Zusammenfassung
Ziel: Vergleichende Bestimmung linksventrikulärer (LV) globaler und regionaler Funktionsparameter, Volumina und Wandstärkenänderungen sowie segmentale Analyse der Wandbewegung (WB) durch Dual-Source-CT (DSCT) und MRT. Methoden und Materialen: 30 Patienten mit bekannter oder vermuteter KHK, nichtobstruktiver HCM, DCM, ARVCM, Fallot-Tetralogie, kardialer Sarkoidose bzw. kardialen Metastasen unterzogen sich einer DSCT und MRT. Beide Untersuchungen wurden hinsichtlich endsystolischer (ESV) und -diastolischer (EDV) LV-Volumina, Schlagvolumina (SV), Ejektionsfraktion (EF) und myokardialer Masse (MM), der linksventrikulären Wanddickenzunahme sowie segmentaler Wandbewegung (Segmentmodell der AHA) statistisch ausgewertet. Ergebnisse: Die mittels DSCT bestimmten enddiastolischen (r = 0,96) und -systolischen Volumina (r = 0,98) korrelierten gut mit den MRT-Messungen. Die LV-EF (r = 0,97), SV (r = 0,83) und MM (r = 0,95) zeigten eine sehr gute Korrelation. Die Bland-Altman-Analyse zeigte eine geringe Unterschätzung der LV-EF (–1,1 ± 7,8 ml), EDV (–0.3 ± 18.2 ml) sowie Überschätzung von ESV (1.1 ± 7.8 ml) und MM (12.8 ± 14.4 g). Der systolische Rekonstruktionszeitpunkt wies eine gute Übereinstimmung (DSCT 32,2 ± 6,7 vs. MRT 35,6 ± 4,4 % RR-Intervall) auf. Die Wandstärke zeigte für alle LV Segmente eine gute Korrelation beider Modalitäten (mittlere Diff. 0,42 ± 1 mm). Störungen der WB wurden mit beiden Modalitäten in 413 Segmenten (89 %) übereinstimmend beurteilt, wobei die DSCT den Grad der Bewegungseinschränkung geringgradig unterschätzte. Schlussfolgerung: Die DSCT mit optimierter zeitlicher Auflösung ermöglicht die Analyse der regionalen und globalen LV-Funktion und die segmentbasierte Quantifizierung der regionalen WB in sehr guter Korrelation zur MRT. Dabei unterschätzt die DSCT den Grad der myokardialen Bewegungseinschränkung.
Abstract
Purpose: To determine regional and global left ventricular (LV) functional parameters and to perform segmental wall thickness (SWT) and motion (WM) analysis of dual-source CT (DSCT) with optimized temporal resolution versus MRI. Materials and Methods: 30 patients with known or suspected CAD, non-obstructive HCM, DCM, ARVCM, Fallot Tetralogy, cardiac sarcoidosis and cardiac metastasis underwent DSCT and MRI. The DSCT and MR images were evaluated: end-systolic (ESV), end-diastolic LV (EDV) volumes, stroke volume (SV), ejection fraction (EF), and myocardial mass (MM) as well as LV wall thickening and segmental WM applying the AHA model were obtained and statistically analyzed. Results: The mean LV-EDV (r = 0.96) and ESV (r = 0.98) as well as LV-EF (r = 0.97), SV (r = 0.83), and MM (r = 0.95) correlated well. Bland Altman analysis revealed little systematic underestimation of LV-EF (–1.1 ± 7.8 %), EDV (–0.3 ± 18.2 ml), SV (–1.3 ± 16.7 ml) and little overestimation of ESV (1.1 ± 7.8 ml) and MM (12.8 ± 14.4 g) determined by DSCT. Systolic reconstruction time points correlated well (DSCT 32.2 ± 6.7 vs. MRI 35.6 ± 4.4 % RR-interval). The LV wall thickness obtained by DSCT and MRI showed close correlation in all segments (Ø diff 0.42 ± 1 mm). In 413 segments (89 %) WM abnormalities were equally rated, whereas DSCT tended to underestimate the degree of wall motion impairment. Conclusion: DSCT with optimized temporal resolution enables regional and global LV function analysis as well as segmental WM analysis in good correlation with MRI. However, the degree of WM impairment is slightly underestimated by DSCT.
