Free-breathing dynamic contrast-enhanced MRI for assessment of pulmonary lesions using golden-angle radial sparse parallel imaging.
Dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI) has been shown to be a promising technique for assessing lung lesions. However, DCE-MRI often suffers from motion artifacts and insufficient imaging speed. Therefore, highly accelerated free-breathing DCE-MRI is of clinical interest for lung exams. ⋯ 2 Technical Efficacy: Stage 1 J. MAGN. RESON. IMAGING 2018;48:459-468.

Aortic valve stenosis and aortic diameters determine the extent of increased wall shear stress in bicuspid aortic valve disease.
Use of 4-dimensional flow magnetic resonance imaging (4D-flow MRI) derived wall shear stress (WSS) heat maps enables identification of regions in the ascending aorta with increased WSS. These regions are subject to dysregulation of the extracellular matrix and elastic fiber degeneration, which is associated with aortic dilatation and dissection. ⋯ 2 Technical Efficacy: Stage 2 J. MAGN. RESON. IMAGING 2018;48:522-530.

Consistency of Multiple Renal Functional MRI Measurements Over 18 Months.
Identification of patients with progressive chronic kidney disease (CKD) and those likely to respond to candidate therapeutics is urgently needed. Functional MRI measurements have shown promise. However, knowledge about the consistency of the measurements is essential to conduct longitudinal studies. ⋯ 1 Technical Efficacy: Stage 1 J. MAGN. RESON. IMAGING 2018;48:514-521.

Using support vector machine analysis to assess PartinMR: A new prediction model for organ-confined prostate cancer.
Partin tables represent the most widely used predictive tool for prostate cancer stage at prostatectomy but with potential limitations. ⋯ 3 Technical Efficacy: Stage 2 J. MAGN. RESON. IMAGING 2018;48:499-506.
