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.
