October 2018: Val M. Runge, MD, a note from the Editor
This issue of the journal, as always, has many outstanding articles, representing cutting edge research in diagnostic imaging. More specifically, it is the second of two focused special issues concerning contrast media in diagnostic imaging. The October issue deals with topics concerning both MR and CT. The first article is a critically important review article, discussing the dechelation (transmetalation) that occurs in vivo with linear gadolinium chelates, together with the consequences and associated safety concerns, in view of the recent health care rulings across the world. Eight articles follow, five clinical MR studies, and three CT studies - one clinical and two involving potential new contrast media. The MR studies involve the liver, breast and prostate, with accelerated imaging a specific subtopic. An important statement for CT comes from an article evaluating safety guidelines, concluding that the incidences of CIN and mortality at 35 days are significantly higher in stage 4 as opposed to stage 3 chronic kidney disease.
