Sonic DL Cardiac Cine MRI at 3T: Comparison with Conventional Segmented Cine MRI

Motivation: This study aimed to explore the feasibility and accuracy of Sonic DL cardiac magnetic resonance cine technology. Goal(s): We aimed to assess the performance of Sonic DL cine MRI at 3T for left ventricular (LV) volume and mass measurement, especially patients with arrhythmia and/or difficulty in breath-holding. Approach: 48 patients were consecutively enrolled. EDV, ESV, SV, EF, and LV mass were measured. The agreement and correlation of the parameters were assessed. Image quality was evaluated and structure visibility rating. Results: Good agreements and correlations were found between the techniques for measuring left ventricular function. Impact: Sonic DL cardiac cine MRI allowed the assessment of LV volume with high accuracy and showed a significantly better image quality.
