Fig. 4From: Idiopathic basal ganglia calcification associated with cerebral micro-infarcts: a case reportSingle-photon emission computed tomography (SPECT). Quantitative CBF assessment with SPECT showed a mild decrease in resting CBF and a severe decrease in CVR over almost all the cerebral area in an acetazolamide-tolerance test. Images are shown at the level of (a) the centrum semiovale and (b) the basal ganglia. ACZ; acetazolamide, CVR; cerebrovascular reactivityBack to article page
