Images of CAA collected at 1.5 T. Left, conventional T2* (TE=20 ms), center, SWI processed magnitude image (TE=40 ms) and right, SWI phase image (TE=40 ms) Gradient recalled echo (GRE) imaging is the conventional way to detect hemorrhage in CAA , however SWI is a much more sensitive technique that can reveal many micro-hemorrhages that are ...
CAA is associated with brain hemorrhages, particularly microhemorrhages.The accumulation of amyloid beta peptide deposits in the blood vessel walls results in damage of the blood vessels and hindrance of normal blood flow, making blood vessels more prone to bleeding [10] Since CAA can be caused by the same amyloid protein that is associated with Alzheimer's dementia, brain bleeds [11] are more ...
Cerebral microhemorrhages is a smaller form of hemorrhagic parenchymal contusion and are typically found in white matter. Such microhemorrhages are difficult to be detected on CT scan, but easily detected on gradient echo and susceptibility weighted imaging on MRI scan as hypointense susceptibility blooming.

[7] [8] The incidence is much higher in the elderly, especially those who are 85 or older, who are 9.6 times more likely to have an intracerebral hemorrhage as compared to those of middle age. [8] It accounts for 20% of all cases of cerebrovascular disease in the United States, behind cerebral thrombosis (40%) and cerebral embolism (30%).
