title: Quantitative aspects of computed tomography of the blood and cerebrospinal fluid.
abstract: Computed tomographic (CT) scans of fresh and coagulated blood in vitro as well as calcium and iron solutions demonstrate that the increased absorption seen in hematomas is primarily a reflection of hemoconcentration: calcium plays essentially no role in this increased absorption, while iron makes a minimal contribution. In vitro studies of cerebrospinal fluid (CSF) indicate that CT scanning is insensitive to pathological elevations of CSF protein.
