Novel 1H/19F double‐tuned coil using an asymmetrical butterfly coil

Medical Physics, EarlyView.
Abstract Background: Fluorine‐19 (19F) magnetic resonance imaging (MRI) is a non‐invasive imaging tool for the targeted application of fluorinated agents, such as cell tracking, and for the demonstration of oximetry. However, as the SNR of 19F is significantly weaker than that of proton (1H) imaging, the 19F coil must be combined with 1H coils for ...

Myocardial perfusion mapping with intra‐arterial spin labeling: Optimization of the labeling efficiency

Magnetic Resonance in Medicine, EarlyView.
Abstract Purpose Intra‐arterial spin labeling (iASL) applies a labeling pulse from a transmit coil at the tip of the catheter for regional myocardial perfusion measurements during MR‐guided catheterizations. This study investigates the labeling efficiency of catheter‐mounted coils under varying conditions to enable robust iASL measurements. Methods The

Avian diversity changes in traditional agricultural landscapes of Japan over ten years

Oikos, EarlyView.
Agricultural intensification is a leading cause of biodiversity loss worldwide. However, the traditional agroecosystems are often associated with high avian diversity because of their landscape heterogeneity, offering available niches to different bird species.

Adaptive sampling for ecological monitoring using biased data: a stratum‐based approach

Oikos, EarlyView.
Indicators of biodiversity change across large extents of geographic, temporal and taxonomic space are frequent products of various types of ecological monitoring and other data collection efforts. Unfortunately, many such indicators are based on data that are highly unlikely to be representative of the intended statistical populations.

Prey and prejudice: predation by the European bee‐eater Merops apiaster has species‐specific effects on the ecology and genetics of bumblebees

Oikos, EarlyView.
Predation is a major ecological force, but its effect on bees has rarely been studied. Here, we investigated whether the presence of the European bee‐eater Merops apiaster, a migratory bird species and major bee predator, decreases the abundance and body size of three common bumblebee species (Bombus lapidarius, B. terrestris and B.
