To explore the value of phase ordering with automatic window selection(PAWS)and simultaneous multiple volume(SMV)algorithm double respiratory navigator-gated two-dimensional(2DNAV)dual inversion recovery(DIR)fast spin echo(FSE)high-resolution black-blood coronary artery wall magnetic resonance imaging(MRI)and evaluate its advantages and limitations. PAWS and SMV 2DNAV DIR FSE high-resolution black-blood MRI was performed in 21 healthy volunteers. The images were evaluated qualitatively by using four grades(grade 0can not evaluate;grade 1bad;grade 2good;grade 3perfect). Images defined as grade 0 and grade 1 were excluded and those defined as grade 2 and 3 were evaluated further. Thickness of proximal(or middle)segment of right coronary artery(RCA)and left anterior descending branch(LAD)were measured. The difference of wall thickness was analyzed by using two-tailed independent sample t-test. P values of less than 0.05 were considered statistically significant. Among the 38 slice images,31 slices(RCA13 slices,L
