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.
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).

From a strictly technical point of view, even if some authors  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).
, 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
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.
