Virtual Noncontrast Imaging with Deep-Silicon Photon-Counting CT: Matched Phantom and Initial Human Evaluation

Multi-Contrast Deep-Silicon Photon-Counting CT for Post-Embolization Imaging: A Quantitative Phantom Study

Quantitative Comparison of Virtual and True Noncontrast Lung Images in Photon-counting CT: Global and Regional Attenuation Assessment.

Background Use of virtual noncontrast (VNC) images from photon-counting CT (PCCT) may reduce radiation dose and support quantitative lung analysis by obviating the need for separate true noncontrast (TNC) acquisitions. Their accuracy for lung densitometry, however, has not been systematically assessed. Purpose To evalu...

Image Quality of Non-Contrast Neurological Images on Energy-Integrating versus Silicon Photon-Counting Detector CT.

The purpose of this work was to evaluate image quality of non-contrast neurological CT scans on a commercially available energy-integrating detector (EID) CT compared to a prototype deep silicon (dSi) photon-counting detector CT (PCCT). A cohort of subjects scanned on the EID-CT (Apex CT, GE HealthCare, Waukesha, WI) w...

Single-Acquisition Spectral and Ultra-High-Resolution Pediatric Head CT: Phantom Comparison of Deep-Silicon Photon-Counting and Energy-Integrating Detectors

Current Medical Imaging

Electron density provides a significantly better CNR for liver metastases with electron density derived from dual-energy computed tomography compared with both conventional and VMI at 40 keV reconstructions, in both the unenhanced and portal-dominant phases.

Photon-counting detector CT with virtual monoenergetic imaging and iterative metal artifact reduction for spinal fusion implants: optimal keV and combined benefits.

For spinal implants, PCD-CT offers effective approaches for metal artifact and 120 keV is preferred and the combination of iMAR and 120 keV introduce new artifacts and requires careful consideration.
