February 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 and technology in diagnostic imaging. Articles involving MR and CT are featured. Regarding MR, three articles highlight advances in imaging technique, for improved imaging of intracranial arteriovenous shunts, for the evaluation of (or absence thereof) spermatogenesis and utilizing DWI as a response marker in prostate cancer bone metastases. Three additional articles investigate issues concerning MR contrast media, one confirming the safety of Dotarem in pediatric subjects under 2 years of age, one demonstrating in the pediatric population the absence of dentate nucleus hyperintensity following Gadovist injection - and thus the stability of this macrocyclic agent, and the last evaluating the effects of perinatal exposure to GBCAs. Regarding CT, two articles are featured, both illustrating the utility of dual energy - one for improved visualization of brain edema and the other focusing on advanced calcium subtraction for improved luminal visualization.
