MAGNETOM Vida and BioMatrix special issue
„Precision medicine and adaptive technologies in medical imaging“ by Guest Editor Konstantin Nikolaou, M.D. (Department of Diagnostic and Interventional Radiology at Eberhard-Karl-University in Tuebingen, Germany)721kB
A number of innovative MR technologies is discussed in this edition of MAGNETOM Flash. For example, dedicated acceleration techniques implementing Compressed Sensing (GRASP-VIBE) to enable dynamic, free-breathing liver examinations in one comprehensive scan by the push of button and for every patient, making breath-holds and complex timing of several dynamic contrast phases unnecessary. Optimized shimming technologies such as CoilShim, one of the BioMatrix Tuners, homogenize the static magnetic field and significantly improve fat saturation and signal exploitation, e.g., in DWI of body regions difficult to image, such as the neck. SliceAdjust as an effective method to reduce susceptibility effects in whole-body DWI at 3T. Automatization of whole-body MR examinations, e.g. the Whole-Body Dot Engine, will significantly reduce overall imaging time, increase patient comfort and will potentially change our use of MRI, e.g., for an increased implementation of whole-body tumor staging. In cardiac imaging, implementation of highly accelerated real-time sequences will preserve diagnostic image quality even in challenging scenarios, such as in arrhythmic patients. Finally, complete free-breathing cardiac examinations will become possible.
Compressed Sensing Supplement
Compressed Sensing (CS) facilitates rapid MR imaging by exploiting the compressibility of medical images. This exciting new method has the potential to accelerate MRI beyond what is possible with any other method. The successful utilization of Compressed Sensing is a team play of data acquisition and image reconstruction. Read the articles in this dedicated Supplement to learn how it works.
ISMRM Edition – Issue 65
„The Rapid Imaging Renaissance“ by guest Editor Daniel K. Sodickson, M.D., Ph.D. (Vice-Chair for Research, Department of Radiology / Director, Bernard & Irene Schwartz Center for Biomedical Imaging / Principal Investigator, Center for Advanced Imaging Innovation and Research (CAI2R), New York University Langone Medical Center, New York, NY, USA2.33MB
The articles in this issue focus on advancing imaging speed. This includes streamlined workflow (see clinical protocol optimization with GOBrain, the Whole-Body Dot Engine for combined chest, abdomen, and pelvis exams or workflow improvements with Fit-Upgrades), it also includes fast, motion-insensitive imaging (such as FREEZEit in pediatric lung MRI, parotid tumor imaging with GRASP or cardiac DTI).

SCMR Edition – Issue 64
“The Future of Cardiovascular Magnetic Resonance” by guest editor Eike Nagel, M.D., Ph.D. (Director of the Institute for Experimental and Translational Cardiovascular Imaging, DZHK Centre for Cardiovascular Imaging, Head of Interdisciplinary Cardiovascular Imaging, University Hospital Frankfurt/Main, Germany)1.02MB
Quantification, speed and new applications in the field of cardiovascular MRI are the highlights of this issue. CMR is becoming fully quantitative, as evidenced by the rapid development of mapping techniques quantifying T1 and T2 relaxation and allowing the calculation of extracellular volume. Several cases in this issue demonstrate its clinical value. The increase in speed is due to faster and more patient friendly navigator sequences and to developments in parallel imaging. The greater speed allows transferring imaging methods to the heart, which were previously reserved for non-moving structures e.g. DTI. Novel sequences utilize contrast better than previous methods, as highlighted by the articles on QISS MRA.
