Ga-68-labeled prostate-specific membrane antigen (PSMA) ligands have been used clinically for positron emission tomography (PET) imaging of prostate cancer. However, F-18-labeled compounds offer several advantages, including the potential for delayed imaging, high starting activities enabling multidose preparation, and improved spatial resolution in PET.(More)
Since prostate-specific membrane antigen (PSMA) has been identified as a diagnostic target for prostate cancer, many urea-based small PSMA-targeting molecules were developed. First, the clinical application of these Ga-68 labelled compounds in positron emission tomography (PET) showed their diagnostic potential. Besides, the therapy of prostate cancer is a(More)
Functional nanoparticles are highly interesting imaging agents for positron emission tomography (PET) due to the possibility of multiple incorporation of positron emitting radionuclides thus increasing the signal strength. Furthermore, long-term nanoparticle biodistribution tests with increased signal-to-noise ratio can be achieved with nanoparticles(More)
Dear Sir, It was with particular interest that we read the article by Afshar-Oromieh et al. [1]. The authors developed a novel Ga-labelled prostate-specific membrane antigen (PSMA)binding small molecule, combining the well-known ureabased inhibitory motif glutamate-urea-lysine [2] with the lipophilic N,N′-bis[2-hydroxy-5-(carboxyethyl)-benzyl](More)
The biodistribution of 89Zr-labeled mesoporous silica nanoparticles (MSNs) was evaluated in detail using a prostate cancer mouse model bearing LNCaP C4-2 and PC-3 tumor xenografts with focus on passive targeting. PEGylation of radiolabeled MSNs significantly improved the blood circulation times and radically enhanced the accumulation in tumors comparable to(More)
