Abstract
To evaluate the usefulness of brain SPECT as a tool with diagnostic and prognostic values m patients with acute cerebral infarction, twenty-four patients who were diagnosed as embolic(n=12) or thrombotic(n7-12) infarction by clinical manifestation and brain CT or MRI were selected. Both 99mTc-HMPAO & 99mTc-DTPA Brain SPECT were performed for each patients within 1 week after the attack Asymmetric index(Al) in both hemispheres was calculated as 200(l(right-left)l/(right+left)). Activities of daily livmg(ADL) was scored by Barthel Index on the admission day and the 21st day after the attack. The relationshiop between ADL index and Al of two types of brain SPECT was analysed by calculating correlation coefficient. 1.In embolic infarction, the Al of 99mTc-DTPA SPECT was markedly higher than that of 99mTc-HMPAO spect, but there was no difference in thrombotic type. 2. The AI of 99m'Tc-DTPA SPECT in embohc infarction was sigiuficantly higher than that m thrombotic type(p valu=.001), but the Al of 99mTc-HMPAO SPECT was similar in both types of infarction. 3.The correlation coefficient Al of 99mTc-DTPA Brain SPECT and ADL m the 21st day after stroke was statistically significated. These results suggested that the 99mTc-DTPA brain SPECT should be useful not only for the differemtial diagnosis between thrombotic and embolic infarctions but also for the prediction of prognosis in patients with ischemic stroke.
