Expert Insights: Hidden Gems from Application Specialists at Siemens Healthineers.
Khaled Khames is a physicist in Cairo, Egypt. His favorite feature is the Trigger Delay parameter, to achieve motion artifact free images in the heart region.
You can use it to optimize image quality in noncontrast-enhanced MR angiography when using a triggered 3D TrueFISP or FLASH sequence
– to image the whole heart, coronaries, or the aorta.

Milestones and Applications of High-Resolution #7T MRSI
by Gilbert Hangel, PhD; et al. (Medical University Vienna, Austria).
The authors introduced a 7T MRSI method that combines free induction decay acquisition with concentric circle readout and short TE/TR that allows fast 3D coverage of the human brain.

This article demonstrates first results of applications in pathologies such as: brain tumors, multiple sclerosis, and epilepsy.

Deep Resolve Boost (DRB) and Sharp (DRS) for Diffusion: ADC Phantom Evaluation by Hyun--Soo Lee, PhD; Thomas Benkert, PhD; et al. (Siemens Healthineers)

Using a dedicated diffusion phantom, this study systematically and objectively assessed whether the use of DRB and DRS impacts the ADC for DWI.
The authors conclude that that it does not influence ADC values. This holds true for different protocol settings.

4D-MRI for Treatment Planning of Liver Tumors by Jess Scholey, PhD; et al. (Dept of Radiation Oncology, University of California, San Francisco, USA).
This study demonstrates the feasibility of using hepatobiliary contrast-enhanced 4D-MRI to delineate gross liver tumors directly throughout the respiratory cycle. 4D-MRI may improve radiation treatment of liver lesions and reduce the risk of marginal misses. https://marketing.webassets.siemens-healthineers.com/747a5ae9ce74018b/1f90550188ea/siemens-healthineers_magnetom-world_scholey_4D-MRI.pdf
