Abstract: PurposeTo evaluate the in‐scan and scan–rescan consistency of left ventricular (LV) in‐ and outflow assessment from 1) 2D planimetry; 2) 4D flow magnetic resonance imaging (MRI) with retrospective valve tracking, and 3) 4D flow MRI with particle tracing.Materials and MethodsTen healthy volunteers (age 27 ± 3 years) underwent multislice cine short‐axis planimetry and whole‐heart 4D flow MRI on a 3T MRI scanner twice with repositioning between the scans. LV in‐ and outflow was compared from 1) 2D planimetry; 2) … Show more

“…4D flow magnetic resonance imaging (MRI) has been used for the evaluation of various challenging CHD types. Quantitative measures of flow perturbations using 4D flow can aid in surveillance and treatment decision‐making, and have been shown to be similar to standard clinical 2D phase‐contrast (PC) MRI with acceptable test–retest repeatability . Using 4D flow, it is possible to assess flow volume in large thoracic vessels, comprising the pulmonary‐systemic shunt ratio (Qp/Qs), shunt flow, peak flow, valvular regurgitant flow, and collateral flow volumes.…”

“…The same scanning protocol was performed twice in the same session with 10-min breaks between the scans and repositioning and replanning for every volunteer. Ten of these volunteers were included in a recent study [14]. That study did not report assessment of KE, EL or vorticity.…”

“…Papillary muscles were disregarded and assumed to be included in the ventricular volume. LV in-and outflow was assessed using the 4D flow MRI data with retrospective valve tracking of the mitral and aortic valve, as shown in a recent study [14]. Cardiac output (CO) was computed from the 4D flow data as LV outflow × Heart rate (HR).…”
