[Measurement of subarachnoid space with a short TR gradient echo method; myelo MRI].

: The cerebro-spinal fluid in the subarachnoid space is delineated clearly with gradient field echo technique (TR = 60 ms, TE = 20 ms, flip angle = 20 degrees). Average area, width, depth, and curvature of the subarachnoid space in the cervical region were obtained in ten young normal subjects.
