The total duration of this study was 5 months. The second phase was conducted four weeks after the first phase. Tables 1 and 2 present the contrast attenuation of the DDFT and palmar arteries at each site. HUpost was significantly higher than HUpre except for five measurements (site 3 in Group A, site 2 in Group B, site 3 in Group C, site 4 in Group F, and site 2 in Group G). Additionally, median HUpost was significantly higher than median HUpre in all groups.
