OBJECTIVE. The purpose of this article is to review the use of MRI in breast density measurement and breast cancer risk estimation and to discuss the role of MRI as an alternative screening to mammography for screening women with dense breasts. ⋯ The potential of MRI for screening women with dense breasts remains controversial because of the paucity of clinical evidence, the possibility of overdiagnosis, and the cost-effectiveness of the technique in this population. Although methods of MRI measurement require standardization and automation, future addition of MRI density to risk models may positively impact their value.

Distal humeral epiphyseal separation in young children: an often-missed fracture-radiographic signs and ultrasound confirmatory diagnosis.
OBJECTIVE. Distal humeral epiphyseal separation is rare and often misdiagnosed. The purpose of this study was to summarize an experience with radiography and ultrasound of distal humeral epiphyseal separation. ⋯ CONCLUSION. The diagnosis of distal humeral epiphyseal separation is often missed on radiographs. Radiologists should be aware that posteromedial displacement of the radius and ulna in young children is highly suggestive of distal humeral epiphyseal separation and that the diagnosis can be confirmed with ultrasound.

ReviewAlternative screening for women with dense breasts: breast-specific gamma imaging (molecular breast imaging).
OBJECTIVE. Given mammography's limitations in evaluating dense breasts, examination with breast-specific gamma imaging (BSGI)-also called molecular breast imaging (MBI)-has been proposed. We review the literature pertinent to the performance of BSGI in patients with dense breasts. ⋯ Many studies have reported the sensitivity of BSGI in finding cancers even in dense breasts. However, BSGI has not yet been validated as an effective screening tool in large prospective studies. In addition, whole-body dose remains a significant concern.
