[Results of 201thallium myocardial scanning in coronary heart disease (author's transl)].
Quantifiable 201Tl scanning of the myocardium was performed in 23 patients with coronary heart disease and 10 without heart disease. Taking into consideration normal relative minimal storage of 201Tl in different regions of the myocardium (five projections), decreased 201Tl uptake in underperfused myocardium (acute myocardial infarction, coronary artery stenoses with hypo-, dys-, and akinesia) was recognizable according to extent and localisation (iso-impulse rate scan). The lowest relative 201Tl storage was found in dyskinesia or akinesia (37.6-54.1%) in the region of the anterior wall, as well as in acute myocardial infarction (50%). In the period after myocardial infarction persistence and normalisation of underperfusion could both be demonstrated. 201Tl scan as a non-invasive test is an appropriate means for demonstrating relative regional perfusion in the myocardium, with myocardial capacity for active uptake of potassium-like thallium being determined at the same time.
