Validation of aorta diameter measurement based on centreline planes. Aorta diameter determined by three different methods: (i) manual measurements based on standard multi-planar CE-MRA (black dots and bars representing mean and standard deviation), (ii) centreline-based automatic diameter detection using PC-MRA (yellow dots and bars representing mean and standard deviation), and (iii) centreline-based automatic diameter detection using CE-MRA (grey dots and bars representing mean and standard deviation) for 20 subjects were used to validate centreline-based diameters. Red dots indicate significant differences (P < 0.05, independent-sample t-test) between centreline-based CE-MRA and PC-MRA diameters.
