Assessment left and right ventricular functions by cine magnetic resonance imaging in healthy volunteers / 中华心血管病杂志

ABSTRACT

<p><b>OBJECTIVE</b>Left and right ventricular functions were assessed by cine MR imaging in comparison with echocardiography in healthy volunteers.</p><p><b>METHODS</b>A total of 36 healthy volunteers were examined with breath-hold true FISP cine MR imaging sequence and amended localize methods for left and right ventricular functions. Echocardiography (echo) was also performed in these volunteers.</p><p><b>RESULTS</b>(1) left ventricular global function parameters obtained by MR were as follows EDV (101.3 +/- 19.2) ml, ESV (42.1 +/- 13.3) ml, SV (69.2 +/- 9.8) ml, EF (59.1 +/- 7.2)%; Right ventricular global function as follows EDV (118.9 +/- 27.1) ml, ESV (57.6 +/- 16.1) ml, SV (61.2 +/- 12.7) ml, EF (51.9 +/- 4.5)%. (2) EDV measured by MR and echo was similar and ESV measured by MR was significantly higher and the rest parameters were lower than that by echo. There was a good correlation (r = 0.66 - 0.80, P < 0.05) on all parameters obtained by MR and echo.</p><p><b>CONCLUSION</b>The present study suggests that cine MR imaging is well applicable to left and right ventricular function and RV volume measurements.</p>
