[Effect of contrast material pushed with saline solution using dual injection on enhancement of aorta, portal vein, and liver parenchyma in multislice CT of the liver].
We evaluated the effect of the enhancement value of the abdominal aorta, portal vein, and liver parenchyma by the saline flush technique. One hundred eight patients who underwent multislice CT of the liver were randomly divided into four groups: 100 ml of contrast material (Iomeprol 300 mgI/ml or 350 mgI/ml) only and 100 ml of contrast material (300 mgI/ml or 350 mgI/ml) flushed with 50 ml of saline solution at a rate of 5 ml/sec. The saline flush technique demonstrated statistically significantly greater portal enhancement. Therefore, we consider that this technique contributes to the visualization of three-dimensional CT portography.
