[Dynamic MR imaging of the pituitary gland by the fast spin echo (RARE) sequence].
The Fast Spin Echo (RARE: Rapid Acquisition with Relaxation enhancement) sequence for the dynamic MRI of the pituitary gland was performed in 18 patients suspected of the intracranial lesions. The SNR of the plain image of 5 pituitary glands was measured on the FSE 400 and 200/17/8/2 (TR/effective TE/echo train length/excitation) and the spin echo 100/11/2 (TR/TE/excitation) sequence. The FSE (TR = 400) provided the highest SNR than others, The FSE sequence was able to acquire increased spatial resolution and reduced acquisition time, and was the significant sequence for the dynamic MRI of the pituitary gland.
