By including flow sensitization gradients in SWI
sequence, signals from moving protons are suppressed, and dark
vessels are delineated at correct spatial locations.
Comparison
of GRE, GRE-FlowComp, and GRE-FlowSens images (left to
right columns). Magnetiude and mIP images were compared
to minIP images (top to
bottom rows). Incomplete flow compensation in GRE-FlowComp mis-registered vessels
at erroneous locations (arrow). GRE-FlowSens better delineates vessels.
Same
as Figure 1, but at an
inferior slice
location. GRE-FlowSens better delineates
vessels. Hypointensity segments in GRE-FlowComp can mimic
microhemorrhages in minIP (arrows).
