Fig. 7From: Investigation of PET image quality with acquisition time/bed and enhancement of lesion quantification accuracy through deep progressive learningPET/CT image of a breast cancer patient. a and c are PET/CT fusion images reconstructed by OSEM and DPL, respectively; b and d are MIPs reconstructed by OSEM and DPL, respectively. A recurrence lesion (seen the arrow) after surgery with a maximal diameter of 0.87 cm was found in the left breast. The SUVmax of this lesion was 5.4 for OSEM, and 6.5 for DPLBack to article page
