With the use of a dedicated RF coil and a modified pulse
sequence at 3T, we conducted high-resolution
non-contrast-enhanced time-of-flight MR angiography of
fingers on two normal subjects, and compared the results
with data acquired using the highest resolution we found
in finger MRA studies by other groups. Our
higher-resolution images give sharper and more
definitive depiction of the blood vessels, enabling
better visualization of the geometry and connectivity of
the blood vessels as well as the relationship between
the vessels. Our technique should be useful for the
diagnosis, treatment assessment and pathogenesis studies
of arthritis and systemic sclerosis.
