Summary

Acute myocardial infarctions were produced by ligature of the left frontal descending coronary artery in 9 dogs. The possibility of scintigraphic imaging with 99mTc-DMSA 4 hrs after intravenous administration was studied. The infarctions were 4, 24 and 48 hrs old. The in vivo scan was positive in only one dog with a 4-hr old infarction. The in vivo scans were confirmed by the analysis of the radioactivity in tissue samples. The accumulation of the radiopharmaceutical increased slightly in 48-hr old lesions; however, this increase was not sufficient for a positive scintigraphic finding. Thus, we do not recommend 99mTc-DMSA for clinical use in acute lesions.

Zusammenfassung

Akute Myokardinfarkte wurden operativ durch Unterbindung der linken frontalen absteigenden Koronararterie bei 9 Hunden hervorgerufen. Die Möglichkeit einer szintigraphischen Darstellung mit 99mTc-DMSA 4 Std. nach intravenöser Verabreichung wurde untersucht. Die Infarkte waren 4, 24 und 48 Std. alt. Lediglich bei einem Hund mit einem 4 Std. alten Infarkt war das Szintigramm in vivo positiv. Diese Szintigramme in vivo wurden durch eine Analyse der Radioaktivität in Gewebsproben be stätigt. Die Anwendung des Radiopharmazeutikums nahm geringfügig bei 48 Std. alten Läsionen zu, dieser Anstieg war jedoch unzureichend für einen positiven szintigraphischen Befund. Wir empfehlen daher 99mTcDMSA nicht zur klinischen Anwendung bei frischen Läsionen.
