Comparaison des méthodes 2D et 3D dans l’évaluation des fonctions ventriculaires globales en scanner multi-détecteurs

Abstract : PURPOSE: To compare two methods of post processing cardiac CT data to measure global ventricular function. Materials and methods. Retrospective study where three readers measured the end-diastolic volume (EDV), end-systolic volume (ESV) and ejection fraction (EF) of the right (n=22) and left (n=44) ventricles, using a 2D method (extrapolated volumetric method, EVM) and a 3D method (direct volumetric method, DVM) after cardiac CT with retrospective ECG gating. Inter- and intraobserver agreement were calculated based on the intraclass correlation coefficient (ICC) with 95% confidence interval (CI95%), and results obtained with each method were compared using the student t test for paired samples. RESULTS: Inter- and intraobserver reproducibility were very good for both methods, with ICC ranging between 0.694 and 0.992, without significant difference. For the left ventricle, EDV, ESV and EF were 16653 ml, 8351 ml and 5415% for DVM et de 20361 ml, 11558 ml and 4613% for EVM respectively. Right ventricular values were 15247 ml, 7534 ml, 5013% and 17253 ml, 9940 ml, 439% (p<0,0001). CONCLUSION: The very good inter- and intraobserver reproducibility for both methods validate their use in clinical practice. Volume measurements with DVM are always inferior to volumes with EDM, with inverse relationship for EF measurements.
