Is less more? The influence of the number of sequential SPECT acquisitions on the intra-therapeutic intra-renal effective half-life of 177 Lu-PSMA-617 in Radioligand Therapy (EANM 2026) - Sep 29, 2026 - Abstract #EP-1007; "A third SPECT-acquisition at 72 h p.i. might not add significant accuracy to kidney dosimetry compared to the calculation of the IREHL with two time points (24 h and 48 h p.i.). However, the influence of an even later SPECT-examination (e.g. 96 or 120 h) and its contribution to a more accurate calculation of IREHL and therefore of the kidney dose should be further investigated."
