| pubmed-article:963852 | pubmed:abstractText | The reliability of myocardial perfusion scintigrams with thallium-201 (201Tl) for detecting areas of hypoperfusion was assessed in 16 closed-chest dogs. Variable areas of ischemia were produced either by occluding or stenosing the left anterior descending coronary artery. Cardiac scintigrams taken in four projections were compared with regional myocardial perfusion maps. Segmental concentrations and segmental perfusions were quantitated by counting the emissions from 201Tl and the microspheres in each of 96 segments of the left ventricle. In addition, studies with a phantom were performed. The results indicate: 1) The emissions from 201Tl and from microspheres correlated well in ischemic segments (r = 0.93 +/- SE 0.02). 2) Seven of twelve ischemic hearts had definitely abnormal scintigrams and in each of these the hypoperfused zone was greater than 4.9 grams and perfusion was decreased by more than 45%. 3) In the phantom, abnormal scintigrams could be detected in the presence of lesser deficits than in the dogs. The limitation of the thallium perfusion scintigrams will be the inconsistent detection of small perfusion deficits. | lld:pubmed |
