Ultrasound mammography
G Baum
Ultrasound mammography was performed with unique, high resolution equipment
which displays changes in acoustic properties of tissues through a
calibrated gray scale. Color-coded isodensitometry was used to assist in
the differential diagnosis. The rate of agreement between the ultrasound
and pathological diagnoses was 86.7%. The false negative and false positive
rates were 7.6% and 18.5%, respectively. Three problems must be solved
before ultrasound mammography can be used as a screening device: First,
additional clinical data must be accumulated. Second, the number of
ultrasonograms needed for diagnosis must be reduced. Third, special
equipment designed for ultrasound mammography must be developed.
