Critical evaluation of the hemispheric perfusion brain scanning using Tc99m labeled human albumin microspheres in cerebral ischemic disorders. Preliminary report.
Twentytwo patients, 11 with Completed Stroke and 11 with Transitory Ischemic Attacks, were submitted to the Perfusional Brain Scanning (PBS). In all cases the PBS demonstred a pathologic pattern. The test explored the conditions of the arteriolar tree and acquainted us with the degree of the ischemic damage and the functional value of the interhemispheric arterial collateral circle. Further informations on the morphology, site and extension of the lesion were obtained. The pathophysiologic aspects of the procedure are discussed and its safety assessed.
