BACKGROUND Breast cancer is the most common type of cancer in women worldwide. Mammography is considered the "gold standard" in the evaluation of the breast from an imaging perspective. Apart from mammography, ultrasound examination and magnetic resonance imaging are being offered as adjuncts to the preoperative workup. Recently, other new modalities like positron emission tomography, 99mTc-ses...

We sought to prospectively assess the diagnostic performance of a high-resolution positron emission tomography (PET) scanner using mild breast compression (positron emission mammography [PEM]). Data were collected on concomitant medical conditions to assess potential confounding factors. At four centers, 94 consecutive women with known breast cancer or suspicious breast lesions received 18F-flu...

Breast cancer is one of the most common cancers among the population of the Western world. Diagnostic methods include mammography, ultrasound, and magnetic resonance; meanwhile, nuclear medicine techniques have a secondary role, being useful in regional assessment and therapy followup. Optical imaging is a very promising imaging technique that uses near-infrared light to assess optical properti...

Malignant transformation of cells into cancer arises due to long term accumulation of genetic and epigenetic events. Early diagnosis of these transformations in cells can improve the prognosis of cancer cases. Cancer screening and surveillance methods include ultrasound, mammography, digital mammography, magnetic resonance imaging, computed tomography, positron emission tomography and magnetic ...

abstract necrotizing sarcoid granulomatosis (nsg) is a rare disease which is classified in the spectrum of pulmonary angiitis and granulomatosis. it is a variant of sarcoidosis and differs from it histologically. diagnosis is based on the pathological features, but radiology may help in the differential diagnosis. it is characterized by alveolar infiltrates or parenchymal nodules in multidetect...

A small breast cancer was detected by positron emission tomography (PET) in an asymptomatic individual. Physical examination, mammography and magnetic resonance imaging all failed to identify the tumor. Treatment was partial resection of the breast. Based on the resected specimen, the tumor was 6 mm in diameter. Although previous studies have shown PET to be highly sensitive for the detection o...

PURPOSE To compare radiation doses and lifetime attributable risks (LARs) of radiation-induced cancer incidence and mortality from breast imaging studies involving the use of ionizing radiation. MATERIALS AND METHODS Recent literature on radiation doses from radiologic procedures and organ doses from nuclear medicine procedures, along with Biologic Effects of Ionizing Radiation (BEIR) VII age...

The application of Positron Emission Tomography (PET) using 2-[F18] fluoro-2-deoxy-D-Glucose (FDG) and the more recently fused technique of Computerized Tomography and PET (PET/CT) in patients with breast cancer is reviewed. Their role in diagnosis of primary tumour, staging, chemotherapy monitoring and radiotherapy planning, follow-up and restaging is introduced. The advantages of combination ...

Images from dual detector positron emission mammography (PEM) systems are commonly reconstructed by backprojection methods of classical tomography. Characteristics of 3–D PEM images were investigated using analytic models and computer simulations, in particular depth resolution and the quality of images in the third dimension normal to the detectors. These modeling tools provide insight into th...
