Abstract:
:Two patients with subacute cerebral infarction underwent benzodiazepine receptor imaging using I-123-iomazenil and cerebral perfusion imaging with Tc-99m HMPAO and Tc-99m ECD. Iomazenil early images resembled HMPAO images, which demonstrated increased uptake in a part of the infarcted site. Iomazenil delayed images and ECD images showed reduced accumulation in the same area. Crossed cerebellar diaschisis was observed in HMPAO, ECD, and iomazenil early images, but it was not remarkable in iomazenil delayed images. These cases suggest that sequential iomazenil images visualized increased uptake with relatively impaired viability in the infarcted site and hypoperfusion with preserved viability in the contralateral cerebellar hemisphere, which could not be recognized without using both HMPAO and ECD in the subacute phase of cerebral infarction.

杂志文章abstract::Cerebral vascular lesions are integral to the diagnosis of vascular parkinsonism (VP). The VP, also referred to as lower body parkinsonism, is frequently caused by subcortical white matter lesions, but lesions at any levels of the nigro-striato-thalamo-cortical pathway can also cause VP, thus giving rise to various sy...
