Does a combination of dose modulation with fast gantry rotation time limit CT image quality?
On the MDCT scanners investigated, when dose modulation is combined with fast tube rotation times, tube current saturation occurs with weaker x-ray tubes resulting in deterioration of image quality.
Our data cast doubt on the need of routine screening by brain MRI in girls with idiopathic CPP older than 6 years. Evidence-based criteria to drive clinical decision making about the use of MRI are lacking.
