Compared to this dynamic [18F]FDOPA PET acquisition, the simplified protocol consists of a brief single-frame acquisition (10–15 min) and a simplified index of FDOPA uptake (standardised uptake value ratio (SUVRc)), defined as the ratio of the tracer activity in the striatum to that of...
Figure 1. Visualization of a simulated digital phantom (simDP) and simulated FBP (simFBP) from the data simulation pipeline using T1-MRI and the LDM-RR generated synthetic super-resolution FBP. 2.3. LDM-RR: PET Resolution Recovery Framework We use a latent diffusion model to generate syntheti...
(21 subsets, 2 iterations). The image matrix was 200 × 200 with a voxel size of 4.07 × 4.07 × 3.0 mm3. The volume of interest (VOI) for the breast lesion was delineated on PET images using a threshold of 2.5 of the maximum standardized uptake value (SUVmax) in MIM version 6.4 ...
