[Comparison between current and high resolution ultrasound for diagnosis of breast lesions].
OBJECTIVE
To assess the value of high-resolution ultrasound in the diagnosis of breast lesions.


METHODS
Fifty women with a clinically suspicious breast mass were examined with mammography, conventional and high-resolution sonography. Ultrasound was performed with a linear-array 7.5-mHz transducer and an annular-array 13.0 MHz transducer.


RESULTS
Histology showed carcinoma in 28 patients, fibrocystic changes in 20 and fibroadenoma in 2. High-resolution ultrasound characterized 18 lesions more accurately than conventional ultrasound, including 13 carcinomas, 3 fibrocystic changes and 2 fibroadenomas. The size of 8 carcinomas was measured more accurately with high-resolution ultrasound than with conventional ultrasound.


CONCLUSIONS
High-resolution ultrasound is more valuable in the differentiation and size determination of breast lesions than conventional ultrasound.
