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, two articles highlight advanced imaging techniques, one evaluating hippocampal sclerosis at 7 T and the other dynamic liver imaging during free-breathing using compressed sensing. Two additional articles investigate issues concerning the kidney, specifically improvements in estimation of renal ADC and IVIM-derived pure-diffusivity as well as non-invasive detection of renal fibrosis with MT-MRI. Regarding CT, advances utilizing dual energy CT are described involving improved removal of calcified carotid plaques (in extracranial carotid artery disease), improved diagnostic accuracy of segmental pulmonary embolism detection with virtual monoenergetic imaging and iodine perfusion maps, and assessment of the spatial distribution of iron in the normal liver.

​​​Investigative Radiology will publish a special issue on 'Contrast Media' in 2018. The focus is on current significant advances in knowledge regarding contrast media. Relevant topics include basic science investigations, clinical trials, innovative clinical applications, and safety. With regard to clinical papers, all organ and disease areas will be considered. Submitted manuscripts should significantly advance our knowledge concerning contrast media in MR, CT, or ultrasound.

Manuscripts are now being accepted for consideration. The deadline for submission is January 31, 2018. All papers will be subject to peer review by experts in the field and must comply with the Journal's Instructions for Authors.
