      The possibilities of myocardial single-photon emission tomography (SPECT) in the evaluation of left ventricular postinfarction aneurysm are presented in this article. The radiopharmaceutical (RPH) 99mTc-MIBI with activity 7 MBk/kg was used for the myocardial SPECT. SPECT was performed at rest. Twenty five patients with postinfarction aneurysm were examined. Localization and the area of aneurysm, the level of RPH uptake and quantity of the viable myocardium were evaluated. The scintigraphic features of the aneurysm are homogeneously decreased perfusion, level of RPH uptake 5–12 % (average 8.2 ± 3.5 %) and left ventricular myocardium geometry alterations. The amount of viable myocardium varied from 40 to 58% (average 42.8 ± 7.7 %).

Key words: left ventricular aneurysm, myocardial single-photon emission tomography, myocardial viability, 99mTc-MIBI.
