Having determined that edema and not vascular engorgement is the major factor leading to traumatic brain swelling, objective of this study was determine which type edema, cellular or vasogenic, responsible for increased tissue water in patients with focal lesions. Severely head injured (GCS 8 less) were transported imaging suites measurement apparent diffusion coefficient (ADC) using magnetic resonance technique. Cerebral blood flow by stable Xenon method also measured regions interest. Brain significantly hemisphere lesion. The increase associated reduced ADC signifying a predominant edema. contralateral near normal value. values interest above ischemic levels suggesting factors other than ischemia are cytotoxic swelling injury.
