Real-time high resolution ultrasonography of solid breast masses: use of a 10-MHz mechanical sector transducer with a water bag.
We evaluated the diagnostic accuracy of real-time high-resolution ultrasonography (RHUS) for solid breast masses, using a 10-MHz mechanical sector transducer with a water bag. A total of 103 breast nodules in 100 women were analyzed. The nodules consisted of 42 carcinomas, 10 fibroadenomas, 38 mastopathies, and 13 miscellaneous lesions. Of them, 72.8% were less than 2 cm in size. Diagnostic accuracy was correlated with the size and pathology of the nodules. Sensitivity, specificity, and accuracy were 95.2%, 83.6%, and 88.3% for carcinomas, 90.0%, 88.2%, and 88.3% for fibroadenomas, and 50.0%, 98.5%, and 80.6% for mastopathies, respectively. The overall rate of diagnostic accuracy was 74.8%. The rate of accuracy according to mass size were 87.3% (-1 cm), 87.2% (1-2 cm), 88.0% (2-5 cm) and 100% (5 cm-). False positive cases (n = 10) included seven mastopathies, two granulomas, and one fibroadenoma. False negative cases (n = 2) included one fibroadenoma and one abscess. RHUS, using a 10-MHz mechanical sector transducer, was an excellent method for the diagnosis of solid breast masses.
