At the annual meeting of the Triological Society in Palm Beach, Fla, Terrence K. Trapp, MD, and coauthors, Los Angeles, reported the use of a new needle to perform magnetic resonance—guided aspiration cytology in three patients with head and neck lesions. The new needle is constructed of c-276 stainless steel, which has a very high nickel content and low ferromagnetic properties. This results in minimal image artifact. A new technique of needle placement was also developed, which takes advantage of the multiplanar imaging capability of magnetic resonance imaging. Oblique images, parallel and perpendicular to the plane of the needle, provide precise localization of the needle tip. The authors state that this technology may be very useful in the evaluation of lesions that would be otherwise inaccessible to biopsy.
