✦ Synopsis

In an article published in a previous issue of this journal, Moscatel et a1 reported the results of an evaluation of various biopsy needles and devices for compatibility with MR procedures (1). It was found that most of the commercially-available biopsy devices were not useful for MRguided biopsy procedures owing to the presence of ferromagnetism and associated artifacts.

Since the publication of that report, additional biopsy needles, localization wires, and a biopsy gun have been developed that are manufactured from a metal that is high in nickel content (see Table 1). Recently, we tested these new devices for MR-compatibility using methods similar to those described in the article by Moscatel et al.

As a result of this testing, we found three different biopsy needles, a localization wire, and a biopsy gun to have American Hpalth Servicrs Cnrp. Newport Reach. CA IF.G.S.1 and Future Diagnnsties, Inc, Los h g e l e s , CA (v. J.S.1.
