JCMR 2020; 22:37. A comparison of cine CMR imaging at 0.55T and 1.5T (CME)

Purpose/ Objective

Clinical CMR is relatively inaccessible based on its cost and technical requirements. Lower field MRI systems could improve the accessibility of clinical CMR. The general assumption is that low field MRI offers low quality imaging, however new high-performance low-field MRI systems may offer good image quality for clinical application. Some advantages of lower magnetic field MRI include the scaling of T1 and T2 tissues parameters, improved field homogeneity, and reduced RF-induced heating. The optimization of low field MRI imaging methods, including the use of modern acquisition and reconstruction strategies, can enable high quality CMR imaging that provides equivalent diagnostic capabilities. Following this CME activity learners should be able to: 1. Describe how a high-performance low field MRI system performs for quantitative cine CMR imaging, compared to conventional methods. 2. Describe how protocol optimization can be performed to improve image quality using low field MRI.
