The separate imaging of fat and water rich tissue is a frequent objective in magnetic resonance imaging (MRI). An efficient solution is provided by the Dixon technique where both compartments are excited simultaneously and the signals are later separated based on their different temporal evolution. At the 'ultrahigh' MRI field strength of 7T, the frequency shift between fat and water protons is...

Last fall, the research paper "Wirelessly interfacing sensor-equipped implants and MR scanners for improved safety and imaging" by Berk Silemek, Lukas Winter, and colleagues was published in Magnetic Resonance in Medicine (MRM). This article was now chosen as an MRM Highlights Pick "… because they openly shared design files and software for the MRI implant sensor they developed" (see gitlab1.ptb...

To accelerate the inherently slow acquisition process in magnetic resonance imaging (MRI) is one of the core tasks of MRI research since the very invention of this imaging modality. It was thus a huge mile-stone, therefore, when Prüssmann and coworkers recognized, 25 years ago, how the different spatial sensitivities of the various coil elements in modern MRI receivers could be utilized to speed...

Magnetic resonance imaging (MRI) not only provides images from inside the human body, but the method also allows various functional physiological parameters to be measured directly. An important example of this is spatially and temporally resolved velocity profiling of flowing blood in large vessels, such as the aortic arch. However, the phase-contrast MRI commonly used for this purpose often...

MRM Editor's Picks

In August 2023, the research paper Wirelessly interfacing sensor-equipped implants and MR scanners for improved safety and imaging, by Berk Silemek and coworkers from PTB 8.11 was first published online in Magnetic Resonance in Medicine (MRM, doi: 10.1002/mrm.29818). The paper demonstrates how signals from small and cheap sensors at the tip of a medical implant, e.g. the lead of a cardiac...
