Portal hypertension (PH) is currently diagnosed by the hepatic venous pressure gradient (HVPG). Subharmonic imaging (SHI) is a contrast-enhanced ultrasound (CEUS) imaging technique receiving at half the transmit frequency resulting in better tissue suppressio...

To evaluate image quality in neonatal brain CT using a custom phantom designed to replicate clinically relevant skull and soft tissue attenuation, enabling assessment of contrast-to-noise ratio (CNR) for improved diagnostic confidence in pediatric neuroimagin...

Deep silicon photon counting CT can produce quantitative CT images with every scan, leveraging 8 energy bins to quantify material densities. This study evaluates the material decomposition (MD) and virtual monoenergetic image (VMI) accuracy of calcium and iod...

To quantify low-contrast detectability (LCD) of deep silicon-based PCCT (dSi-PCCT) compared to energy-integrated detector (EID) CT using task-based image quality metrics—Receiver Operating Characteristic (ROC) area under the curve (AUC) and detectability inde...

Direct imaging of Y‑90 bremsstrahlung with SPECT remains challenging because the continuous photon energy spectrum introduces scatter and septal penetration which reduces contrast and complicates quantitative reconstruction. Optimal energy‑window placement is...

To validate a high-throughput workflow for quantifying liver proton-density fat-fraction (PDFF), using a novel two-door/two-bed MRI suite and a focused, AI-assisted, motion-insensitive chemical-shift-encoded (CSE) MRI protocol.

Glutathione (GSH) is a primary antioxidant in the human brain, supporting cognitive function. Detection of GSH in vivo by 1H MRS requires spectral editing due to large overlapping signals from other metabolites. Multiple quantum coherence (MQC) technique prov...
