[Functional scintigraphy of radioactive cardiac blood pool: amplitude and phase analysis and conventional parameters of left-ventricular wall motion at rest].
Authors performed quantitative assessment of 13 global and regional, left ventricular wall motion parameters obtained from 52 radioactive blood pool cardiac scintigrams. Of these performed in 1986 examinations, authors selected 3 equipotent patients' groups (myocardial infarction, cardiac aneurysm, cardiomyopathy) thus the contractility disorders were located in inferior wall segments. 13 examinations of the same material, without contractility disorders were selected (standard). Using time-activity curve authors measured following global parameters: ejection fraction (EFg1), mean ejection rate (MER), peak ejection rate (PER), peak filling rate (PFR), time from the end-systole to peak filling rate (tPFR) and regional parameters such as: regional and local ejection fraction (EFr and EF1), time from the beginning of the cycle to the end-diastole (ED) and to the end-systole (ES), contractility (KURCZ), amplitude of contractions. (AMPL) and of phase (PHASE) as well as standardized variables of amplitude distribution (SDU). The most significant quantitative parameter was EFgl. Dyskinesis symptom was the most important for cardiac eneurysm diagnosis. Phase shift served a confirmation of aneurysm earlier diagnosed using a cinematic display.
