Conventional 1.5T and 3.0T cardiac MRI(CMRI)had been widely used.The ultrahigh field MR behaved better in image resolution and signal-to-noise ratio.The domestic 5.0T whole-body ultrahigh field MRI had better balance between the field strength and quality in CMRI,which was expected to improve imaging quality and efficiency.The status challenges and future of 5.0T CMRI were reviewed in this paper.
