TL;DR: The imaging properties of Medipix2 MXR multi-chip assemblies bump bonded to 1 mm thick CdTe sensors are described and the finding that higher maximum count rates come at the cost of a reduced energy resolution is concluded.

TL;DR: The volume and changes of human brown adipose tissue (BAT) in vivo following exposure to cold using magnetic resonance imaging (MRI) are evaluated.

TL;DR: The authors' results indicate that nonlinearity corrections may be feasible only when the K-edge of interest is sufficiently high compared to the mean photon energy, and that spectroscopic CT at high x-ray fluxes may suffer from less limitations when using high-Z materials as contrast agents.

TL;DR: In this article, the authors examined the imaging properties of Medipix2 MXR arrays under high photon fluxes and showed that the critical photon flux, at which the detector's linear response breaks down, can be shifted towards higher values by increasing the IKrum current in the charge sensitive preamplifier, which corresponds to reducing the pulse shaping time.

TL;DR: Direct [(1)H]-(31)P imaging using FreqSel as well as MP-Dixon is possible in clinically feasible acquisition times andFreqSel should be preferred for measurements where only a single metabolite resonance is considered.
