“…A systematic review of 4D flow-derived methods for MR quantification identified seven studies that demonstrated that 4D flowderived MR volume is similar to that derived using standard CMR methods and even to that derived using 3D transoesophageal echocardiography (TOE) methods 29 . In one study, a standard CMR method for quantification of MR volume and 4D flow-derived methods yielded similar results 30 .…”

| Mitral regurgitation (MR) is a common valvular heart disease and is the second most frequent indication for heart valve surgery in Western countries. Echocardiography is the recommended first-line test for the assessment of valvular heart disease, but cardiovascular magnetic resonance imaging (CMR) provides complementary information, especially for assessing MR severity and to plan the timing of intervention. As new CMR techniques for the assessment of MR have arisen, standardizing CMR protocols for research and clinical studies has become important in order to optimize diagnostic utility and support the wider use of CMR for the clinical assessment of MR. In this Consensus Statement, we provide a detailed description of the current evidence on the use of CMR for MR assessment, highlight its current clinical utility, and recommend a standardized CMR protocol and report for MR assessment.

“…In addition, the multicenter reproducibility and test–retest reliability of 4D flow is another important aspect for its clinical applications and longitudinal investigations as well. Good reproducibility and low interobserver variability has been demonstrated for 4D flow MRI in the application of aorta, intraheart, intracranial arteries, and portal venous system . However, such investigation in the neurovascular system is still limited, especially for cerebral arteries.…”

Background 4D flow MRI shows great potential in neurovascular disorders such as stenosis, atherosclerotic disease, aneurysms, and vascular malformations. Its widespread application in the neurovascular system requires evidence of good test–retest multicenter reproducibility. Purpose To assess the multicenter reproducibility, test–retest reliability and interobserver dependence of 4D flow MRI in measurements of cerebral blood flow/velocity in main intracranial vessels. Study Type Prospective study. Subjects Ten healthy subjects underwent 4D flow scans at three different centers. All subjects were scanned twice at 2 different days at each center. Field Strength/Sequence 3.0 T; 4D flow sequence. Assessment Multicenter reproducibility, test–retest reliability and interobserver agreement for measurements of the blood flow and peak velocity from five regions of interest were assessed (bilateral internal carotid arteries, bilateral medial cerebral arteries, and sagittal sinus). Statistical Test A Shapiro–Wilks test was conducted to assess normality of measurements in each scan. Coefficient of variances (CVs) was computed to evaluate intra‐ and intersite variances of all measurements. The multicenter reproducibility was assessed by two‐way mixed intraclass correlation coefficient (ICC). A Bland–Altman plot and Pearson correlation were used to evaluate test–retest reliability. ICC was calculated to assess interobserver agreements. Results All P‐values for Shapiro–Wilks tests were greater than 0.05, which indicated the normality of all measurements. Both intra‐ and intersite CVs were lower than 12%. There was good test–retest reliability for both blood flow and peak velocity of all ROIs (r = 0.75–0.94). In addition, high multicenter reproducibility was detected (ICC = 0.77–0.96, all P < 0.001). The results of these measurements also showed great interobserver agreement (all ICC > 0.9 and all P < 0.001). Data Conclusion High multicenter reproducibility and test–retest reliability was shown for 4D flow in the measurements of blood flow and peak velocity of intracranial vessels. In addition, these measurements showed great interobserver agreement. Level of Evidence: 2 Technical Efficacy: Stage 1 J. Magn. Reson. Imaging 2019;49:1543–1552.

“…After substraction of the forward volume measured in the pulmonary artery from the total RV stroke volume assessed by RV volumetry (ciné steady-state free precession imaging), absolute TR regurgitant volume and fraction can be calculated (59). More recently, 4D-flow CMR has been used for 3D quantification of TR and can correct for through-plane motion as well as eccentricity, with high intra-and interobserver reproducibility and high consistency with 2D phase contrast velocity mapping and echocardiography (60,61).…”

With the emergence of transcatheter solutions for the treatment of tricuspid regurgitation (TR) increased attention has been directed to the once neglected tricuspid valve (TV) complex. Recent studies have highlighted new aspects of valve anatomy and TR etiology. The assessment of valve morphology along with quantification of regurgitation severity and RV function pose several challenges to cardiac imagers guiding transcatheter valve procedures. This review article aims to give an overview over the role of modern imaging modalities during assessment and treatment of the TV.
