The diagnostic quality of breast sonography as performed with a dedicated
tomographic unit (ST) and a hand-held, high-frequency, real-time transducer
(RT) was evaluated in 76 patients. In 38 per cent of cases, ST was found to
be of equal diagnostic quality to RT. The number of instances in which ST
was judged to be better than RT was slightly greater than those in which RT
was considered better than ST (34 vs. 24 per cent) (P less than or equal to
0.10). In 3 per cent of cases, the diagnostic quality of both ST or RT was
considered to be poor. The majority of instances when the diagnostic
quality of ST was judged to be better than RT occurred in establishing a
negative diagnosis, whereas RT seemed to have greater diagnostic quality
than ST in the evaluation of a palpable mass.
