What this Trial Is About
Researchers are evaluating a new dual-target imaging agent called 68Ga-RM26-RGD for PETCT scans in patients with breast, brain, and prostate cancers that express specific receptors GRPR and integrin v3. This study aims to improve tumor detection by comparing this agent with conventional 18F-FDG and single-target imaging agents, addressing limitations of current imaging methods in detecting tumors with low 18F-FDG uptake or variable receptor expression. Participants will undergo PETCT scans using intravenous injections of 68Ga-RM26-RGD and one of the comparator agents 18F-FDG, 68Ga-RM26, or 68Ga-RGD within a two-week period. The dosages for these agents are approximately 1.8-2.2 MBqkg. Each patient receives scans with both agents to compare imaging performance directly. During the study, researchers will assess diagnostic accuracy and dosimetry of 68Ga-RM26-RGD over about one year. Participants will have multiple PETCT scans and related evaluations to monitor uptake of the imaging agents in tumors. The study includes safety and diagnostic performance monitoring throughout the participation period.
