Susceptibility weighted imaging: Clinical applications and future directions

Figure 1 A 68-year-old man with cerebral amyloid angiopathy. A: Axial FLAIR image demonstrates periventricular confluent hyperintense regions; B: Axial T 1 weighted SE image shows high signal intensity subacute hemorrhage in the left occipital lobe; C and D: On SWI minIP images, hemorrhage is depicted as a hypointense signal intensity lesion and, in addition to the left occipital lobar hemorrhage, one can see multiple microhemorrhagic lesions in the cortical and subcortical white matter from cerebral amyloid angiopathy. SWI: Susceptibility weighted imaging; minIP: Minimum intensity projection algorithm; SE: Spin echo.
