Accuracy of sonographically guided 14-gauge core-needle biopsy: results of 715 consecutive breast biopsies with at least two-year follow-up of benign lesions.

Purpose: The objective of this study was to examine the diagnostic accuracy of sonographically guided 14-gauge core-needle biopsy (CNB).

Methods: Sonographically guided 14-gauge CNBs of 715 breast lesions were performed in 652 patients. Histopathologic results were correlated with imaging findings, and repeat biopsy was recommended in the cases of discordance between the radiologic and pathologic results.

Color Doppler imaging of fibroadenomas of the breast with histopathologic correlation.

Purpose: This study was conducted to characterize the spatial distribution of blood vessels in breast fibroadenomas.

Methods: We performed a prospective study to map the anatomic distribution of the vessels in 29 fibroadenomas of the breast using color Doppler sonography. We categorized the detected vessels according to their location in or on the fibroadenoma, counted the different types of vessels, and tested for correlations between vessel distributions or numbers and histopathologic findings.

Dedicated screening mammography for diagnosis of small breast cancer.

Breast cancer is the most common malignancy in women, and early diagnosis is a cornerstone of successful treatment. Mammography is the sole acceptable method for breast cancer screening, but its efficacy is still disputable. The aim of this study was to determine whether the influence of dedicated mammographic team skills could improve the diagnostic accuracy of screening mammography and detection of small breast cancers.

Using sonography to screen women with mammographically dense breasts.

Objective: Mammographically dense breast tissue has been reported both as a cause of false-negative findings on mammography and as an indicator of increased breast cancer risk. We conducted this study to evaluate the role of breast sonography as a second-line screening test in women with mammographically dense breast tissue.

Materials And Methods: Between January 2000 and January 2002, 1517 asymptomatic women with dense breasts and normal mammography and physical examination findings underwent physician-performed breast sonography as an adjunct screening test.
