Evaluation of Circulation, Γ, as a quantifying metric in 4D flow MRI
نویسندگان
چکیده
Background 4D flow MRI provide a wonderfully rich set of data for diagnosis and understanding of cardiac disease. Interpretation of this wealth of data can be challenging and it may be desirable to simplify it to make analysis manageable. We have observed interesting rotational behavior of blood in the aorta in a number of cardiac diseases. Circulation (Γ) is a metric used in fluid dynamics to quantify the rotational components of flow. This metric has not been reported before for 4D flow MRI and may provide a measurement that can be used diagnostically. The purpose of this work is to define the normal range of Γ in the ascending aorta and investigate its reproducibility.

Estimating the irreversible pressure drop across a stenosis by quantifying turbulence production using 4D Flow MRI
The pressure drop across a stenotic vessel is an important parameter in medicine, providing a commonly used and intuitive metric for evaluating the severity of the stenosis. However, non-invasive estimation of the pressure drop under pathological conditions has remained difficult. This study demonstrates a novel method to quantify the irreversible pressure drop across a stenosis using 4D Flow M...

Background Evaluation of blood flow characteristics in total cavo-pulmonary connection (TCPC) with CMR remains difficult due to its strong modulation by respiration, and is not yet entirely understood. New approaches using 4D phase contrast magnetic resonance imaging (4D PC MRI) are promising and can contribute to the understanding of hemodynamics in the Fontan Circulation. Our objective was to...
متن کامل4D flow imaging with MRI.
Magnetic resonance imaging (MRI) has become an important tool for the clinical evaluation of patients with cardiovascular disease. Since its introduction in the late 1980s, 2-dimensional phase contrast MRI (2D PC-MRI) has become a routine part of standard-of-care cardiac MRI for the assessment of regional blood flow in the heart and great vessels. More recently, time-resolved PC-MRI with veloci...

Target audience: Researchers and clinicians interested in 4D flow for non-invasive assessment of mesenteric circulation and portal hypertension. Introduction: Portal hypertension is an end-stage complication of cirrhosis that leads to dramatic and complex alterations in the hemodynamics of the hepatic and the mesenteric circulation. Currently, there are few valid quantitative biomarkers to asse...
