MR imaging of hemorrhagic brain lesions: a comparison of dual-echo gradient-and spin-echo and fast 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.
Axial slices were performed using single-shot fast spin-echo
(SSFSE) sequences; parameters: 90 TE.
Diffusion-weighted (DW) MRI scans were carried out on a 3T scanner using a radial fast spin-echo
Diffusion-weighted (DW) MRI scans were carried out on a 3-T scanner using a radial fast spin-echo
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).
5) High-resolution, fast spin-echo
T2-weighted MRI of the temporal bone is helpful in identifying cochlear soft-tissue abnormalities and residual cochlear patency.
Of 26 parous women with unexplained pelvic pain, 20 (77%) demonstrated levator ani defects when subjected to T2-weighted, fast spin-echo
and MRI in the axial and sagittal planes, he reported at the annual meeting of the Society of Gynecologic Surgeons.
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.
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.
