Effect of Androgen Deprivation Therapy on Uptake of PSMA Ligand in Patients With Salivary Duct Carcinoma: an Explorative Study.

Explorative study, which evaluates the effect of androgen deprivation therapy (ADT) on the PSMA ligand uptake on 68Ga-PSMA-PET/CT in salivary duct carcinoma patients.

The Clinical Application of 68Ga-NOTA-exendin-4 PET/CT in Detecting Insulinoma

The small insulinoma can not be detected by the CT or MRI. We use 68Ga-NOTA-exendin-4 positron emission tomography/computed tomography (PET/CT) to detect the insulinoma for the patient diagnosed with endogenous hyperinsulinemic hypoglycaemia. And the diagnostic value will be performed. A single dose of 37-111 Mega-Becquerel (MBq) 68Ga-NOTA-exendin-4 will be injected intravenously. Visual and semiquantitative method will be used to assess the PET/CT images.

SMA-PET Imaging of Salivary Gland Tumours and Other Rare Cancers

The objectives of this pilot feasibility study, which is on the use of 68-Ga PSMA PET imaging of salivary gland tumours, are to determine the proportion of patients with high PSMA-ligand uptake on Ga-68 PSMA imaging in locally advanced, recurrent or metastatic salivary gland cancers and other rare cancer; and to determine if in vitro PSMA expression correlates to PSMA-ligand uptake on Ga-68 PSMA imaging in locally advanced, recurrent or metastatic salivary gland cancers and other rare cancers. The hypotheses of this study are that there is high PSMA-ligand uptake on Ga-68 PSMA imaging in locally advanced, recurrent or metastatic salivary gland cancers and other rare cancers; and that in vitro PSMA expression correlates to PSMA-ligand uptake on Ga-68 PSMA imaging.
