Comparison of Image Quality between United Compressed Sensing with Radial Acquisition and Quick3D in Enhanced MRI of Liver
摘要
Abstract
Objective:To compare the image quality between united compressed sensing with radial acquisition(uCSR)and three-dimensional volume interpolation fast scrambling phase sequence(quick3D)in enhanced MRI of liver,and explore the value of uCSR in enhanced MRI of liver.Methods:Seventy-seven patients undergoing enhanced MRI of liver who had both uCSR and quick3D images were retrospectively collected from October 2022 to April 2023.Subjective image quality(o-verall image quality,liver edge sharpness,hepatic portal vein clarity,hepatic vein clarity and respiratory motion artifacts)and objective image quality including signal-to-noise ratio(SNR)and contrast-to-noise ratio(CNR)were compared between uCSR and quick3D sequences.Results:The subjective scores and CNR of uCSR were higher than those of quick3D in 77 pa-tients(all P＜0.05),and there was no significant difference in SNR between the two sequences(all P＞0.05).The uCSR showed lower overall image quality and liver edge sharpness,higher hepatic portal vein clarity than quick3 D in 47 patients with good breath holding,the differences were statistically signif-icant(all P＜0.05).There were no significant differences in other subjective scores,SNR and CNR between two groups(all P＞0.05).The subjective and objective image qualities of uCSR were higher than those of quick3D in 30 patients with poor breath holding(all P＜0.05).Conclusion:In enhanced MRI of liver,uCSR could provide equivalent image quality in pa-tients with good breath holding and better image quality in patients with poor breath holding compared with quick3D.关键词
