Inter-session coefficients of variance (CV) of GRE images. In RF shimming, the inter-session CV is significantly lower in BH than FB (a, P < 0.01). The CV is also significantly lower in BH than FB in RF design (b, P < 0.05). Note that CVs of qTx are smallest and significantly different to FB and BH, both for RF shimming and RF design. *P < 0.01, †P < 0.05; BH, breath-holding; FB, free-breathing; GRE, gradient echo; RF, radiofrequency; qTx, quadrature transmission; RF, radiofrequency.
