TL;DR: In this article, a newly developed photon counting detector with a gallium arsenide sensor, which enables imaging with higher quantum efficiency, and compare it with a silicon-based photon counting and a scintillation-based charge integrating detector.

TL;DR: The method has the potential to discriminate coagulated blood directly from contrast agent extravasation within a single CT acquisition and the additional inclusion of the dark-field signal for three-material decomposition qualifies the method for implementation into existing diagnostic routines.

TL;DR: In this article, the potential of x-ray dark-field radiography for the noninvasive detection of monosodium urate (MSU) crystals as a novel diagnostic tool for gout was evaluated.

TL;DR: In this paper, the authors demonstrate that dark-field X-ray radiography can detect naturally developed gout in animals with high diagnostic sensitivity and specificity based on the in situ measurement of monosodium urate (MSU) crystals.

TL;DR: X-ray dark-field radiography enables the detection of MSU crystals in a mouse-based gout model and simultaneous avaliability of a conventional attenuation image together with thedark-field image provides excellent detection rates of gout deposits with high specificity.
