P value was corrected by Bonferroni's method for multiple testing. Az values represent area under ROC curve. Numbers in parentheses and brackets represent number of true- and false-positive lesions, respectively. *P values are BH-T2WI and RT-T2WI, BH-T2WI and MultiVane T2WI, RT-T2WI and MultiVane T2WI. BH-T2WI = breath-hold multi-shot T2-weighted image, PPV = positive predictive value, ROC = receiver operating characteristic, RT-T2WI = respiratory-triggered multi-shot T2-weighted image
