BACKGROUND AND PURPOSE Although gray matter (GM) and white matter (WM) have differing neurochemical responses to ischemia in animal models, it is unclear whether this translates into differing thresholds for infarction. We studied this issue in ischemic stroke patients using magnetic resonance (MR) techniques. METHODS MR studies were performed in patients(More)
BACKGROUND AND PURPOSE The classical mismatch pattern in the middle cerebral artery territory stroke on MR is defined by a central diffusion-weighted image core with surrounding mismatch tissue. Because of variable rates of tissue salvage, we hypothesized that this pattern may fragment over time and may be influenced by vessel patency, mismatch volume, and(More)
In order to prevent collision of the train movement or derailment, Automatic train protection (ATP) is needed as an important part of signaling system. Conventionally, a transponder or electro-magnet is used for communication between trackside device and onboard device of the ATP. ATP is not applied yet in Indonesia till now and all trains are operated by(More)
