Abstract:
ObjectiveTo investigate reproducibility of cardiac MRI for assessment of cardiac morphology and ventricular function in selected normal Chinese Han population.MethodsTwo hundred and sixty-nine normal volunteers underwent cardiac MRI using a 1.5 T MR system.HASTE and steady state free precession imaging were performed with long and short axis images and cine mode through the ventricle with wireless vector cardiac gating.The images were reviewed by two independent observers.The dimensions of cardiac chambers and ventricular function including ejection fraction (EF),end diastolic volume( EDV),end systolic volume (ESV) and myocardial mass were evaluated.The data between male and female were compared by using two-tailed unpaired t test.Results Total imaging time was (15 ± 3 ) min.The anteroposterior diameter of the left atrium was( 2.87 ± 0.77 ) cm,the right atrial diameter perpendicular to the atrial septum was ( 3.61 ± 0.57 ) cm,the end diastolic diameter of the left ventricle was (4.97 ±0.52) cm,the end diastolic diameter of the right ventricle was (2.65 ± 0.48) cm.On the left ventricle,EF was(60.62 ±7.08)％,EDV was (115.37 ±26.71) ml,ESV was (46.02+15.72) ml and LV mass was ( 82.97± 24.03 ) g.On the right ventricle,EF was (47.73 ± 6.50 ) ％,EDV was ( 128.27 ± 32.16 )ml,ESV was (67.7 ± 21.07) ml and RV mass was (48.24 ± 13.42) g.There were no statistically significant differences in LVESV( P =0.144 ),LVEDV index ( P =0.714 ),LVESV index ( P =0.113 ),LVCI ( P =0.199),RVEF ( P =0.296 ) and RV mass ( P =0.093 ),and statistically significant differences in other cardiac parameters between male and female.Conclusion Cardiac MRI can provide useful information about cardiac function and morphology with a high level of reproducibility in normal Chinese Han population.
