Fig. 3From: Investigation of PET image quality with acquisition time/bed and enhancement of lesion quantification accuracy through deep progressive learningQuantitative analysis of PET image reconstructed by OSEM and DPL algorithms. a–d are SBR, CBR, SNR and CNR, respectively, which change with acquisition time. DPL shows a significantly elevated in SBR, CBR, SNR and CNR compared to OSEM (all the paired p < 0.001), indicating the improvement of image qualityBack to article page
