Certain conditions -- including brain diseases (such as epilepsy), head injuries, drug and alcohol intoxication, and sleep deprivation -- can lead to symptoms similar to those of dissociative disorders, including amnesia (loss of memory).
Device Imaging. Many devices can be updated only by performing a full update of the operating system image on the device (a process referred to as device imaging in this document). The Operating System Deployment feature of Configuration Manager lets you deploy operating system images to devices.
Positron emission tomography. Positron emission tomography (PET) is a nuclear medicine functional imaging technique that is used to observe metabolic processes in the body. The system detects pairs of gamma rays emitted indirectly by a positron-emitting radionuclide (tracer), which is introduced into the body on a biologically active molecule.
