Abstract

OBJECTIVE. The objective of this study was to evaluate the routine use of gradient-refocused echo MRI sequences in the detection of cortical cerebral microbleeding suggestive of cerebral amyloid angiopathy in elderly patients (> 70 years old). CONCLUSION. The addition of gradient-refocused echo sequences to routine brain MRI resulted in the identification of cerebral amyloid angiopathy-related microbleeding in 15.5% of elderly patients. In most (86.7%) of these patients with positive findings, cerebral amyloid angiopathy was not suspected clinically, and 46.7% of these patients were undergoing anticoagulant or aspirin therapy, placing them at an increased risk of recurrent intracranial hemorrhage and catastrophic stroke.
