Correlation analysis showed no significant
relationship between IVIM-DKI and PET parameters. IVIM parameters with Total-Variation
model produced substantial reproducibility with better quality parameter maps.
Figure2 (a) SUV map, (b) ADC map, (c, k) DKI parameter maps, (d, e) diffusion parameters
and (g-j) perfusion parameters from IVIM analysis of a 32-year-old male was
diagnosed for NHL; the tumour was present in sternum encircled in red.
Figure1 PET images (red) overlapped onto ADC images of a patient with NHL, where the tumour is encircled (green). (a) to (g) represents
baseline scans at axial view. (h) Representative 3D sagittal view with lines
indicating slices (a-g) selected for visualization.
