Iron Oxide Nanoradiomaterials: Combining Nanoscale Properties with Radioisotopes for Enhanced Molecular Imaging [PDF]

Contrast Media & Molecular Imaging, 2017
The combination of the size-dependent properties of nanomaterials with radioisotopes is emerging as a novel tool for molecular imaging. There are numerous examples already showing how the controlled synthesis of nanoparticles and the incorporation of a radioisotope in the nanostructure offer new features beyond the simple addition of different ...

Comparison between three radioisotope methods for measuring iron absorption. [PDF]

BMJ, 1967
The present methods for determining iron absorption from the alimentary tract depend on the measurement by radioisotope techniques of iron retained in the body after oral administra tion. They vary in convenience and complexity, and some times require assumptions about iron metabolism for their interpretation. The first, the " faecal recovery " method,

Radiation makes cells select the form of death dependent on external or internal exposure: apoptosis or pyroptosis

Scientific Reports, 2023
Internal radiation exposure from neutron-induced radioisotopes environmentally activated following atomic bombing or nuclear accidents should be considered for a complete picture of pathologic effects on survivors. Acute and localized high dose radiation

Intraoperative laparoscopic detection of sentinel lymph nodes with indocyanine green and superparamagnetic iron oxide in a swine gallbladder cancer model.

PLoS ONE, 2021
Mapping of sentinel lymph nodes (SLNs) can enable less invasive surgery. However, mapping is challenging for cancers of difficult-to-access visceral organs, such as the gallbladder, because the standard method using radioisotopes (RIs) requires ...
