In all groups, scanning parameters were 80 kV and 250 mA;
HUpre: pre-contrast attenuation of the deep digital
flexor tendon (DDFT). HUpost: post-contrast attenuation
of the DDFT. HUmed: post-contrast attenuation of the
medial palmar artery (PA). HUlat: post-contrast
attenuation of the lateral PA. median HUpre: Median of
HUpre; median HUpost: median of
HUpos; median
HUpost-HUpre: median of the difference
between HUpre and HUpost; median
HUmed: Median of HUmed; median of
HUlat: median of HUlat.
