[Tl-201-imaging as a follow-up method after left ventricular aneurysmectomy (author's transl)].
Thallium myocardial scanning was performed in 30 patients after aneurysm resection of left ventricle. The aim of the study was to try an assertion about the completeness of adaptation of the marginal zones of aneurysm and about the postoperative reduction of left ventricular size. After standardization of size and distance of pictures we suggested quantification of dimensions of left ventricle by counting picture-points using a computer matrix. For that purpose left ventricle had to be deliminated exceptional distinctly from the background. That intention was realized by an interpolating background subtraction. Postoperatively an evident reduction of heart size, especially of ventricle cavity could be proved. Thallium myocardial scanning therefore seems to be suitable for postoperative supervision after aneurysm resection too.
