The Development and Challenges of PET/MRI Dual‐Modality Imaging Probes—An Update

Journal of Magnetic Resonance Imaging, EarlyView.
ABSTRACT The integration of Positron emission tomography (PET) with Magnetic resonance imaging (MRI) combines the functional imaging capabilities of PET with the high‐resolution anatomical detail of MRI, creating a synergistic platform for advanced diagnostic imaging and image‐guided therapies. Central to the success of this dual‐modality system is the

Macrofaunal contributions to benthic nutrient fluxes revealed by radium disequilibrium

Limnology and Oceanography, EarlyView.
Abstract The benthic flux of nutrients underpins marine food webs, influences conditions for life in the oceans, and contributes to climatic feedback. Estimates of these fluxes' contributions to macro‐ and micronutrient cycles are, however, highly variable, generating significant uncertainty in biogeochemical models.

Solid Target System with In-Situ Target Dissolution

Instruments, 2019
A significant number of medical radioisotopes use solid, often metallic, parent materials. These materials are deposited on a substrate to facilitate the cooling and handling of the target during placing, irradiation, and processing.

Future Supply of Medical Radioisotopes for the UK Report 2014 [PDF]

arXiv, 2015
The UK has no research nuclear reactors and relies on the importation of 99Mo and other medical radioisotopes (e.g. Iodine-131) from overseas (excluding PET radioisotopes). The UK is therefore vulnerable not only to global shortages, but to problems with shipping and importation of the products.
