The primary objective of this study is to identify advantages or disadvantages of of Radiology, Larissa, Greece the T1-weighted fluid attenuated inversion recovery (FLAIR) sequence with BLADE technique (T1W-FLAIR BLADE), with and without parallel imaging when compared with T1 Turbo Spin Echo (T1 TSE) sequence 3Department of Medical Imaging, IASO Thessalias Hospital, Larissa, Greece when performing MRI examination of the lumbar spine in a sagittal view. 4Long School of Medicine, University Methods: L-spine examinations with T1W-FLAIR BLADE (with and without parallel imaging) and T1 TSE of Texas Health at San Antonio, San were acquired on 44 patients using a 1.5T scanner. These sequences were assessed by two radiologists Antonio, TX, USA a) quantitatively by comparing the signal-to-noise ratio (SNR), contrast-to-noise ratio (CNR) and relative contrast (ReCon) measurements and b) qualitatively based on different features of the images such as 5 Department of Radiology, University cerebrospinal fluid (CSF) nulling.
