In Vivo K-edge Imaging on a Clinical Dual-source PCCT: Feasibility of Gadolinium Applications in a Porcine Model

Objectives: To evaluate the feasibility of in vivo gadolinium K-edge imaging on a clinical dual-source photon-counting CT (PCCT) system in a porcine model and to assess its performance for dynamic contrast-enhanced imaging, functional biliary imaging, and dual-contrast (bi-phasic) imaging. Materials and Methods: A sing...

Deep Learning Reconstruction for Ultra-High-Resolution Photon-Counting CT of the Lung: Image Quality and Texture Characterization

Objectives: To characterize image noise, lesion contrast, spatial resolution, and attenuation distribution for deep learning reconstruction (DLR) compared with hybrid iterative reconstruction (IR) in ultra-high-resolution (UHR) photon-counting CT (PCCT) of the lung, using a patient-derived 3D-printed phantom, and to ap...

Deep Learning Reconstruction versus Hybrid Iterative Reconstruction for Spectral CT: A Multi-Institutional Image Quality Assessment

Purpose: To compare image quality between deep learning reconstruction and hybrid iterative reconstruction for conventional and virtual monoenergetic images derived from the same spectral CT examinations. Methods and Materials: This retrospective, post hoc secondary analysis of a multi-institutional, controlled, blinde...
