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...

Open-source practices and resources in MRI have increased substantially over the past years. This trend started with software and data being published open-source, but more recently open-source hardware designs are increasingly becoming available, too. The plentitude of open-source soft- and hardware products that are meanwhile available for all kind of MRI related purposes makes it increasingly...

Signal generation in magnetic resonance imaging (MRI) scanners relies on strong radio frequency fields. Monitoring and limiting the local energy deposition in the patient's body, measured via the specific absorption rate (SAR), represents a major challenge, especially when working with several transmit antennas in parallel. The SAR distribution cannot be measured directly but must be calculated...

Physiological parameter estimation by MRI is affected by intrinsic ambiguity in the data such as noise or model inaccuracies. Edengenet Dejene (PTB 8.14), together with Winfried Brenner (Charité), Marcus R. Makowski (TU München), and Christoph Kolbitsch (PTB 8.14), now developed a method for the uncertainty quantification of physiological parameters in dynamic contrast enhanced MRI of the liver....

Open-source low-field MRI offers completely new opportunity for health care. More than 30 international experts met in Berlin to kick-off a 3-year project to build, characterize and evaluate three open-source low-field MR scanners. The project will cover hardware and software development, physics-informed deep-learning image reconstruction and uncertainty assessment and MDR-ready documentation —...
