This issue of the journal, as always, has many outstanding articles, representing cutting edge research and technology in diagnostic imaging. The issue is one with a special focus, that is ‘Speed’ in MR, and presents 11 papers. “Speed” is a critical issue for MR, with the definition of speed including not just how fast the scan itself can be but also extending to the robustness of the technique and the speed of data sampling. Regardless of anatomic area and desired specific tissue contrast, sparse imaging and SMS - along with other innovative acquisition techniques - can be applied, and will fundamentally impact the clinical utilization of MR, with further developments therein extending over at least the next decade.

​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 will be accepted for consideration beginning in October. 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.
