Several studies have shown that it is possible to use the parenchymal patterns disclosed by mammography to differentiate various groups with a high risk of developing breast cancer. Accordingly, a patient series of 597 women who had undergone mammography during the period 1971-1975 was examined and classified according to Wolfe's system. A follow-up of 513 patients five to nine years after the mammography revealed no statistical difference in the tendency to develop breast cancer using Wolfe's parenchymal pattern method. The study shows that those in the group with pronounced fibroadenomatous changes, which were primarily studies radiologically, have an incidence of breast cancer three times as high as that found in the population as a whole.

In order to adequately visualize the ossicles and other fine structures in the middle ear, sophisticated radiological methods are essential. The temporal bone has been studied with hypocycloidal tomography using conventional films and xerotomography in 60 patients with cholesteatoma. In 53 of the patients xerotomography gave good results while conventional tomography gave good results in only 38 patients. The superiority of xerotomography to conventional radiological methods is stressed. The only drawback is the high radiation dose to the patient.
