BACKGROUND Various trivalent radiometals are well suited for labeling of DOTA-conjugated variants of Glu-ureido-based prostate-specific membrane antigen (PSMA) inhibitors. The DOTA-conjugate PSMA-617 has proven high potential in PSMA radioligand therapy (PSMA-RLT) of prostate cancer as well as PET imaging when labeled with lutetium-177 and gallium-68 respectively. Considering the relatively sho...

Positron Emission Tomography (PET) experienced accelerated development and has become an established method for medical research and clinical routine diagnostics on patient individualized basis. Development and availability of new radiopharmaceuticals specific for particular diseases is one of the driving forces of the expansion of clinical PET. The future development of the ⁶⁸Ga-radiopharmaceu...

Human recombinant epidermal growth factor (hEGF) was evaluated in various corneal wound healing models in the rabbit. Human EGF accelerated epithelial wound healing in corneal reepithelialization, anterior-keratectomy, and alkali-burn models at concentrations of 10-500 micrograms/ml given four times daily (qid). In the corneal reepithelialization model, 100 micrograms/ml of hEGF qid produced a ...

Rats affected by the MENX multitumor syndrome develop pheochromocytoma (100%). Pheochromocytomas are uncommon tumors and animal models are scarce, hence the interest in MENX rats to identify and preclinically evaluate novel targeted therapies. A prerequisite for such studies is a sensitive and noninvasive detection of MENXassociated pheochromocytoma. We performed positron emission tomography (P...

Background and purposeTo compare 68Ga-fibroblast activation protein inhibitor (FAPI) 18F-FDG PET/CT in imaging locally advanced oesophageal cancer, evaluate the potential usefulness of 68Ga-FAPI on gross target volume (GTV) delineation aimed at radiotherapy planning for cancer as compared with contrast-enhanced CT (CE-CT) PET/CT.Materials methodsTwenty-one patients newly diagnosed who underwent...
