[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 significance (Z=-3.317, P=0.001). FSE-T2WI (R/L) and IDEAL FSE-T2WI (A/P) difference with statistical significance (Z=-4.600, P=0.000). FSE-T2WI (A/P) and IDEAL FSE-T2WI (A/P) difference with statistical significance (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.
