3D Whole-Heart Coronary Magnetic Resonance Angiography at 0.55T: A Clinical Feasibility Study in Patients with Cardiovascular Disease

Key Points

Coronary artery disease was successfully detected using 3D coronary MRI at 0.55T, demonstrating feasibility.
Mean image quality scores for the coronary vessels were largely satisfactory, with RCA achieving a score of 3.5.
Seventeen patients with suspected cardiovascular disease underwent scanning, averaging about 8 minutes per scan.
This work may enable broader use of low-field MRI for coronary assessments, challenging traditional high-field approaches.

Abstract

Motivation: Low-field (<1T) MRI is gaining interest and may provide a solution to traditional high purchase and running costs. Goal(s): To utilise 3D coronary MRA (CMRA) at 0.55T to assess coronary anatomy in patients with cardiovascular disease (CVD). Approach: Seventeen patients with suspected CVD were scanned using 3D CMRA at 0.55T. Each coronary artery was assessed for image quality and presence of coronary artery disease. Results: The mean image quality score for each vessel was, LAD: 3.1 (SD=0.8); LCx: 2.8 (SD=0.8); RCA: 3.5 (SD=0.5). Average scan time was ~8 minutes. Coronary artery disease was successfully detected. Impact: This work demonstrates the feasibility of coronary artery assessment using 3D CMRA at 0.55T in patients with cardiovascular disease.
