Effect of Low Tube Voltage on Image Quality, Radiation Dose, and Low-Contrast Detectability at Abdominal Multidetector CT: Phantom Study

<table>Graph shows inversely correlative between tube current (mAs) and image noise. At identical tube current, image noise obtained at 80 kV is higher than that at 120 kV.</table>
