Abstract Blood flow metrics obtained with four-dimensional (4D) flow phase contrast (PC) magnetic resonance imaging (MRI) can be of great value in clinical and experimental cerebrovascular analysis. However, limitations in both quantitative and quali

Aneurysm rupture has been suggested to be related to aneurysm geometry, morphology, and complex flow activity; therefore, understanding aneurysm-specific hemodynamics is crucial. 4D Flow MRI has been shown to be a feasible tool for assessing hemodyna

PURPOSE: To assess the effects of cardiovascular-induced motion on conventional diffusion-weighted imaging (DWI) of the pancreas, and to evaluate motion-robust DWI methods in a motion phantom and healthy volunteers. METHODS: 3T DWI was acquired using

Characterization of hepatic blood flow magnitude and distribution can lead to a better understanding of the pathophysiology of liver disease. However, the underlying patterns and dynamics of hepatic flow, such as the helical flow structure that often

To gain further insight into male–female differences in cardiovascular conditions it is important to understand sex differences in healthy populations. A previous study from our group of 39 healthy young volunteers (20–35 years) paradoxically fou

Introduction: Atrial fibrillation (AF) is a common cardiac rhythm disorder that is often comorbid with pulmonary hypertension (PH) and other conditions associated with abnormal atrial pressure and/or volume overload. In the setting of atrial dilation
