Pathophysiological correlates of thallium-201 myocardial uptake in experimental infarction
Cardiovasc Res.
1977 Mar.
Abstract
The pathophysiological correlates of thallium-201 (201TI) myocardial uptake were studied in a 24-hour-old closed-chest canine infarct model. Reduction in regional 201Tl uptake correlated well with the magnitude of tissue creatine phosphokinase depletion and microsphere estimates of transmural blood flow. In low flow endocardial regions 201Tl occasionally under-estimated the magnitude of flow reduction. Even slight reductions of 201Tl uptake (less than 0.86 of normal) were associated with histopathological and histochemical evidence of necrosis.
