This issue of the journal, as always, has many outstanding articles, representing cutting edge research and technology in diagnostic imaging. Critical new developments and findings in our field are presented, including that in MR, CT, contrast media use, and deep learning. Not to be missed is the editor’s pick article, which demonstrates (for the first time) the improvements that can be gained at 7 T using advanced metal-artifact reduction techniques. In regard to contrast media, a very important article evaluates individualized scan protocols in abdominal CT looking at radiation vs contrast dose optimization. Advancements in MR imaging technique are highlighted in two articles, one focusing on MP2RAGE, and the other on T2 quantification strategies in the abdominal-pelvic region. In regard to deep learning, a single article depicts the impact of deep learning reconstruction on single-shot FSE T2-weighted imaging of the uterus. Three outstanding articles present major advances in clinical imaging made possible with photon counting detector CT - focusing on (1) cardiac vascular calcium removal (and thus evaluation of coronary artery narrowing), (2) extracellular volume quantification with cardiac late enhancement scanning and (3) emphysema quantification.
