Evaluation of Real‐Time Cardiovascular Flow MRI Using Compressed Sensing in a Phantom and in Patients With Valvular Disease or Arrhythmia

Journal of Magnetic Resonance Imaging, EarlyView.
Background Real‐time (RT) phase contrast (PC) flow MRI can potentially be used to measure blood flow in arrhythmic patients. Undersampled RT PC has been combined with online compressed sensing (CS) reconstruction (CS RT) enabling clinical use. However, CS RT flow has not been validated in a clinical setting.

Quantitative Evaluation of Carotid Artery Stenosis by Multi‐VENC 4D Flow MRI: Incorporating Turbulent Kinetic Energy for Clinical Validity

Journal of Magnetic Resonance Imaging, EarlyView.
ABSTRACT Background Cervical internal carotid artery stenosis (ICS) is a recognized risk factor for ischemic stroke, yet morphological severity alone may not fully reflect hemodynamic alterations. Turbulent kinetic energy (TKE), derived from multi‐velocity‐encoding (multi‐VENC) four‐dimensional (4D) flow MRI, may provide a robust marker for ICS ...

Influence of Field Strength, Sex, and Age on Pseudo‐Continuous Arterial Spin Labeling and T1 Mapping in the Kidney

Journal of Magnetic Resonance Imaging, EarlyView.
ABSTRACT Background Pseudo‐continuous arterial spin labeling (PCASL) and T1 mapping have been used for renal imaging at 1.5 T and 3 T. However, direct comparisons between field strengths, age, and sex are lacking. Purpose To assess the effects of field strength, age, and sex on renal perfusion and T1 values and measure reproducibility.
