[Mammography with minimal radiation dosage. Comparative studies on various imaging systems].
Using an MR-film-screen combination for mammography, only 8% of the usual radiation dose was found to be necessary. This corresponds with an average skin dose of 0.55 R per exposure. The new technique resulted in visible improvement of contrast. Some loss of detail affected in particular the recognition of macrocalcification. As the sole method for the early diagnosis of occult carcinomas of the breast, it will therefore be necessary to improve image quality. The system is suitable for control examinations and investigation of special problems. The use of the MR system with non-screen film in two planes is discussed in relation to dose reduction.
