To evaluate cine Cardiac Magnetic Resonance – Steady State Free Precession (CMR-SSFP) imaging quality and diagnostic accuracy in the assessment of cardiac valve morphology.
Evaluation of cardiac valve morphology has not been considered an indication for cardiac MRI due to suboptimal imaging quality; few studies have examined this objectively. MRI techniques utilizing CMR-SSFP may have overcome this limitation. Evaluation of CMR-SSFP diagnostic imaging quality in the assessment of valve morphology has not been performed for pediatric/congenital heart disease. Comparison of CMR-SSFP diagnostic accuracy of aortic valve morphology to echocardiography has not been previously performed.
Diagnostic clarity score
No blurring, excellent diagnostic data
Mild blurring, very good diagnostic data
Moderate blurring, diagnosis possible
Severe blurring, diagnosis uncertain
Non-diagnostic, diagnosis not possible
Proportion of valve components with a high-quality diagnostic imaging (Diagnostic clarity scores 1 or 2)
In the majority of cases CMR-SSFP produces high diagnostic quality imaging of cardiac valve morphology in congenital/pediatric cardiac MRI. The valve components with the highest diagnostic clarity score are tricuspid and mitral valve annuli, leaflets and papillary muscles and aortic valve annuli and leaflets. CMR-SSFP however produced high clarity images of chordae in only a minority of cases. Aortic valve morphology can be diagnosed with a high degree of reliability.
