“…In group A (17 women with single-duct nipple discharge), galactography performed on seven patients showed a dilation res equipaggiati con trasduttori lineari ad alta frequenza (7,(5)(6)(7)(8)(9)(10)(10)(11)(12)(13) per i tessuti superficiali. Sono state effettuate scansioni radiali ed antiradiali al capezzolo, prestando attenzione a tutto l'albero duttale seguendo i dotti galattofori a partire dalla regione retroareolare fino alle diramazioni più periferiche, quando visibili.…”

“…Several studies recently emphasised the importance and usefulness of breast US in the study of breast diseases, not only mente di guidare la mano dell'operatore nella esecuzione di manovre mini-invasive (agoaspirati e agobiopsie), ma anche quale prima indagine di diagnostica strumentale nello studio del seno denso giovanile [3,4,8,13]. In particolare alcuni autori hanno dimostrato la capacità dell'ecografia di poter effettuare la diagnosi della patologia duttale benigna e la diagnosi differenziale con la patologia maligna della mammella [14][15][16][17].…”

“…Tra le condizioni patologiche benigne più comuni sono comprese il papilloma mammario sia singolo (spesso localizzato in sede retroareolare in contiguità con i dotti galattofori principali) che multiplo (a localizzazione più periferica ad origine dai dotti lobari terminali) e la papillomatosi giovanile, definita come singola entità patologica dal 1980 che si presenta nelle giovani donne in un'età compresa tra i 23 ed i 32 anni [18][19][20][21][22]. Non tutti gli autori sono però d'accordo sulla natura benigna di tali condizioni patologiche: Yang et al [7] riportano che il papilloma solitario si associ ad un incremento del rischio del 1,5%-2% di sviluppare un carcinoma e ne consigliano l'escissione chirurgica in tutti i casi diagnosticati, mentre Cardenosa e Eklund [23] dimostrano nel suo articolo che il papilloma solitario originantesi in sede centrale non debba L. Ballesio et al: Adjunctive diagnostic value of ultrasonography evaluation in patients with suspected ductal breast disease because it is able to define the solid or liquid nature of a lesion and provide guidance in minimally invasive manoeuvres (needle aspiration and needle biopsy), but also as it represents a first-line modality for the study of the dense breast tissue of younger women [3,4,8,13]. In particular, some authors have demonstrated the ability of breast US to provide a diagnosis of benign ductal disease and differentiate it from breast malignancy [14][15][16][17].…”

“…Issues also exist with the alternative imaging technologies: MRI and Ultrasound. Despite the fact that recent research has shown that MRI has a negative predictive value of 99% [3], the cost and issues with the sensitivity and specificity of these alternative imaging modalities, particularly ultrasound, preclude their widespread use [4,5].…”

Abstract-Microwave Imaging is one of the most promising emerging imaging technologies for breast cancer detection, and exploits the dielectric contrast between normal and malignant breast tissue at microwave frequencies. The development of many UWB Radar imaging approaches requires the use of accurate numerical models for the propagation and scattering of microwave signals within the breast. The Finite-Difference Time-Domain (FDTD) method is the most commonly used numerical modelling technique used to model the propagation of Electromagnetic (EM) waves in biological tissue. However, it is critical that an FDTD model accurately represents the dielectric properties of the constituent tissues, including tumour tissues, and the highly correlated distribution of these tissues within the breast. This paper presents a comprehensive review of the latest findings regarding dielectric properties of normal and cancerous breast tissue, and the heterogeneity of normal breast tissue. Furthermore, existing FDTD models of the breast described in the literature are examined.

Abstract-Microwave imaging is one of the most promising emerging imaging technologies for breast cancer detection. Microwave imaging exploits the dielectric contrast between normal and malignant breast tissue at microwave frequencies. Many UWB radar imaging techniques require the development of accurate numerical phantoms to model the propagation and scattering of microwave signals within the breast. The Finite Difference Time Domain (FDTD) method is the most commonly used numerical modeling technique used to model the propagation of Electromagnetic (EM) waves in biological tissue. However, it is critical that an FDTD model accurately represents the dielectric properties of the constituent tissues and the highly correlated distribution of these tissues within the breast. This paper presents a comprehensive review of the dielectric properties of normal and cancerous breast tissue, and the heterogeneity of normal breast tissue. Furthermore, existing FDTD models of the breast are examined and compared. This paper provides a basis for the development of more geometrically and dielectrically accurate numerical breast phantoms used in the development of robust microwave imaging algorithms.
