Pulmonary ventilation imaging in asthma and cystic fibrosis using oxygen-enhanced 3D radial ultrashort echo time MRI.
A previous study demonstrated the feasibility of using 3D radial ultrashort echo time (UTE) oxygen-enhanced MRI (UTE OE-MRI) for functional imaging of healthy human lungs. The repeatability of quantitative measures from UTE OE-MRI needs to be established prior to its application in clinical research. ⋯ 2 Technical Efficacy: Stage 1 J. Magn. Reson.

Support vector machine for breast cancer classification using diffusion-weighted MRI histogram features: Preliminary study.
Diffusion-weighted MRI (DWI) is currently one of the fastest developing MRI-based techniques in oncology. Histogram properties from model fitting of DWI are useful features for differentiation of lesions, and classification can potentially be improved by machine learning. ⋯ 3 Technical Efficacy: Stage 3 J. Magn. Reson. Imaging 2018;47:1205-1216.
