Over the past two decades researchers and clinicians in the neurosciences have witnessed a literal information explosion in the area of brain imaging and neuropsychological functioning. Until recently we could not view the nervous system except through the use of invasive procedures. Today, a variety of imaging techniques are available, but this technology has advanced so rapidly that it has been difficult for new information to be consolidated into a single source. The goal of this volume is to present information on technological advances along with current standards and techniques in the area of brain imaging and neuropsychological functioning. The quality of brain imaging techniques has improved dramatically. In 1975 one had to be content with a brain image that only offered a gross distinction between ventricular cavities, brain, and bone tissue. Current imaging techniques offer considerable precision and approximate gross neuroanatomy to such an extent that differentiation between brain nuclei, pathways, and white­ gray matter is possible. These technological advances have progressed so rapidly that basic and clinical research have lagged behind. It is not uncommon, particularly in longitudinal research, for the technical meth­ odology of a study to become obsolete while that study is still in progress. This has hampered certain aspects of systematic research and has also produced the need for a textbook that could address contemporary issues in brain imaging and neuropsychology.

CT signs of early cerebral infarction are subtle within the first 6 hours after symptom onset, but important to recognize. The CT reading panel of ECASS wants to share its experience by publishing this series of early CT scans from study patients in order to improve early recognition of ischemic infarction by CT and thus to improve patient care, and to provide material for practice. In this book each CT scan can be read with and without neuroradiological description. Follow-up scans of each case confirm early findings.
