Diffusion tensor imaging (DTI) with retrospective motion correction for large-scale pediatric imaging
Journal of Magnetic Resonance Imaging, 06/12/2012
Holdsworth SJ et al. – This work suggests that, apart from the rare instance of continuous motion throughout the scan, high–quality DTI brain data can be acquired using the proposed integrated sequence and reconstruction that uses a retrospective approach to motion correction. In addition, the authors demonstrate a substantial improvement in overall image quality by combining phase correction with complex averaging, which reduces the Rician noise that biases noisy data.
