In Vivo Dynamic Coronary Arteries Blood Flow Imaging Based on Multi‐Cycle Phase Clustering Ultrafast Ultrasound

Advanced Science
Echocardiography is the most primary clinical modality for dynamic cardiac imaging. However, the vigorous motion of myocardial tissue inherently causes inevitable signal aliasing between blood flow and myocardial tissue in traditional Doppler ultrasound ...

Pulmonary hypertension in adolescents with sickle cell disease [PDF]

, 2016
Sickle cell disease consists of a group of disorders that have a similar mutation in at least one of the beta-globin chains of hemoglobin. This results in a change of the hemoglobin to sickle shaped cells when in the deoxygenated state.

4D Flow MRI Velocity and Turbulence Mapping in Mild Valvular Heart Disease

Journal of Magnetic Resonance Imaging, EarlyView.
ABSTRACT Background Valvular heart disease (VHD) commonly leads to the development of turbulent blood flow. Turbulent kinetic energy (TKE), measured with 4D flow MRI, may be a complement to current metrics for early identification of VHD. Purpose To investigate TKE as a marker of VHD in relation to flow velocity and cardiovascular geometry.

ULTRA‐Metrics

Journal of Ultrasound in Medicine, EarlyView.
Objectives Ultrasound competency is critical in modern healthcare, yet no standardized framework currently supports ultrasound skill monitoring across diverse clinical settings and user types. Existing frameworks often lack generalizability, overemphasize exam counts, and fail to assess key skills such as interpretation, limiting ultrasound's safe and ...
