Biomedical Magnetic Resonance

Department 8.1



The department engages in method development for magnetic resonance imaging (MRI) and spectroscopy (MRS).

Specific methodological aspects of MRI are covered by currently four research groups: physical basics and safety (8.11); quantitative MRI and MRS applications in neuroscience studies in cooperation with clinical research groups (8.12); data acquisition and image reconstruction algorithms for motion correction and multimodal imaging (8.13); excitation and acquisition techniques specifically designed to harvest the potential of 'ultrahigh' (7T) magnetic fields (8.14).
Central research tool is a whole-body 3-tesla MR scanner. Additionally, the department is engaged in the Berlin Ultrahigh Field Facility which is operating a 7-tesla whole body scanner.


In an international collaboration led by University College London, a reference phantom for quantitative MRI imaging of the heart, called T2MES, was developed and tested over twelve months. Spatially resolved measurements of the transverse relaxation time T2 provide clues to edema, inflammation, and other diseases of the myocardium, but in clinical practice measurement results are often...

In a collaboration of PTB departments 1.6 and 8.1 with the Simone Kühne's group at the Max Planck Institute for Human Development in Berlin investigate, it was investigated on a group of volunteers whether and, if so, how the human brain reacts to ultrasound stimuli when these are offered at sound levels below the individual hearing threshold. By functional MRI measurements it was found that a...

The predecessor had served us well for more than 13 years, but eventually it was time to replace it. On May 09, 2023, PTB's new 3T MRI arrived on our premises and was lowered into the historic "Quarzuhrenkeller". Distinguishing feature of the new Cima.X model from Siemens Healthineers, first installation of its kind in Europe, are the powerful gradients. Rated at 200 mT/m they outperform the...
