Acetazolamide vasoreactivity evaluated by transcranial harmonic perfusion imaging: relationship withith transcranial Doppler (TCD) and with dynamic CT (DCT), during acetazolamide (ACZ) vasoreactivity tests.... The subjects were 12 neurological patients. Time-averaged maximum velocity (TAVMX) in the middle (MCA) and posterior cerebral arteries was measured by TCD. Time-intensity (-density) curves o

Functional brain imaging of optical topographyin spectroscopy. ETG-100 measures the oxy hemoglobin, deoxy hemoglobin and total hemoglobin volume changes in cerebral cortex..This optical topography system has various features, i.e., displaying the hemoglobin volume change in 2 dimensional images, non-invasiveness, compactness, low cost and less

Significant shrinkage of extracellular space during global cerebral ischemia: differences in gray anin ischemic changes of ECS in gray and white matter during global ischemia in cats (n = 8). Diffusion capacity of tetramethylammonium ion (TMA., 74.1Da) was evaluated by measuring extracellular TMA. concentration applied via microdialysis. In both gray and white matter, TMA. concentration significan

NTP and PCr responses to hypoxia by hypothermic and normothermic respiring, superfused, neonatal ratar mechanisms are appropriate. Anticipating future studies of hypothermia and hypoxia/ischemia, we investigated the extent to which our ex vivo, NMR-based, superfused brain slice model might be helpful. (Slices are ≈350 μm thick, with 18 slices per 8 mm NMR tube.) .P NMR spectroscopic measurements w

Concept and pathogenesis of “hypoxic-ischemic encephalopathy”long course of the medullary artery produces the blood pressure drop in the deep white matter according to Hagen-Poiseuille’s low, and according to that the smaller the diamter ratio, the larger the branching-loss coefficient (energy-loss coefficient), smaller diameter ratio of the pallidal perforat

Hydrostatic brain edema: basic mechanisms and clinical aspectain edema remains controversial. External decompression may have adverse effects on severe brain edema and swelling. In this regards, control of driving force for the formation of brain edema could be the treatment of choice as an initial step. In addition, recent reports provided by MR imaging indi

Estimating blood-brain barrier opening in a rat model of hemorrhagic transformation with Patlak plotas rather good, although no match for .C-sucrose-QAR. This study shows that quantitative ΔT.-MRI estimates of regional blood-brain transfer constants of Gd-DTPA and water distribution are possible when Patlak plots are employed to process the data. This approach may be useful for tracking the time-c

Recent development ofMR imaging technique for the investigation of brain functioncal setting, the concept of in-line evaluation technique is employed, which means real-time data processing. As soon as scanning is terminated, the processed images can be obtained to be used immediately for diagnoses.
