“…In Fig. This illustrates that the 1-dir MV-flow method, although readily applied in clinical studies (Kroft and de Roos, 1999;Rebergen et al, 1996), is not recommended for accurate transvalvular MV-flow measurement. The area with regurgitant flow is clearly discriminated.…”

A new method for quantifying the transvalvular flow through the mitral valve (MV) based on three-directional velocity-encoded magnetic resonance imaging (MRI) is presented. For thirty time phases during one cardiac cycle, the three-dimensional (3D) velocity vector field of the blood flow is reconstructed from the MRI measurement. Retrospectively, for each time phase, the MV-plane is indicated manually in the velocity data and the flow through this plane is determined, representing the MV flow. Measurements are performed in 10 healthy volunteers. The new method is compared to the conventional, one-directional velocity-encoded MRI method for which an acquisition plane is positioned at the mitral valve at end-systole and remains fixed during the acquisition. The flow measurements with the new method correlate very well with the flow measured in the aorta (r(p)=0.92, p<0.01), whereas the conventional method shows no statistically significant correlation (r(p)=0.15, p=0.68). The low differences between the flow measured at the MV and the flow in the aorta proves high accuracy of the new method. Also, the new method shows very low intra- and interobserver variation, proving the high reproducibility. Three-directional velocity-encoded MRI is a patient-friendly and easy-to-use method suitable for quantifying accurately and reproducibly the transvalvular MV flow.

“…32). Similar measurements can be performed by phasecontrast MRI (Mohiaddin et al 1990(Mohiaddin et al , 1991Mostbeck et al 1993;Galjee et al 1995;Kroft and de Roos 1999). An advantage of MRI over Doppler echocardiography is that MRI can quantify the flow through the entire valve area or vessel, in contrast to Doppler imaging, where flow and flow velocity are measured in a relatively small area of interest.…”

“…With the introduction of cine 2D phase-contrast MRI in 1986 (124), flow imaging could become part of routine MRI. In the 1990s, several papers published in Acta Radiologica reported the use of phase-contrast velocity mapping in different applications such as measurement of aqueductal CSF flow (125,126), blood flow in the superior sagittal sinus (127), renal arteries (128), and biventricular diastolic flow (129). As documented in Acta Radiologica, velocity encoded phase contrast imaging has become an important part of cardiac MRI in congenital heart disease (130,131), and the technique can also be used for estimation of vessel wall shear stress (132,133).…”

The first reports in Acta Radiologica on magnetic resonance imaging (MRI) were published in 1984, four years after the first commercial MR scanners became available. For the first two years, all MR papers originated from the USA. Nordic contributions started in 1986, and until 2020, authors from 44 different countries have published MR papers in Acta Radiologica. Papers on MRI have constituted, on average, 30%–40% of all published original articles in Acta Radiologica, with a high of 49% in 2019. The MR papers published since 1984 document tremendous progress in several areas such as magnet and coil design, motion compensation techniques, faster image acquisitions, new image contrast, contrast-enhanced MRI, functional MRI, and image analysis. In this historical review, all of these aspects of MRI are discussed and related to Acta Radiologica papers.
