#4630 Radiolabelled somatostatin receptor (SSTR) antagonist vs. agonist for peptide receptor radionuclide therapy (PPRT) in patients with SSTR positive neuroendocrine tumours – A retrospective basket study

Introduction: PRRT with lutetium-177 labelled somatostatin receptor (SSTR) agonists ([177Lu]Lu-DOTATATE or [177Lu]Lu-DOTATOC (177Lu-TOC) has limited response rate and durability. The SSTR antagonist [177Lu]Lu-DOTA-JR11 (177Lu-JR11) offers potentially increased tumour doses with better efficacy.

#4615 Dosimetry, efficacy and safety of radiolabelled somatostatin receptor antagonist in patients with metastatic pheochromocytoma or paraganglioma

Introduction: Metastatic pheochromocytomas and paragangliomas (mPPGLs) are rare neuroendocrine tumours with a heterogenous phenotype and a variable treatment response. The SSTR antagonist [177Lu]Lu177Lu-DOTA-JR11 (177Lu-JR11) offers potentially increased tumour doses than standard radioligand therapy (RLT) with [177Lu]Lu-DOTA-TOC (177Lu-TOC).

#4421 Head-to-head comparison of 18F-AlF-NOTA-JR11 PET/MR and 68Ga-DOTATATE PET/CT in patients with neuroendocrine tumours: A prospective study

Introduction: PET/MR combines the molecular advantages of PET with excellent morphologic and anatomic delineation of MRI.18F-AlF-NOTA-JR11, a novel SSTR antagonist with a high affinity for SSTR2, has the potential to perform better than SSTR agonists in neuroendocrine tumour imaging.

#3808 Comparison of [18F]AlF-NOTA-JR11 with [68Ga]DOTA-JR11 PET/MRI in models, mice, and neuroendocrine tumor patients

Introduction: Compared with [68]Ga, [18]F has the advantages of high production yield, shorter positron range, and favourable half-life allowing for centralized production and distribution to distant centers.

#3685 Somatostatin receptor imaging with difference positive rate of mice

Introduction: Majority of neuroendocrine neoplasms express SSTR2, and the pathological results of a single lesion cannot accurately reflect the expression of SSTR2 in other lesions because of heterogeneity.
