title: [Mammography and ultrasound in the diagnosis of clinically occult breast cancer].
abstract: 105 biopsies of nonpalpable breast lesions were performed because of suspect X-ray findings. 68 lesions were preoperatively marked under X-ray control, 37 under ultrasound control. Histological examination revealed invasive and in situ carcinomas in 8 and 13% of the cases, respectively. The sensitivity of X-ray mammograms was superior to ultrasound, whereas the predictive value of ultrasound in the presence of suspect findings was superior to x-ray examination. However, because of its low sensitivity, sonographic examination cannot be recommended as a screening procedure in the diagnosis of nonpalpable breast lesions.
