as progressive disease. b Native scan (acquisition with increased time): regular distribution of the radiotracer leading to the correct identification of few metastatic lesions (scan correctly reported as stable disease). c Processed scan, obtained with reduced dose and processed by SubtlePET: regular radiotracer distribution in the liver, confirming the non-inferior quality of the image compared to native scan. The interpretation of these image lead to the same conclusion derived by the interpretation of the native scan (stable disease)
