A novel approach to mammographic breast compression: Improved standardization and reduced discomfort by controlling pressure instead of force.
PURPOSE In x-ray mammography, flattening of the breast improves image quality and reduces absorbed dose. Current mammographic compression guidelines are based on applying a standardized force to each breast. Because breast size is not taken into consideration, this approach leads to large variations in applied pressure (force applied per unit contact area). It is the authors' hypothesis that a ...
متن کاملPattern of ipsilateral breast tumor recurrence after breast-conserving therapy.
PURPOSE To analyze the incidence and prognostic factors of ipsilateral breast tumor recurrence (IBTR) after breast-conserving therapy (BCT) in a large, population-based, single-center study with long-term follow-up. METHODS AND MATERIALS We analyzed 3595 cases in which BCT was performed in 3824 women with stage I or II breast cancer. The incidence of IBTR was analyzed over time and was based ...
متن کاملIpsilateral breast tumor recurrence after breast-conserving therapy.
In the modern era of breast-conserving therapy for early-stage breast cancer, ipsilateral breast tumor recurrence (IBTR) represents an increasingly common clinical dilemma. Two kinds of IBTRs have been described: true recurrences, which represent regrowth of uneradicated initial disease, and new primaries, which may be distinct from the index lesion in histology and location. Whether these two ...
متن کاملArm morbidity after breast-conserving therapy for breast cancer.
This study reports on 110 consecutive patients, mean age 59 years, operated on for partial mastectomy and axillary dissection. Radiotherapy of 50 Gy was administered to 75 of the patients. Most tumours were T1 tumours and all patients were NO. Lymphoedema is defined as an increase in arm volume > 10% and impaired shoulder mobility as an impairment of 15 degrees compared with the preoperative va...
متن کاملModelling Mammographic Compression of the Breast
We have developed a biomechanical model of the breast to simulate compression during mammographic imaging. The modelling framework was applied to a set of MR images of the breasts of a volunteer. Images of the uncompressed breast were segmented into skin and pectoral muscle, from which a finite element (FE) mesh of the left breast was generated using a nonlinear geometric fitting process. The c...
