Fig. 4From: Deep learning-assisted PET imaging achieves fast scan/low-dose examinationTransverse images showing lymph node metastasis of a 61-year-old female patient with colorectal cancer. The upper and bottom row were reconstructed with GS and HYPER DLR algorithm, respectively. The acquisition time is 180, 135, 90, and 60 s (left to right). The bottom row indicates a performance equivalent to the one in the upper row regarding lesion detection with decreased image noise in the surrounding tissueBack to article page
