Coronary artery (CA) calcifications (CACs) connect upstream cardiovascular risks with downstream radiotherapy planning decisions, yet these powerful imaging biomarkers are underutilized in radiation oncology. We developed and validated an opportunistic screen...
To assess the accurate delivery of iodinated contrast media (ICM) and saline flush volumes administered using piston-driven and peristaltic power injectors.
To propose a clinically relevant, quantitative comparison of low-contrast edge definition on routine CT Head examinations.
Accurate musculoskeletal (MSK) CT assessment relies on high spatial resolution, which can be compromised when extremities are positioned away from the scanner isocenter. The purpose of this study is to evaluate the effect of off-center positioning on spatial...
To examine the subjective and objective image quality (IQ) of a deep learning image reconstruction algorithm (Precise Image Quality Engine (PIQE)) in abdominal CT.
Traditionally, CT scanner spatial resolution is characterized using non-clinically optimized scan modes (axial scans, with dose levels and kernels not suited for real patients). In this study, we demonstrate a clinically motivated approach for exploring how r...
Material quantification in spectral CT assumes a known voxel background, such as water in iodine maps or hydroxyapatite in bone edema maps. These assumptions are never met in vivo, where voxels typically contain mixtures of tissues with differing effective at...
