Figure 5

(A,B) Box plots of the absolute and relative maximum helical volume (HVmax) in [ml] and [%] demonstrated no significant differences at 1.5 T and 3 T in volunteers. (C,D) Box plots of the absolute and relative maximum helical volume (HVmax) in [ml] and [%] demonstrated significantly higher values in patients as compared to volunteers. The difference of the relative HVmax is less pronounced as with the absolute values. n.s. = no significant differences; *significant differences.
