All two-dimensional (2D) and three-dimensional (3D) MRCP imaging was obtained with 2D thick-slab single-shot turbo spin-echo with a relaxation enhancement sequence and with 3D T2-weighted respiratory-triggered
fast spin-echo sequence using a navigator technique.
Fast spin-echo triple-echo dixon (fTED) technique for efficient T2-weighted water and fat imaging.
Static-fluid MR urograms technique was deployed, obtained with single-shot
fast spin-echo techniques in 1-2 seconds.
T2WI images were scanned using a
fast spin-echo sequence by multiple slices (15 slices; 1.8 mm slice thickness and 1 mm interslice distance).

MRI of the brain was performed using spin-echo and
fast spin-echo pulse sequences.
From a strictly technical point of view, even if some authors [20] still claimed that noncontrast MR lymphangiography using very heavily T2-weighted
Fast Spin-Echo (FSE) sequences is a unique, non invasive, imaging modality for the diagnosis of lymphedema, the majority of authors perform MRL using both heavily T2-weighted and heavily T1-weighted postcontrast sequences.
MR cisternography is performed using a three-dimensional thin-section heavily T2-weighted image
fast spin-echo sequence or steady-state gradient-echo sequence (Constructive Interference in Steady State or Fast Imaging Employing Steady State Acquisition).
[25], who reported that all 5 of their cases showed increased T2-weighted (
fast spin-echo) signal in subchondral bone underlying the cartilage injury, indicating oedema.
Total imaging time was 25 minutes and images obtained were: Sagittal and Axial T2-weighted
fast spin-echo images; Axial T1-weighted spin-echo images; Axial T2-weighted spin-echo images through any lesion images with the addition of frequency-selective fat suppression; and Coronal T2-weighted
fast spin-echo images.
Size of the artifacts can be reduced by optimizing the MR imaging parameters such as change in pulse sequence from gradient-echo (GRE) to
fast spin-echo (FSE) pulse sequence.
