Comparative Study Controlled Clinical TrialComparison of two different injection rates of gadoxetic acid for arterial phase MRI of the liver.
To compare two different injection rates for gadoxetic acid-enhanced hepatic arterial phase images on hepatic dynamic MRI. ⋯ Injection rates of 2 mL/second and 1 mL/second provided comparable image qualities on arterial phase images of hepatic dynamic MRI using gadoxetic acid.

Scan-rescan reproducibility of carotid atherosclerotic plaque morphology and tissue composition measurements using multicontrast MRI at 3T.
To evaluate interscan reproducibility of both vessel morphology and tissue composition measurements of carotid atherosclerosis using a fast, optimized, 3T multicontrast protocol. ⋯ The results from the multicontrast high-resolution 3T MR study show high reliability for carotid morphology and plaque component measurements. 3T MRI is a reliable tool for longitudinal clinical trials, with shorter scan time compared to 1.5T.

Adaptive non-local means denoising of MR images with spatially varying noise levels.
To adapt the so-called nonlocal means filter to deal with magnetic resonance (MR) images with spatially varying noise levels (for both Gaussian and Rician distributed noise). ⋯ The new noise-adaptive method was demonstrated to outperform the standard filter when spatially varying noise is present in the images.

Flow-independent T(2)-prepared inversion recovery black-blood MR imaging.
To develop a magnetization preparation method to achieve robust, flow-independent blood suppression for cardiac and vascular magnetic resonance imaging (MRI). ⋯ T(2)Prep-IR may overcome the flow dependence of DIR by providing robust flow-independent black-blood images.
