Imaging studies included sagittal SPAIR sequence (TR/TE, 2538 ms/70 ms; TI, 110 ms; echo train length, 19; FOV, 280 mm; matrix, 320x218; NEX, 1; acquisition time, 1:33 min; slice thickness/gap, 4 mm/0.4 mm) and T2 Dixon sequence (TR/TE, 2208 ms/10 ms; echo train length, 22; FOV, 283 mm; matrix, 380x262; NEX, 1; acquisition time, 2:20 min; slice thickness/gap, 4 mm/0.4 mm).
Imaging parameters which were held constant during the study for CSE, FSE, FLAIR in T1-weighted study (field of view, 100x100 mm; number of acquisitions, 1; slice thickness, 4 mm), FLAIR (inversion time, 400 ms; echo train length, 7) and FSE (echo train length, 12).
560ms, echo train length was 3, band width was approx.
4200, echo train length was 12, band width was 15.6, slice thickness, spacing, patient's position, mode of imaging and coil remained the same as that of T1 weighted images.
One may expect that the chosen sequence that performs better for lead blooming and tissue contrast would use perfect refocusing RF pulses, long echo train length (ETL), and short echo time (TE).
The results demonstrate that by lowering echo time or increasing echo train lengths in fast spin echo the tissue visualization surrounding the DBS contacts is better than that obtainable by gradient echo based imaging and it is possible to achieve a fairly small metallic artifact blooming from the DBS leads.
Initial solutions to the long acquisition times for 3-dimensional FSE imaging focused on obtaining more echoes per magnetization pulse (i.e., increasing the echo train length, ETL) and reducing the time between successive magnetization pulses (decreasing repetition time, TR).
The effective TE determines the echo train length (ETL) based on echo spacing (ESP).
Certain imaging parameters were held constant during the study for CSE, (field of view, 100A-100 mm; number of acquisition,1; slice thickness,4mm; percentage sampling, 100; pixel per mm resolution, 1.280), FLAIR(inversion time, 860 ms; echo train length, 5) and FSE (echo train length, 7).
