Effect of barrier opening on brain edema in human brain tumors.

摘要: Blood-brain barrier (BBB) opening was carried out in 10 patients with cerebral lesions, and the MRI findings were evaluated following opening. An intra-arterial injection of 10% glycerol (4 ml/kg, 1 ~ 2 ml/s) given as a hyperosmotic solution. T2weighted undertaken using TOSHIBA 22A at 30 minutes after BBB Barrier-opening performed times patients, including 5 cases glioblastoma multiforme, astrocytoma, case malignant lymphoma, contusion neurinoma. The high-intensity area (HIA) compared that without Three types changes HIA observed follows. Type 1: Expansion noted 4 lymphoma contusion. 2: Almost no change 3: A decrease astrocytoma multiforme.
