Photon-counting CT for hepato-bilio-pancreatic imaging: a qualitative head-to-head comparison with third-generation dual-source CT: preliminary results.

Feasibility of low concentration iodinated contrast medium in portal venous abdominal imaging: performance of photon-counting CT virtual monoenergetic imaging compared to conventional EID-CT.

VMI at 45-50 keV provided the optimal balance of contrast and noise, supporting its potential clinical feasibility for routine portal venous phase abdominal imaging, and identifying the optimal keV range.

Clinical Photon-Counting CT in Neuroradiology: A Real-World Paired Comparison with Conventional Energy-Integrating CT.

BACKGROUND AND PURPOSE Photon-counting CT offers higher spatial resolution, improved contrast-to-noise efficiency, and spectral imaging, but its performance against heterogeneous EID-CT systems in routine use remains incompletely characterized. We compared image quality, pathology conspicuity, and radiation dose betwee...

Single-Phase Surrogate for True Non-Contrast Liver CT Using 190-keV Monoenergetic Imaging on Photon-Counting CT: Implications for Hepatic Steatosis Assessment.

190-keV VMI may serve as a practical surrogate for TNC in hepatic steatosis quantification, demonstrating reduced segment-dependent bias compared with VNC in artifact-prone regions.

Photon-counting detector CT for CT pulmonary angiography: a systematic review and meta-analysis.

Detection of hypodense hepatic and renal lesions on abdominal CT reconstructed with deep learning image reconstruction technique in patients with large body habitus: A multi-reader study.

In patients with large body habitus, DLIR-M and -H improved IQ and CNR with DLIR-H providing superior lesion conspicuity and diagnostic confidence; this study represents one of the first evaluations of DLIR performance in this specific patient population.

Ultra-High-Resolution Dual-Source Photon-Counting CT for Expanded Characterization of Pathophysiological Imaging Patterns in Multiple Myeloma.

RATIONALE AND OBJECTIVES Dual-source photon-counting CT (DS-PCCT) combines spectral imaging with ultra-high spatial resolution for whole-body assessment of multiple myeloma (MM). This study assessed axial and appendicular skeletal manifestations at initial diagnosis by exploiting attenuation characteristics of soft tis...
