Which sequence of MRI is used to detect microhemorrhages?
T1WI
T2WI
SWI
DWI
SWI (Susceptibility-Weighted Imaging ) is a relatively new full-velocity compensated high-resolution 3-dimensional gradient echo sequence that accurately detects small hemorrhage (microhemorrhage) and calcification by exaggerating susceptibility signal intensity, which is more sensitive than T2 gradient echo.
