The sensitivity of rCBF SPECT increased from 62% to 77% after acetazolamide provocation in stroke patients. In patients with a reversible neurological deficit, the sensitivity under resting conditions was 50% which increased to 71%, while in cases with a permanent deficit it increased from 75% to 83%. In the evaluation of the cerebrovascular reserve capacity the results of rCBF SPECT and TCD coincided in 91% of the hemispheres. The correlation was statistically significant. %B NUKLEARMEDIZIN-NUCLEAR MEDICINE %V 33 %P 239 - 243 %8 1994 %@ 0029-5566 %G eng %N 6 %! NUKLEARMED-NUCL MED
