Dielectric characterization has significant potential in several medical applications, providing valuable insights into the electromagnetic properties of biological tissues for disease diagnosis, treatment planning, and monitoring of therapeutic interventions. This work presents the use of a custom-designed electromagnetic characterization system, based on an open-ended coaxial probe, for discriminating between benign and malignant breast tissues in a clinical setting. The probe's development involved a well-balanced compromise between physical feasibility and its combined use with a reconstruction algorithm known as the virtual transmission line model (VTLM).

Objective:: To assess the clinical performance of the halo sign in tomosynthesis and synthesized 2D mammography, and to identify age groups where its diagnostic value may be greater.
Methods:: 183 patients with nodules were recalled from the breast screening programme (with tomosynthesis and 2D synthesized mammograms). The patients were separated into two groups, 45-49 years and 50-69 years, and depending on the presence or not of halo sign.
