April 2019: Val M. Runge, MD, a note from the Editor
This issue of the journal, as always, has many outstanding articles, representing cutting edge research and technology in diagnostic imaging. A study at 7 T demonstrates the utility at that field strength for increased spatial resolution in spectroscopy for the evaluation of multiple sclerosis lesions. A second excellent article explores visualization of the glymphatic system (CSF microcirculation) on MR following IV administration of gadolinium-based contrast agents. A third article describes advances in reduction of metal artifacts and improvement in dose efficiency using photon-counting detector CT in combination with tin filtration. The remaining papers explore important advances in tomoelastography, prostate imaging (specifically DWI), and T1- and T2*-mapping, as well as assessing robustness and reproducibility in Radiomics and adverse events with gadolinium chelate administration.
