Photon-counting computed tomography (PCCT) is a new advanced imaging technique that offers improved spatial and contrast resolution, reduced image noise and artifacts, reduced radiation exposure, and multi-energy/multi-parametric imaging based on tissue properties. It has the potential to transform the standard clinical use of computed tomography (CT) imaging.
Photon-counting computed tomography (PCCT) is a new advanced imaging technique that is going to transform the standard clinical use of computed tomography (CT) imaging. Photon-counting detectors resolve the number of photons and the incident X-ray energy spectrum into multiple energy bins. Compared with conventional CT technology, PCCT offers the advantages of improved spatial and contrast resolution, reduction of image noise and artifacts, reduced radiation exposure, and multi-energy/multi-parametric imaging based on the atomic properties of tissues, with the consequent possibility to use different contrast agents and improve quantitative imaging. This narrative review first briefly describes the technical principles and the benefits of photon-counting CT and then provides a synthetic outline of the current literature on its use for vascular imaging.
