Feasibility evaluation demonstrates comparable liver MRI quality between free-breathing radial scans and breath-holding, suggesting an effective alternative for patients with poor breath-holding.
The gadoxetic acid-enhanced hepatobiliary phase imaging is an effective sequence for detecting hepatic lesions; however, degraded image quality is often observed due to poor breath holding. Free-breathing sequence using radial stack-of-stars acquisition (3D VANE) has been introduced and can provide diagnosable image quality. Recently, Compressed SENSE (CS), that is one of the acceleration techniques, has been applicable in 3D VANE. In this study, we evaluated the feasibility of 3D VANE with CS in hepatobiliary phase imaging. Our results showed that 3D VANE with CS at section thickness of 2 mm had almost comparable image quality as conventional breath-holding cartesian sampling.
