Purpose: To determine the utility and histopathologic importance of ultrasonographic (US) depiction of breast lesions detected with magnetic resonance (MR) imaging.
Materials And Methods: Retrospective review was performed of 654 consecutive breast MR examinations performed from November 1999 to February 2001. This yielded 64 patients with 93 suspicious, nonpalpable, mammographically occult lesions evident on MR images and recommended for biopsy, for which directed US assessment was performed.
Objective: The purpose of this study was to analyze features of breast lesions detected on MR imaging that had subsequent biopsy and to determine the positive predictive value (PPV) of these features.
Materials And Methods: Retrospective review was performed of 100 consecutive solitary MR imaging-detected breast lesions that had MR imaging-guided needle localization and surgical excision. We described lesions, using terms found in a proposed breast MR imaging lexicon.
Objective: MR imaging of the breast can depict cancer that is occult on mammography and at physical examination. Our study was undertaken to determine the ease of performance and the outcome of MR imaging-guided needle localization and surgical excision of breast lesions.
Materials And Methods: Retrospective review revealed 101 consecutive breast lesions that had preoperative MR imaging-guided needle localization with commercially available equipment, including a 1.
Objective: The purpose of this study was to determine the frequency of and factors associated with performing one therapeutic operation after percutaneous diagnosis of nonpalpable breast cancer.
Materials And Methods: Retrospective review was performed of records of 350 consecutive women who had therapeutic surgery after percutaneous imaging-guided core biopsy diagnosis of nonpalpable breast cancer. Records were reviewed to determine the frequency of performing one operation and associated factors.
