fast spin-echo (FSE)

a magnetic resonance imaging technique that uses multiple spin-echoes to reduce imaging times in comparison to spin-echo imaging. See also spin-echo.

These techniques can be used to decrease imaging time in both fast spin-echo and gradient-echo imaging, and are best thought of in the framework of those sequences rather than in isolation.
For T2-weighted fast spin-echo sequences, the following parameters were applied: repetition time/echo time = 5100/102 ms, turbo factor = 19, matrix = 512 x 408, field of view = 18 cm, slice thickness = 5 mm, and scan time = 2 minutes.

To completely evaluate the ankle, the imaging protocol usually consists of coronal and axial T2-weighted fast spin-echo images with fat suppression, axial proton density-weighted fast spin-echo images, sagittal fast spin-echo inversion recovery images, and sagittal and axial T1-weighted spin-echo images (6).

Routine 2-dimensional imaging of the knee includes fast spin-echo (FSE) T2- and/or FSE proton density (PD)-weighted coronal and sagittal sequences, with or without fat suppression.
Fast spin-echo techniques can add resolution to MRIs, and fat-suppression techniques distinguish adipose tissue from pathology.
Just as in the and fractures can be difficult to appreciate with routine spine imaging sequences employing fast spin-echo T2-weighted images, particularly if fat-suppressed or STIR techniques are not employed.
