 AB    The degree of valvular regurgitation was measured by dynamic magnetic
       resonance imaging (MRI) and colour-Doppler echocardiography (CDE) in 23
       patients (14 men, 9 women; mean age 53 [19-75] years) with aortic (n =
       13) or mitral (n = 10) regurgitation. Quantification by MRI was from a
       section corresponding to the four-chamber view. In aortic regurgitation,
       maximal regurgitant jet area (JA), ratio of JA to left-ventricular area
       (JA/LVA) were measured, while in mitral regurgitation, the ratio of JA
       to left atrial area (JA/LAA) was measured, as well as jet volume (JV)
       and the ratio of JV to the corresponding volume of the receiving chamber
       (JV/LVV or JV/LVA). The results were compared with corresponding
       measurement obtained by CDE in the four-chamber view. The degree of
       regurgitation was graded as small if JA/LVA or JA/LAA, respectively, was
       less than 0.2, moderate if 0.2-0.4, and marked if more than 0.4. In the
       patients with aortic regurgitation the correlation between the two
       methods was r = 0.91 regarding the jet area, 0.93 regarding JA/LVA and
       0.92 regarding JV/LVV and JA/LVA. For mitral regurgitation the r values
       were 0.93 for JA, 0.89 for JA/LAA, and 0.85 for JV/LAV to JA/LAA. The
       grading of aortic regurgitation by MRI and CDE agreed in 12 of 13
       patients (92%), and in nine of ten (90%) with mitral regurgitation
       (deviation by one degree of severity in each). These data indicate that
       quantification of aortic and mitral regurgitation gives similar results
       with MRI and CDE: thus, MRI is an equal substitute to CDE in patients
       with inadequate conditions for sonography.
