Purpose
Background: Correct and reproducible evaluation of left (LV) and right (RV) ventricular functional parameters represents the basis for decision making in cardiac and pulmonary diseases. Thanks to high temporal, spatial and contrast resolution 2D-bSSFP magnetic resonance sequence guarantees the best results in terms of accuracy for LV and RV volume assessment and it is nowadays regarded as the in vivo gold standard for this aim. Recently, thanks to the possibility of acquiring non invasive images of coronary artery tree, numerous studies explored the role of...
Methods and Materials
we included 79 patients who underwent Cardiac CT (Sensation 64, Siemens) and Cardiac MR (Achieva 1.5T, Philips) to exclude coronary artery disease (CAD). We used direct short axis (SAX) multiphasic reconstructions for CT and 2D cine b-SSFP SAX sequences for MR. Datasets were evaluated with a dedicated software (Argus, version Va60C, Siemens). Results were compared with paired Student’s t Test, Pearson’s r, and Bland-Altman analysis.
Results
excellent agreement was observed between CT and MR. No significant differences were observed between CT and MR in the evaluation of LV and RV functional parameters: LV EF (52% ± 14% for CT vs 52% ± 14% for MR; r=0.73; p>0.05); RV EF (47% ± 12% for CT vs 47% ± 12% for MR; r=0.74; p>0.05); LV EDV ( 74ml/m² ± 21ml/m² for CT vs 76 ml/m² ± 25 ml/m² for MR; r=0.59; p>0.05); RV EDV ( 84ml/m² ± 25ml/m² for CT vs 80ml/m² ±...
Conclusion
MR and CT show no significant difference for LV and RV volume evaluation. Cardiac CT provides accurate and reproducible LV and RV volume parameters as the actual gold standard.
