The research here presented aims at developing a new, promising method for the imaging diagnostics of breast lesions - ultrasound tomography (UST). A currently implemented device enables the reconstruction three complementary images for each coronal breast section. Based on in vivo breast examination, the authors developed an approach to breast diagnostics which employs ultrasound transmission and reflection tomography imaging. The obtained transmission images of ultrasound speed distribution show good correlation of glandular tissue areas with their visualization on MRI images...

Microwave imaging is an emerging breast cancer diagnostic technique, which aims at complementing already established methods like mammography, magnetic resonance imaging, and ultrasound. It offers two striking advantages: no-risk for the patient and potential low-cost for national health systems. So far, however, the prototypes developed for validation in labs and clinics used costly lab instruments such as a vector network analyzer (VNA). Moreover, the CPU time required by complex image reconstruction algorithms may not be compatible with the duration of a medical examination...

REVIEW
James S Wysock, Herbert Lepor
The primary goal of a focal therapy treatment paradigm is to achieve cancer control through targeted tissue destruction while simultaneously limiting deleterious effects on peri-prostatic structures. Focal therapy approaches are employed in several oncologic treatment protocols, and have been shown to provide equivalent cancer control for malignancies such as breast cancer and renal cell carcinoma. Efforts to develop a focal therapy approach for prostate cancer have been challenged by several concepts including the multifocal nature of the disease and limited capability of prostate ultrasound and systematic biopsy to reliably localize the site(s) and aggressiveness of disease...

BACKGROUND: The role of thoracic paravertebral blockade (TPVB) in decreasing opioid requirements in breast cancer surgery is well documented, and there is mounting evidence that this may improve survival and reduce the rate of malignancy recurrence following cancer-related mastectomy. We compared the two techniques currently in use at our institution, the anatomic landmark-guided (ALG) multilevel versus an ultrasound-guided (USG) single injection, to determine an optimal technique. METHODS: We retrospectively reviewed records of patients who received TPVB from January 2013 to December 2014...

High-intensity focused ultrasound (HIFU) is widely applied to tumors in clinical practice due to its minimally invasive approach. However, several issues lower therapeutic efficiency in some cases. Many synergists such as microbubbles and perfluorocarbon nanoparticles have recently been used to improve HIFU treatment efficiency, but none were determined to be effective and safe in vivo. In this study, nanoscale bubble-generating liposomes (liposomes containing ammonium bicarbonate [Lip-ABC]) were prepared by film hydration followed by sequential extrusion...

BACKGROUND: Ultrasound-guided wire localisation is a technique that is well established in breast surgery, but is not well described in head and neck practice. It can be used to locate impalpable lesions for surgical removal, without the need for more extensive surgery. METHOD: This paper describes a case where the technique was used to assist in the removal of an impalpable but radiologically abnormal lymph node. CONCLUSION: The technique offers a safe and effective method for removing lesions within the head and neck...

INTRODUCTION: Radiological measures to diagnose breast cancer, including mammographic and ultrasound assessments in young women, are associated with restrictions affecting the use of this tool. No adequate information is available on mammography view in young people with breast cancer and its relationship with pathologic type and epidermal growth factor receptor 2 (HER2) as a prognostic marker, especially in the Iranian race. This study was conducted to examine the relationship between mammographic findings of young women with breast cancer with diagnosed histopathologic type and HER2 marker status...

The aim of our study was to find effective features of mammography and ultrasound in differentiating Basal-like breast cancer (BBC) and Normal-like breast cancer (NBC), two subtypes of triple negative breast cancer (TNBC). From January 2014 to March 2017, we retrospectively reviewed 91 patients who were pathologically confirmed as TNBC. According to immunohistochemical cytokeratin 5/6 (CK5/6) and Epidermal Growth Factor Receptor (EGFR), TNBCs were classified into BBCs group and NBCs group. Both CK5/6 and EGFR were negative defined to be NBC, whereas if any of CK5/6 or EGFR was positive then defined as BBC...

Primary osteosarcomas of the breast are extremely uncommon. Here we describe a case of a 77-year-old woman who presented with a hard mass on her right breast. Mammography and breast ultrasound demonstrated a round-shaped calcified mass on the right breast but the features were not definitely diagnostic. For diagnostic purposes, an excisional biopsy was performed and the mass proved to be a primary osteosarcoma of the breast by pathologic findings. PET-CT and whole body bone scan showed neither evidence of metastasis nor underlying bone lesions...

INTRODUCTION: Ultrasound (US) is the imaging modality of choice for staging the axilla prior to surgery in patients with breast cancer (BC). High pathological complete response rates in the axilla after NACT mean a more conservative approach to surgery can be considered. Radiological re-staging is important in this decision making. After the presentation of results from ACOSOG Z1071 in December 2012, formal ultrasound re-assessment of the axilla after primary therapy was specifically requested in our institution...

Metastasis to the breast from an extra-mammary malignancy has been documented in literature, however cervical cancer metastasis to the breast is very rare. Thirty-eight cases of metastatic deposit to the breast from cervical cancer have been reported in literature. Though most patients present with a breast lump, it is very difficult to clinically distinguish a primary breast malignancy from a metastatic deposit. Histopathology of the tissue, aided with immune-histochemical staining pattern provides a definitive diagnosis...

The purpose of this study was to present a novel surgical method for intraoperative precise sentinel lymph node biopsy (SLNB) and to determine its clinical efficacy and sensitivity in breast cancer patients. The sentinel lymph nodes (SLNs) were preoperatively evaluated by axillary ultrasound. The intraoperative detection of SLNs was guided by lymphatic drainage pathway. The lymphatic vessels and SLNs were visualized. During operation, we searched for all the true SLNs (trSLNs), para-SLNs (paSLNs) and post-SLNs (poSLNs) followed lymphatic drainage ducts...

INTRODUCTION: Although pathology services focused on fine needle aspiration (FNA) biopsy of superficial palpable masses with on-site cytological evaluation are available in a wide range of clinical and academic settings, the addition of ultrasound (US) guidance into FNA practice by a cytopathologist group can be challenging. An US-FNA service provided by a cytopathologist in the department of Pathology is a relatively new practice in the field of medicine. This report summarizes our experience and strategies in achieving this objective and our successful preliminary results...
