www.nuclmed.gr To the Editor: With interest we read the paper by Özülker et al (2010) [1]. For more than 15 years, scintimammography has been tested against mammography, ultrasound and MRI of the breast. Scintimammography has repeatedly shown high specificity for breast lesions. Although sensitivity rates are also favorable, scintimammography is less useful in non-palpable tumors [2]. The above...

BACKGROUND Breast cancer is one of the most common cancers and the first-leading cause of cancer deaths among women in the world. Indeed, breast cancer is ranked as the first malignancy among Iranian women. Breast density, defined as the percentage of fibro glandular breast tissue in mammographic images, is one of the known risk factors for breast cancer. According to American college of radiol...

Triple-negative (TN) breast cancers were defined as those which tested negative for estrogen receptor (ER), progesterone receptor (PR), and HER2. TN breast cancers account for 12%– 26% of all types of breast cancers [1–5]. TN tumors were aggressive and were usually diagnosed at a later stage [5]. About 85% of TN phenotypic breast cancers are deemed to be basal like and have a clinical behavior ...

Physicians in Egypt and other Arab and developing countries still have to deal on a daily basis with large numbers of patients with advanced stages of breast cancer at presentation. Efforts at measuring the magnitude of the breast cancer issues, epidemiology, and awareness, are now moving further in the right direction. We are now starting to face the challenges of early detection of breast can...

INTRODUCTION Recent results suggest that quantitative analyses of Dynamic-Contrast-Enhanced (DCE) MRI pharmacokinetic data using the Shutter-Speed Model (SSM) can yield very high breast cancer screening specificity [1]. The SSM differs from the Standard Model (SM) normally used for DCE-MRI only by allowing that equilibrium intercompartmental water exchange processes can have finite kinetics [1,...
