Sept. 2, 2004 — Magnetic resonance imaging (MRI)-guided interstitial radiofrequency (RF) thermal ablation (ITA) has a high success rate in primary kidney tumors, according to the results of a phase II ...

Researchers warn that implanted nerve cuff electrodes can trigger unintended nerve stimulation and pain during MRI scans.

Radio frequency (RF) probes designed like by microstrip patch antennas create uniform and strong magnetic field in high frequency MRI machines, unlike convention coil and bird cage shaped coils used ...

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 ...

High-resolution magnetic resonance imaging (MRI) machines can work better by changing the structure of radio probes from coils to antennas. How can you make a high-frequency MRI machine more precise?
