T1-weighted FLAIR MR Imaging for the Evaluation of Enhancing Brain Tumors: Comparison with Spin Echo Imaging

MR T1-weighted images (T1WI) are mainly used to the anatomical details and pathological abnormalities of the intracranial lesions. Spin-echo (SE) technique has been the most commonly used pulse sequence for T1WI (1). T1-weighted fluid-attenuated inversion recovery (T1FLAIR) is a relatively new pulse sequence and it provides higher tissue contrast between the gray and white matter (WM) of the brain than T1-weighted INTRODUCTION �Received; February 1, 2014�Revised; May 17, 2014 �Accepted; May 19, 2014 Corresponding author : Dae Seob Choi, M.D. Department of Radiology, Gyeongsang National University Hospital, Gyeongsang National University School of Medicine, 90 Chilam-dong, Jinju 660-702, Korea.
