[Diagnostic use of myocardial scintiscanning with thallium-201 in myocardial infarct].
Myocardial scintigraphy shows to have diagnostic ability after latest proposal to use Thallium-201. Thus we verified its iconographic effectiveness in 10 normal subjects and 25 patients with myocardial infarction variously localized. In both groups we obtained adequate and expressive results: the former showed omogeneous images and continuous outlines, whereas the latter showed "cold areas" in agreement with the localization provided by electrocardiography. The further utilization of myocardial imaging with Thallium-201 in 2 patients with prior infarction, in whom present ecg is equivocal, provided scintigraphic evidence of prior necrotic lesion. This emphasizes diagnostic sensitivity of myocardial scintigraphy with Thallium-201 encouraging its use in those patients in whom electrocardiography is not able to give its usual diagnostic contribution.
