For131I- MIBG acquisition, 40 MBq radiopharmaceutical was injected. A whole body (4 cm/minute) and abdominal SPECT/CT acquisition were performed on MEDISO AnyScan SC system (Budapest, Hungary) 72 hours after the injection. SPECT parameters were: 1 minute/projection, 64 views, matrix size 64 × 64. A 16-slice CT was used, with 120 mAs and 120 kV abdominal filter. For the SPECT reconstruction OSEM method was performed. None of the adrenal regions showed abnormal focal uptake. MIBG: metaiodobenzylguanidine, SPECT: Single-Photon Emission Computed Tomography, CT: computed tomography, OSEM: Ordered Subset Expectation Maximization.
