[Determination of the ejection fraction and cardiac volumes using magnetic resonance tomography].
The results of NMR-tomography and radiocontrast ventriculography (VG) were compared in 20 CHD patients to determine ejection fraction (EF), and left ventricular (LV) end-diastolic and end-systolic volumes (EDV and ESV). NMR-tomography of the heart was performed at the field power of 0.23 T using the synchronization with ECG. Two methods of orientation of NMP-section on the LV long axis were employed. A sufficiently high correlation of NMR-tomography and VG findings in the determination of EF (r = 0.9) was obtained, low and insignificant--in the determination of EDV and ESV. Possible causes of differences between the results of both methods are under discussion.
