Abstract

Magnetic resonance imaging (MRI) has been described as arguably the single most powerful soft-tissue imaging technique ever conceived and realized by humankind. To employ this technology solely for diagnosis is shortsighted. As a logical consequence interventional procedures using MRI guidance have increased in interest during the last couple of years. Central to the success and safety of MRI guided procedures is the accurate visualization of the interventional instruments relative to the surrounding anatomy. A variety of methodologies for visualizing and automatically tracking instruments, including needles, RF and laser ablation devices, catheters, and guidewires have been developed and introduced to help the interventionalist to safely guide the device towards the target region. This article describes characteristics of the most commonly used localization techniques used for MRI guided interventional procedures. Clinical Applications such as biopsies and thermal ablation techniques are discussed.
