title: Technologic considerations for breast tumor size assessment.
abstract: Breast tumor staging and treatment response is primarily determined by tumor size. Presently there are four techniques to measure breast cancer size: (1) palpations, (2) mammography, (3) ultrasonography, and (4) MR imaging. This article reviews the applications and limitations of each technique and the improvements MR imaging can provide.
