Case example of measurement of gadolinium ethoxy-benzyl diethylenetriamine pentaacetic acid (Gd-EOB-DTPA) uptake after radioembolisation. Regions of interest are placed in the left and right hepatic lobes (red circles), the spleen (not shown), and in the muscle in T1-weighted images obtained 20 min after Gd-EOB-DTPA, before (a) (baseline) and after RE (d) (follow-up). The measured mean signal intensities are used to calculate Gd-EOB-DTPA uptake according to Eqs. 1 and 2 (see the “Methods” section). The mean values at baseline (a) in RLL/LLL: LSR 1.9/1.9; LMR 1.8/1.8. The mean values measured at follow-up (d) in RLL/LLL: LSR 1.6/2.4; LMR 1.9/2.9. c The distribution of Y-90 microspheres in the right hepatic lobe in Bremsstrahlung SPECT/CT. b Baseline and e follow-up show the corresponding HBS SPECT/CT.
