Cranial tissues: normal MR appearance after intravenous injection of Gd-DTPA

摘要: The effect of intravenously administered gadolinium DTPA on signal intensity normal intracranial structures was analyzed in 25 patients. Magnetic resonance (MR) image enhancement with Gd-DTPA differs from computed tomography aqueous iodinated contrast media. Marked owing to observed the pituitary gland, infundibulum, cavernous sinus, cranial nerves, choroid plexus, and nasal mucosa. Enhancement not visible routinely falx cerebri, tentorium cerebelli, dura, or rapidly flowing blood. efficacy any individual MR study may be assessed by observing stalk,
