We report 4 cases of calcified cerebral emboli and demonstrate the value of CT in the diagnosis and temporal evaluation of such emboli.

Cerebral Ischemia and Infarction From Atheroemboli <100 m in Size

Background and Purpose—To determine the importance of emboli not trapped by carotid angioplasty filtration devices, we examined fragments 100 m released with ex vivo angioplasty and asked if fragment composition and size correlated with brain injury. Methods—Human carotid plaques (21) were excised en bloc, and ex vivo carotid angioplasty was performed. Eight plaques were selected as either high...

Doppler Emboli in Acute Stroke 383 Middle Cerebral Artery Doppler Emboli Signals in 45 Patients With Ischemic Stroke

Background and Purpose Doppler ultrasound detection of emboli signals may assist in distinguishing erabolic from thrombotic stroke. Selected patient groups have a high incidence of such signals. We have examined consecutive stroke cases to identify the incidence of Doppler emboli in different etiologic subtypes of stroke. Methods Forty-five patients presenting with first-ever acute carotid terr...
