The purpose of this article is to review the ultrasound characteristics of ovarian and adnexal masses and to discuss the prediction of the likelihood of ovarian cancer based on these characteristics and clinical parameters. ⋯ Ultrasound characteristics can be used to diagnose the classic-appearing nonneoplastic entities, benign neoplasms and malignancies. In cases in which the appearance of an ovarian mass is not classic, assignment of relative risk of malignancy using a multiparametric model is appropriate and beneficial for patient management.

ReviewMRI findings in inflammatory muscle diseases and their noninflammatory mimics.
The purpose of this article is to provide a practical review of the spectrum of MRI findings in inflammatory muscle diseases and their noninflammatory mimics. ⋯ MRI is a highly sensitive tool for the diagnosis of muscle diseases. Although it has low specificity, awareness of the potential imaging findings in the various, sometimes rare, muscular disorders is helpful for accurate diagnosis.

We review the basics of functional renal imaging and highlight a few clinical applications. ⋯ Techniques such as contrast-enhanced MR renography, diffusion-weighted imaging, and blood oxygen level-dependent MRI have been investigated in animal models and in a few human studies. Functional renal imaging is a rapidly growing field that has the potential to provide new insight into the pathophysiology of renal disease.
