TL;DR: The high photon energy compared to existing liquid-metal-jet sources increases the penetration depth and allows imaging of thicker samples and the applicability of the source in the biomedical field is demonstrated by high-resolution imaging of a mammography phantom and a phase-contrast angiography phantom.

TL;DR: A laboratory method for imaging small blood vessels using x-ray propagation-based phase-contrast imaging and carbon dioxide (CO(2)) gas as a contrast agent and the limited radiation dose in combination with CO(2) being clinically acceptable makes the method promising for small-diameter vascular visualization.

TL;DR: In absorption, the method allows high-resolution tomographic skeletal imaging with potential for significantly shorter exposure times due to the power scalability of liquid-metal-jet sources and in phase contrast, the authors use a simple in-line arrangement to show distinct tumor demarcation of few-mm-sized tumors.

TL;DR: It is demonstrated that nanoparticle x-ray fluorescence computed tomography in mouse-sized objects can be performed with very high spatial resolution at acceptable dose and exposure times with a compact laboratory system and provides a possible path to in vivo molecular x-rays imaging at sub-100 μm resolution in mice.
