[Contrast media enhancement in cranial computed tomography --studies of iodinated contrast infusion (ICI)].

The effect of infusion of iodinated contrast material on the enhancement of the computed tomography were studied in several kinds of the intracranial lesions. Especially, relationship between the degree of the enhancement and the time interval after the infusion was examined. It was found that the appearance of the enhancement effect were different according to the pathological types of the lesions. There were also time differences even in the same lesion before the full size of the lesions was demonstrated. The pathological type of the lesions could be suggested from the enhanced figures of the lesions, but the diagnosis would be more accurate in consideration of the localization of the lesions. It was thus concluded that this method was useful for the detection of the precise localization and the size of the lesions which were not so clearly demonstrated in conventional cranial computed tomography.
