PERCUTANEOUS CEREBRAL ANGIOGRAPHY AND CEREBRAL ABSCESS

Archives of Neurology And Psychiatry, 1949
THE DIAGNOSIS and treatment of cerebral abscess have been subjects of discussion during recent years. Methods of exact focal diagnosis and detection of multiple abscesses have been lacking. The variety of the therapeutic methods is indicative of the unsatisfactory results obtained in the past.

Microembolism in Cerebral Angiography

Echocardiography, 1996
Using transcranial Doppler monitoring of middle cerebral artery blood flow velocity, a number of studies have detected transient high intensity embolic signals during cerebral angiography. These are particularly frequent during contrast injection, but also sometimes occur at the time of catheter and wire manipulations and following saline flushes ...
