July 2015: 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. A very important article, investigating a major potential safety issue, is that by Carlo Cosimo Quattrocchi, evaluating further the dentate nucleus T1 hyperintensity that is seen following gadodiamide (Omniscan) administration in patients with normal renal function. Additional articles of special interest discuss important developments in MR, CTA, real time optical tissue characterization (during image-guided percutaneous intervention), dark-field radiography, and MR-PET. Of particular note are two of these articles. In terms of further developments in MR technique, and in particular improvements in scan time, it is shown that simultaneous multislice EPI with blipped controlled aliasing in parallel imaging results in higher acceleration that can remarkably reduce acquisition time in DTI of skeletal muscle. In the other of these two articles, it was shown that tissue blood content, oxygenation level, lipid content, and tissue density all showed significant differences when a needle tip was guided from healthy tissue to tumor and can therefore be used to identify tissue boundaries during percutaneous image-guided interventions.

Call for Papers: Special Issue on 'Advances for Clinical Imaging involving Data Sparsity in MRI and CT
Investigative Radiology will publish a special issue on 'Advances for Clinical Imaging involving Data Sparsity in MRI and CT' in early 2016. The focus of this special issue will be on advances in the field of data sparsity and related advances in imaging techniques for magnetic resonance and computed tomography in terms of higher temporal and spatial resolution, acquisition speed and radiation dose reduction. With regard to clinical papers involving this topic, all organ and disease areas will be considered. Accepted manuscripts can involve either basic or clinical research and should lead to advancing our understanding of data sparsity in MR and CT imaging and promoting its potential clinical application by significant milestones of innovation.

Manuscripts are currently being accepted for consideration for the issue. The deadline for submission is July 5, 2015. The deadline has been extended due to the difficulty of many authors in preparing their submissions due to the time frame of the ISMRM meeting this year. All papers will be subject to peer review by experts in the field and must comply with the Journal's Instructions for Authors.

We look forward to receiving your submissions.
