Isotropic morphometry and multicomponent T1 ρ mapping of human knee articular cartilage in vivo at 3T.
The progressive loss of hyaline articular cartilage due to osteoarthritis (OA) changes the functional and biochemical properties of cartilage. Measuring the T1 ρ along with the morphological assessment can potentially be used as noninvasive biomarkers in detecting early-stage OA. To correlate the biochemical and morphological data, submillimeter isotropic resolution for both studies is required. ⋯ 2 Technical Efficacy: Stage 1 J. Magn. Reson. Imaging 2018;48:1707-1716.

Preoperative tumor texture analysis on MRI predicts high-risk disease and reduced survival in endometrial cancer.
Improved methods for preoperative risk stratification in endometrial cancer are highly requested by gynecologists. Texture analysis is a method for quantification of heterogeneity in images, increasingly reported as a promising diagnostic tool in various cancer types, but largely unexplored in endometrial cancer. ⋯ 2 Technical Efficacy: Stage 2 J.

3D ultrashort echo time MRI of the lung using stack-of-spirals and spherical k-Space coverages: Evaluation in healthy volunteers and parenchymal diseases.
Ultrashort echo time (UTE) has been shown to improve lung MRI quality in three dimensions. The evaluation of 3D-UTE stack-of-spirals VIBE (3D-USV) sequence for parenchymal diseases and a comparison of performance with that of a spherical mode of acquisition is needed. ⋯ 2 Technical Efficacy: Stage 1 J.
