HYPER DPR reconstruction for fast PET scans

(A) Schematics of HYPER DPR.

(B) Representative body images reconstructed by OSEM and DPR with varied acquisition times. The locations of small lesions are highlighted by red circles.

(C and D) The SUV_max of the identified lesions (C) and SNR in the liver (D) for different methods. Statistical analyses on SUV_max are performed using repeated measures one-way ANOVA followed by Turkey’s multiple comparisons tests (n = 78). Statistical analyses on SNR are performed using Friedman tests followed by Dunnett’s multiple comparisons tests (n = 51). Asterisk represents two-tailed adjusted p value, with ∗p < 0.05, ∗∗p < 0.01, and ∗∗∗p < 0.001.
