The authors describe a method that permits the determination of the precise intraventricular iodine concentration after metrizamide computed tomographic ventriculography. There is an observed linear relationship between computed tomography number (Hounsfield units) and iodine concentration. This relationship may be used to provide the basis for a method of evaluating ventricular fluid dynamics. This, in turn, is useful for the determination of the indications for a shunting procedure and for the evaluation of shunt function in a patient with an existing shunt.
作者描述了一种方法,该方法能够在甲泛葡胺计算机断层脑室造影术后测定脑室内碘的精确浓度。计算机断层扫描数值(亨斯菲尔德单位)与碘浓度之间存在明显的线性关系。这种关系可用于为评估脑室流体动力学的方法提供依据。反过来,这对于确定分流手术的适应症以及评估现有分流患者的分流功能很有用。
