TL;DR: A CT system with energy detection capabilities is presented, which was used to demonstrate the feasibility of quantitative K-edge CT imaging experimentally and derive a phenomenological model for the detector response and the energy bin sensitivities.

TL;DR: Investigation of spectral computed tomography used in combination with a gold high-density lipoprotein nanoparticle contrast agent with Au-HDL found it to be primarily localized in the macrophages on the aorta sections; hence, the multicolor CT images provided information about the Macrophage burden.

TL;DR: The first ex vivo images of fresh, native breast tissue obtained from mastectomy specimens using grating interferometry are presented, presenting improved diagnostic capabilities when compared with conventional mammography, especially when discerning the type of malignant conversions and their breadth within normal breast tissue.

TL;DR: This study investigated whether spectral computed tomography has the potential to improve luminal depiction by differentiating among intravascular gadolinium-based contrast agent, calcified plaque, and stent material by using the characteristic k edge of gadolinia.

TL;DR: It is now well understood that the sensitive detection and quantification of small intravascular thrombus in coronary arteries with molecular imaging techniques could provide a direct metric to diagnose and risk stratify patients presenting with chest pain.
