MR assessment of normal brain development in neonates and infants: comparative study of T1- and diffusion-weighted images.

abstract：:Although tuberculosis is an uncommon cause of spinal arachnoiditis, it needs to be differentiated from other causes of arachnoiditis because it is a treatable disease. Myelography, which is the imaging modality of choice for the chronic adhesive stage of tuberculous arachnoiditis, usually reveals irregularity of the t...
