Magnetic resonance imaging (MRI) is one of medicine's most powerful diagnostic tools. But certain tissues deep inside the body—including brain regions and delicate structures of the eye and orbit that are of particular relevance for ophthalmology—are difficult to image clearly. The problem is not the scanner itself, but the hardware that sends and receives radio signals.

Now, researchers led by Nandita Saha, a doctoral student in the Experimental Ultrahigh Field Magnetic Resonance lab of Professor Thoralf Niendorf at the Max Delbrück Center have developed an advanced materials-based MRI antenna that overcomes these limitations—delivering enhanced images more quickly and that can be used in existing MRI machines. The research was published in Advanced Materials.

Niendorf and his team worked closely with researchers at Rostock University Medical Center, combining expertise in MRI physics with clinical ophthalmology and translational imaging. The Rostock team is also supporting clinical validation of the technology.
