To determine the accuracy of visual analysis of left ventricular(LV) function in comparison with the accepted quantitative gold standard method, Cardiac Magnetic Resonance (CMR). Cine CMR imaging was performed at 1.5 T on 44 patients with a range of ejection fractions (EF, 580%). Clinicians (n = 18)were asked to visually assess EF after sequentially being shown cine images of a four chamber(horizontal long axis; HLA), two chamber (vertical long axis; VLA) and a short axis stack(SAS)and results were compared to a commercially available analysis package. There were strong correlations between visual and quantitative assessment. However, the EF was underestimated in all categories (by 8.4% for HLA, 8.4% for HLA ? VLA and 7.9% for HLA ? VLA ? SAS, P all\0.01) and particularly underestimated in mild LV impairment (17.4%, P\0.01), less so for moderate (4.9%) and not for severe impairment (1%). Assessing more than one view of the heart improved visual assessment of LV, EF, however, clinicians underestimated EF by 8.4% on average, with particular inaccuracy in those with mild dysfunction. Given the important clinical information provided by LV assessment, quantitative analysis is recommended for accurate assessment.
