Abstract EN
Background : In patients with coronary artery disease (CAD), assessment of viable myocardium has important prognostic implications.
The aim of this study was to compare contrast-enhanced magnetic resonance imaging (ce–MRI) with single–photon emission computed tomography (SPECT), using 99mTC–sestamibi for detection of myocardial viability.
Methods : Twenty-seven patients with coronary artery disease and an ejection fraction (EF) < 40% were enrolled.
For the ce–MRI, the segmental extent of hyperenhancement (SEH) was quantified after the administration of a gadolinium–based contrast agent, and for the SPECT a 4-hour redistribution protocol was used.
For the assessment of EF, we used echocardiography.
Comparison of viability assessment was performed in 1458 segments.
Results : Agreement between two modalities was obtained in 1332 (91.4%) segments, resulting in a kappa value of 0.8.
In 126 segments, we had discordant results.
102 SPECT viable segments were non-viable according to ce–MRI and 24 ce–MRI viable segments were described as non-viable by SPECT.
Conclusions : SPECT was comparable to ce–MRI for myocardial viability assessment, but we were not able to define which of them was superior.
