Application of radical dendrimers as organic radical contrast agents for magnetic resonance imaging

Autor: Chenyu Tian, Songbai Zhang, Vega Lloveras, José Vidal Gancedo

Publikováno v: Advanced Industrial and Engineering Polymer Research, Vol 7, Iss 2, Pp 255-261 (2024)

To develop metal-free magnetic resonance imaging (MRI) contrast agents, organic radical based contrast agents have been proposed as a promising alternative to obtain less toxic and safer MRI contrast agents. However, the low relaxivity and rapid in v

Radical Dendrimers Based on Biocompatible Oligoethylene Glycol Dendrimers as Contrast Agents for MRI

Autor: Songbai Zhang, Vega Lloveras, Daniel Pulido, Flonja Liko, Luiz F. Pinto, Fernando Albericio, Miriam Royo, José Vidal-Gancedo

Publikováno v: Pharmaceutics, Vol 12, Iss 8, p 772 (2020)

Finding alternatives to gadolinium (Gd)-based contrast agents (CA) with the same or even better paramagnetic properties is crucial to overcome their established toxicity. Herein we describe the synthesis and characterization of entirely organic metal

Metal-Free Radical Dendrimers as MRI Contrast Agents for Glioblastoma Diagnosis

Autor: Songbai, Zhang, Vega, Lloveras, Silvia, Lope-Piedrafita, Pilar, Calero-Pérez, Shuang, Wu, Ana Paula, Candiota, José, Vidal-Gancedo

Publikováno v: Biomacromolecules. 23(7)

Simultaneously being a nonradiative and noninvasive technique makes magnetic resonance imaging (MRI) one of the highly required imaging approaches for the early diagnosis and follow-up of tumors, specifically for brain cancer. Paramagnetic gadolinium
