Purpose Image‐guided needle biopsy of small, detectable lesions is crucial for early‐stage diagnosis, treatment planning, and management breast cancer. High‐resolution positron emission mammography (PEM) a dedicated functional imaging modality that can detect cancer independent tissue density, but anatomical context real‐time visualization are not yet available to guide biopsy. We propose mecha...

Introduction:MAMMI is a dedicated PET based on high resolution detectors placed close to the breast. In this study, we presented a GATE model for the simulation of MAMMI scanner and model its performance of the MAMMI based on an adaptation of the NU 4-2008 NEMA standard.  Methods:A detailed of geometry MAMMI system that uses scintillation crystals coupled...

In this article, we trace the chronology of developments in breast imaging technologies that are used for diagnosis and staging of breast cancer, including mammography, ultrasonography, magnetic resonance imaging, computed tomography, and positron emission tomography. We explore factors that affected clinical acceptance and utilization of these technologies from discovery to clinical use, inclu...

• Vol 8 • December 2006 838 Diabetic mastopathy is an uncommon benign histopathologic condition manifested by a palpable mass. It typically occurs in premenopausal women with longstanding early-onset insulin-dependent diabetes mellitus and microvascular complications. It was first reported in 1984 by Soler and Khardori [1] in a series of 12 patients. Since then, over 200 cases have been describ...

A prototype for positron emission mammography is under development within a collaboration of the Italian Universities of Pisa, Ferrara, Bologna and Roma. The device is composed of two stationary detection heads, each with an active area of 6 cm × 6 cm, made of 30×30 YAP:Ce finger crystals of 2 mm × 2 mm × 30 mm. The EGSnrc Monte Carlo code has been used to perform a complete simulation of this ...

Breast plasmacytoma is an extremely rare tumor. It can occur as a primary isolated tumor or as an extramedullary manifestation in multiple myeloma. This report describes the unusual case of a primary extramedullary plasmacytoma that progressed to multiple myeloma within 15 months in a 35-year-old woman. The patient had been initially diagnosed with a primary extramedullary plasmacytoma of the e...

Optical breast imaging offers the possibility of noninvasive, low cost, and high sensitivity imaging of breast cancers. Poor spatial resolution and a lack of anatomical landmarks in optical images of the breast make interpretation difficult and motivate registration and fusion of these data with subsequent optical images and other breast imaging modalities. Methods used for registration and fus...

OBJECTIVE To evaluate the impact of 18F-fluoro-deoxy-glucose positron emission tomography after standard diagnostic workup in patients with advanced head and neck squamous cell carcinoma on staging and radiation treatment planning. STUDY DESIGN Prospective controlled study. METHODS Forty-eight patients (42 men and 6 women; mean age, 61 y; age range, 35-85 y) with histologically confirmed, a...

PURPOSE The use of 18F-2-deoxy-2-fluoro-D-glucose positron emission tomography-computed tomography as a routine preoperative modality is increasing for gastric cancer despite controversy with its usefulness in preoperative staging. In this study we aimed to determine the usefulness of preoperative positron emission tomography-computed tomography scans for staging of gastric cancer. MATERIALS ...
