Reference value of left and right atrial size and phasic function by SSFP CMR at 3.0 T in healthy Chinese adults

Abstract The size and function of the left atrium (LA) and right atrium (RA) are related closely with the prognosis of cardiovascular diseases. However, their normal reference values, as measured by cardiac magnetic resonance (CMR), are not well established in Chinese populations. Healthy Chinese su...
