FIG 5. Images obtained at 1.5 T (imaging time, 3 minutes) (A) and 0.35 T (imaging time, 11 minutes) (B) provided comparable anatomic information.
A, The imaging parameters at 1.5 T were as follows: field of view, 15 cm; section thickness, 1 mm; 5000/250/1 (TR/TE/excitations); one shot; echo train length, 148; matrix, 256 x 256 x 30, which zero-filled to 512 x 512 x 60; echo spacing, 12.5 milliseconds; and imaging time, 2 minutes 45 seconds.
B, The imaging parameters for 0.35 T were as follows: field of view, 15 cm; section thickness, 1 mm; 4000/240/2; two shots, echo train length, 76; matrix, 256 x 256 x 40, which zero-filled to 512 x 512 x 80; and imaging time, 10 minutes 44 seconds.
