What this trial studies
Cardiac MRI is the reference standard for measuring left ventricular ejection fraction, but conventional cine sequences require multiple breath-holds that can be difficult for elderly or dyspneic patients. This project uses an accelerated cine-CMR sequence combined with deep learning-based image reconstruction to shorten acquisition time and reduce breath-hold requirements. Adults referred for CMR for left ventricular hypertrophy will undergo the accelerated imaging and results will be compared with standard cine techniques for LVEF, ventricular volumes, and image quality. The aim is to determine whether accelerated, DL-reconstructed images maintain diagnostic accuracy while improving patient comfort and scan efficiency.
Who should consider this trial
Good fit: Ideal participants are adults (18+) referred for cardiac MRI to evaluate or follow left ventricular hypertrophy who can give informed consent and meet MRI safety requirements.
Not a fit: Patients with arrhythmias, severe obesity preventing scanner entry, inability to hold breath for at least 10 seconds, claustrophobia, pregnancy, gadolinium allergy, or other MRI contraindications are unlikely to benefit or may be excluded.
Why it matters
Potential benefit: If successful, patients could have shorter, more comfortable MRI exams that still provide accurate ejection fraction measurements, which would particularly help elderly or breathless patients.
How similar studies have performed: Prior studies of accelerated cine MRI with deep-learning reconstructions have shown promising results for preserving image quality and LVEF accuracy, though broader clinical validation is still ongoing.
