[Assessment left and right ventricular functions by cine magnetic resonance imaging in healthy volunteers]

Left and right ventricular functions were assessed by cine MR imaging in comparison with echocardiography in healthy volunteers.

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.

(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.

The present study suggests that cine MR imaging is well applicable to left and right ventricular function and RV volume measurements.
