Conditions

The study population includes all patients aged over 18 with a neuroendocrine tumor grade I and II and a clinical indication for PRRT.

Brief summary

The absorbed dose in target lesions measured on SPECT/CT imaging

Detailed description

The absorbed dose in normal tissue (kidneys, liver, spleen) measured on SPECT/CT imaging, The bone marrow dose is determined using blood withdrawals and SPECT/CT imaging, The uptake on SPECT/CT between target lesions and the liver and spleen measured on the 24 hours’ time point, The effect of continued LA-SSA use on specific population pharmacokinetic parameters will be qualified using population pharmacokinetic modelling using the acquired SPECT/CT scans and blood samples for dosimetry
