High-resolution magnetic resonance imaging of basilar artery with iterative decomposition of water and fat with echo asymmetric and least-squares estimation (IDEAL):A feasibility study
摘要
Abstract
Objective:To evaluate the potential for high-resolution MR imaging using IDEAL FSE-T2WI compared with FSE-T2WI in the assessment of the basilar artery wall.Materials and Methods:High-resolution FSE (A/P), FSE (R/L) and IDEAL FSE (A/P) T2W images were acquired from basilar artery of 30 patients using 3.0 T MRI scanner. Imaging studies were evaluated for total image quality and graded using a 4-point Likert Scale (1, nondiagnostic; 4, outstanding).Results:The total scores for FSE-T2WI (A/P), FSE-T2WI (R/L) and IDEAL FSE-T2WI (A/P) images, respectively, were as follows: 81, 92 and 115. FSE-T2WI (A/P) and FSE-T2WI (R/L) difference with statistical signiifcance (Z=-3.317,P=0.001). FSE-T2WI (R/L) and IDEAL FSE-T2WI (A/P) difference with statistical signiifcance (Z=-4.600,P=0.000). FSE-T2WI (A/P) and IDEAL FSE-T2WI (A/P) difference with statistical signiifcance (Z=-4.540, P=0.000) . IDEAL FSE-T2WI images showed improved image quality compared to FSE-T2WI technique at 3.0 T.Conclusion:IDEAL FSE-T2WI is a feasible technique in the basilar artery for producing high-resolution T2-weighted imaging.关键词
