Indeterminate or suspicious breast lesions detected initially with MR imaging: value of MRI-directed breast ultrasound.

Rationale And Objectives: To retrospectively determine the value of magnetic resonance imaging (MRI)-directed breast ultrasonography (US) in the evaluation of indeterminate or suspicious lesions identified on contrast-enhanced, breast MRI.

Materials And Methods: A total of 395 patients presenting for breast MRI during a 4-year period was retrospectively reviewed. Seventy-one patients were recommended for MRI-directed US for further characterization of indeterminate or suspicious breast lesions detected on MRI.

Correlation between core biopsy and excisional biopsy in breast high-risk lesions.

Background: The purpose of the current study was to compare the prevalence of invasive or in situ cancer at excisional biopsy in patients with image-guided core needle biopsy (CNB)-proven atypical ductal hyperplasia (ADH), atypical lobular hyperplasia (ALH), or lobular carcinoma-in-situ (LCIS). Factors affecting the upgrade rate to malignancy were also identified.

Methods: Patients diagnosed with ADH, ALH, or LCIS on image-guided CNB (stereotactic or ultrasound) from 1995 to 2005 were identified through radiologic and surgical databases.

Imaging characteristics of malignant lesions of the male breast.

Most men referred for breast imaging have palpable lumps, breast enlargement, or tenderness. Most of the evaluated lesions are benign. Male breast cancer accounts for less than 1% of total male breast lesions.
