Abstract

The stainless steel ring (SSR; Figure 1) is a commonly used Chinese intrauterine device (IUD) that has a typical appearance when shown on sonography. Considering the large number of Chinese immigrants coming to the United States and the 2.7 million Chinese-born immigrants currently living here, it is not surprising that many family practitioners, obstetricians, sonographers, and sonologists will see the SSR at some point in their careers. General knowledge about the effectiveness, risks, and sonographic appearance of the SSR is important for physicians who may encounter this particular IUD in their practices. To the best of our knowledge, no previous reports of the sonographic appearance of the SSR have been reported in the English language imaging literature.
