Web11 Dec 2024 · TEM analysis confirmed the 90 Zr atoms adsorption onto the SPION surface (≈ 10% average radial increase). Simultaneous PET-MR scans confirmed the capability of the [ 89 Zr]Zr-FH nano-platform for this multi-modal imaging technique. Relative contrast image analysis showed that [ 89 Zr]Zr-FH can act as a dual-mode T1/T2 contrast agent. WebDark-field radiography can generate high-resolution images of soft tissues, such as cartilage, tendons, and ligaments, which are typically challenging to visualise using conventional techniques. This capability can be invaluable in the early detection and management of musculoskeletal disorders.
