According to the National Cancer Institute estimates, each year approximately 192 000 women are diagnosed with breast cancer. Imaging studies are used to establish any abnormality in the breast, with mammography as the mainstay of screening for breast cancer. Ultrasonography, computerized tomography, magnetic resonance imaging, and nuclear medicine procedures also have become an important aid in the identification of abnormalities in the breast tissues. This article will examine the anatomy of the breast, provide a detailed account of malignant pathology arising in the breast tissues, discuss the role of imaging in detecting these abnormalities, and outline treatment modalities for breast cancer.
Lower extremity venous insufficiency is a potentially debilitating condition that can negatively affect an individual's quality of life. There are several risk factors associated with the development of venous insufficiency symptoms. If these symptoms are left untreated, early venous insufficiency symptoms can continue to worsen until chronic venous insufficiency develops. This article provides a brief overview of venous anatomy, physiology, and pathology; a description of the CEAP system, a universal scoring system developed by the American Venous Forum; and an explanation of the most common imaging methods used to diagnose venous insufficiency.
Computed tomography (CT) and magnetic resonance imaging (MRI) are 2 valuable modalities in imaging studies of the abdomen and pelvis, and radiologic technologists should be familiar with proper patient preparation, examination setup, examination parameters, and possible findings in clinical applications of CT and MRI. Through a series of case studies, this article will address techniques used to perform imaging studies in patients presenting with problems as varied as chronic kidney disease, kidney disease of unknown etiology, abdominal abscess, lymphoma, abdominal aortic aneurysm, liver hemangioma, and traumatic pelvic injury.
Magnetic resonance imaging (MRI) continues to show improvement in the detection and diagnosis of breast cancer, even in its earliest stages. It is especially beneficial for imaging lesions that are occult on other modalities. To better understand the role of MRI in conventional breast imaging and as a modality for guiding biopsies this article provides a review of basic MR breast imaging techniques, an overview for technologists of MRI-guided stereotactic breast biopsy procedures, and highlights the pros and cons of MRI breast biopsy guidance as an alternative to surgical biopsy. The role of the MRI technologist, various safety considerations, and technical developments are also discussed.

In a prospective trial to test the feasibility of laparoscopic high-intensity focused ultrasound ablation of uterine localized adenomyosis, Chinese researchers found the procedure to be a safe and effective procedure.
Data from a preclinical study presented at the Society of Nuclear Medicine 56th Annual Meeting suggest that α therapy, in association with fast-clearing peptides, can be effective in treating prostate cancer.
The application of a skin patch that delivers radiotherapy can be an effective alternative to surgery to treat skin cancer, according to data presented at the Society of Nuclear Medicine 56th Annual Meeting.
Fluorodeoxyglucose-positron emission tomography/computed tomography can provide a more precise assessment of recurrence and outcome in ovarian cancer than the standard serum tumor marker, a study presented at the Society of Nuclear Medicine 56th Annual Meeting has found.
