Overview

The assessment of the cerebrovascular reserve capacity (CVRC) of the brain in patients with occlusion of the internal carotid artery is one of the procedures that is included in the planning of revascularization bypass surgery. The authors present an examination method of which they have experience – stress brain single photon emission computed tomography (SPECT) with carbon dioxide. Basic information regarding two nuclear medicine methods, brain SPECT using the ¹³³Xe and positron emission tomography using the ¹⁵O, are also presented. The latter method is considered the gold standard in CVRC examination. Other nonradionuclide imaging methods, transcranial Doppler sonography, perfusion computed tomography of the brain, and functional magnetic resonance imaging, are also mentioned.

Key words:
cerebrovascular reserve capacity – brain SPECT – hypercapnia – acetazolamide
