Multiple scattered microbleeds on gradient-echo magnetic resonance imaging may be found as a consequence of cerebral microangiopathy due to hypertension, amyloid angiopathy, or hemorrhagic conversion of cardiac emboli or artery to artery embolization.¹ Amyloid deposition in the setting of Alzheimer disease or intracerebral hemorrhage can be studied in humans by performing carbon 11 ([¹¹C])–labeled Pittsburgh Compound B positron emission tomography. This positron emission tomography tracer has a high affinity for vascular as well as plaque β-amyloid and is increasingly being used in the evaluation of cognitive disturbance and stroke.²

A 60-year-old woman was admitted with acute onset of left-sided weakness and a National Institutes of Health Stroke Scale score of 4.
