Overview

This is an open-label whole-body PET/CT study for investigating the value of Al18F-octreotide PET/CT in patients with SSTR positive tumors

Detailed description

Octreotide is an artificial replacement for the natural growth hormone inhibitor in humans. It is a small peptide hormone consisting of 14 amino acids and is widely distributed in neuroendocrine cells, with the highest density in the brain, peripheral neurons, endocrine pancreas and gastrointestinal tract. Under pathological conditions, some tumour cells show overexpression of growth inhibitory receptors, such as endocrine tumours of the pancreas, pituitary adenomas, pheochromocytomas, paragangliomas, carcinoid tumours, medullary thyroid carcinomas, small cell lung carcinomas Hepatocellular carcinoma, and meningioma. Therefore, the sensitivity and specificity of octreotide imaging is high.

This study will provide a visual, reproducible and non-invasive imaging method for the diagnosis of SSTR positive tumors through Al18F-octreotide PCT/CT imaging, providing an intuitive and clear imaging basis for clinical diagnosis, differential diagnosis and treatment, contributing to the development of medicine and science in the field of positron imaging.
