From: Can a penalized-likelihood estimation algorithm be used to reduce the injected dose or the acquisition time in 68Ga-DOTATATE PET/CT studies?

Fig. 7

Representative coronal 68Ga-DOTA images of patient no. 1 reconstructed with Hadassah (1.5, 1.0 and 0.5 min/bp) and manufacturer recommendation GE OSEM (1.5 min/bp) and, Q.Clear, for 1.5, 1.0 and 0.5 min/bp and β = 1500, 1700 and 3000, respectively. The image quality of Q.Clear with 1.0 and 0.5 min/bp is better compared to Hadassah OSEM with the same acquisition time and is similar when using 1.5 min/bp. The image quality seems better with Q.Clear than for GE OSEM for all acquisition times. SUVmax uptake values (g/ml) obtained with the different reconstruction methods for two lesions are indicated by arrows. The gray scales next to the images represents the corresponding SUV scale in g/ml
