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, ...

BACKGROUND We presented the photoacoustic imaging (PAI) tool and to evaluate whether microcalcifications in breast tissue can be detected on photoacoustic (PA) images. METHODS We collected 21 cores containing microcalcifications (n = 11, microcalcification group) and none (n = 10, control group) in stereotactic or ultrasound (US) guided 8-gauge vacuum-assisted biopsies. Photoacoustic (PA) ima...

A method has been developed to detect and analyse microcalcifications in digitized mammographic images. The algorithms presented in this work combine an image preprocessing to denoise the digital image and image treatment techniques to localize and characterize the features of the microcalcifications. Two image denoising methods have been applied to the mammographies, the first one is an adapti...

The aim of this study was to describe the potential 18F-sodium fluoride (18F-NaF) positron emission tomography (PET) identify graft vasculopathy and investigate influence coronary artery bypass (CABG) surgery on native disease activity progression.As well as developing vasculopathy, CABGs have been proposed accelerate atherosclerosis.Patients with established underwent baseline 18F-NaF PET, cal...

An algorithm was developed in this study, using rule-based fuzzy logic, to enable masses that are hard to recognize or detect in mammograms to become more readily perceptible. Small lesions, such as microcalcifications and other masses that are hard to recognize, especially on film scan mammograms, were processed through segmentation. A total of 40 mammograms were used and they were classified ...

Radiologically guided localization procedures are indicated pre-operatively when breast lesions are nonpalpable. The results of 42 percutaneous hookwire localizations over a period of 3 years are described. Of the total, 7 (17%) were found to be malignant. Biopsy was indicated by mammographically detected mass in 48%, by microcalcifications in 40% and by microcalcifications with an associated m...

Atherosclerotic burden has become the focus of cardiovascular risk assessment. PET/computed tomography (CT) imaging with tracers 18F-fluorodeoxyglucose and 18F-sodium fluoride shows arterial wall inflammation microcalcification, respectively. Arterial uptake both is modestly age dependent. consistently associated factors more easily measured in heart. Because extremely high sensitivity, ultrash...
