Needle localization of non-palpable breast lesions.
Screening mammography identifies suspicious, non palpable mammary lesions. Mammographic needle localization (MNL) is currently being used to facilitate excision biopsy of these lesions. Thirty-two patients underwent biopsies of the breast after MNL for non-palpable lesions. Mammographic indications for biopsy consisted of microcalcifications (48%), mass or abnormal density (21%) or mass+abnorma...
متن کاملSystem analysis of spatial frequency domain imaging for quantitative mapping of surgically resected breast tissues.
The feasibility of spatial frequency domain imaging (SFDI) for breast surgical margin assessment was evaluated in tissue-simulating phantoms and in fully intact lumpectomy specimens at the time of surgery. Phantom data was evaluated according to contrast-detail resolution, quantitative accuracy and model-data goodness of fit, where optical parameters were estimated by minimizing the residual su...
متن کاملSonographic features of dense breast imaging reporting and data system 4 (BI-RADS-US4) for non-palpable breast lesions
The aim of this study was to investigate the diagnostic value of various features for differentiating between malignant and benign lesions by using the sonography for dense breast imaging reporting and data system 4 (BI-RADS-US4) for non-palpable breast lesions (dBI-RADS-US4-nPBL). The sonographic features and pathological results of a total of 102 dBI-RADS-US4-nPBLs were retrospectively analyz...
متن کاملImaging scattering orientation with spatial frequency domain imaging.
Optical imaging techniques based on multiple light scattering generally have poor sensitivity to the orientation and direction of microscopic light scattering structures. In order to address this limitation, we introduce a spatial frequency domain method for imaging contrast from oriented scattering structures by measuring the angular-dependence of structured light reflectance. The measurement ...
متن کاملAssessment of Ultrasound / Radio-guided Occult Lesion Localization in Non-palpable Breast Lesions
Objective(s): Controversy exists about the localization of non-palpable breast lesions. In many countries, the gold standard for the diagnosis of these lesions is needle localization due to its accuracy. This study sought to compare the ultrasoundand radio-guided occult lesion localization (ROLL) as a simple method with the conventional procedures in terms of their diagnostic power. Methods: Th...
