Clinical feasibility of 1-min ultrafast brain MRI compared with routine brain MRI using synthetic MRI: a single center pilot study.

Although the overall image quality and anatomical delineation of the 1-min ultrafast MRI were inferior to those of the routine brain MRI protocol, the ultrafast protocol showed at least sufficient image quality. Therefore, this protocol may be an option in specific clinical situations involving non-cooperative, restless, or pediatric patients, or patients with time-critical disease such as stroke. Further study is required to validate our findings.
