[Technical aspects of breast sonography. Experience with an immersion scanner (Octoson) (author's transl)].

The experience with the sonographic examination of 80 patients with an Octoson body unit is described. It was found that with the present technique immersion of the breast in most cases is less satisfactory than compression of the breast. The compound scan improves the information as compared with a single scan up to a point. Immersion sonography, like all other types of ultrasound examination, is at present not satisfactory as the sole method for examining the breast. As an addition to mammography and palpation, sonography is, however, already an important complementary method.
