Ein halbautomatisches Programm für die Auswertung von Radioventrikulogrammen in der Erstpassagetechnik

Abstract

Evaluation depends mostly on the demonstration of regional function (muscle movement, regional contraction volume, trend scintigram). A special technique permits the demonstration of insufficiency of the A-V valves and its approximate measurement. Comparison with single plane angiography showed good or excellent agreement concerning the ejection fraction (r = 0.86 for patients in sinus rhythm, 0.92 for patients without valvular disease). Inter observer error is very small (r = 0.99). These studies can be evaluated separately for the right and left ventricles (in an RAO 30 degrees projection).

On the Prognostic Potential of the Sequential 123-I-HDA-Tomoscintigram After the First MI

“…But, this initial cool-warm behaviour itself is by no means a predictor for the later outcome: the EF.does not increase with higher d-type scores, neither does the end-systolic volume shrink. Only a slightly better reduction of the end-diastolic volume occurs with an initially more extensive ischaemic lesion (Table 1, [10][11][12][13][14]. Comparing those Mis with a high ischaemic score (i.e.…”
