Scandinavian studies take mammography to task once again
Two new papers in the British Medical Journal served up backhanded compliments to mammography. The first acknowledged that breast cancer screening does reduce overall mortality, but noted that it still carries a 10% rate of overdiagnosis. The second study suggested that as noble as public screening programs may be, women are dangerously misinformed as to the benefits and drawbacks of participation.

Carefully considered radiotherapy stymies endometrial cancer relapse
Endometrial cancer is the fourth most common cancer in women. The treatment regimen can include radiation therapy, but its use is fairly recent, and not without some controversy. However, two recent studies, one by researchers in the Netherlands and the other from a group in Utah, both found that radiation therapy reduces the rate of locoregional recurrence, but without an overall survival benefit.

MRI makes connection between diabetes, CNS
The brain has not traditionally been considered a target for diabetic complications, but new research has shown that the disease does affect the central nervous system (CNS). The underlying causes, however, are poorly understood. This led researchers from New York to use MRI to study the effects of diabetes on the CNS and cerebrovascular volume (CBV).

Experts' reactions to AHRQ breast imaging report range from 'ho hum' to 'dangerous'
A recent Agency for Healthcare Research and Quality (AHRQ) report stated that alternative breast imaging modalities were not a viable alternative to breast biopsy. The report had the potential to stir up serious trouble, but given the controversy that generally permeates breast cancer screening, the report's conclusions seemed to have landed with a particular thud among breast imaging experts.

Dual-energy subtraction x-ray offers powerful tool for depicting thoracic abnormalities
Dual-energy subtraction chest x-ray edges out conventional imaging because of its ability to detect calcification within a pulmonary nodule. But this technique has its limitations, according to a group from the University of Wisconsin Medical School, Hospital and Clinics in Madison.

APBI variables affect late tissue toxicity, cosmetic outcome
Accelerated partial-breast irradiation (APBI) combines high radiation doses, and a shorter treatment period, with one of four delivery methods including interstitial brachytherapy or intraoperative radiation therapy. But little is known about the associated delayed tissue toxicity. A new study details how APBI-related variables can influence tissue toxicity and cosmetic outcome.

Larger lesions on breast MRI equal greater chance of cancer
The likelihood of malignancy in MRI-detected breast lesions increases with lesion size, according to a study in the American Journal of Roentgenology. As a result, the authors suggested that biopsy may not always be necessary for lesions smaller than 5 mm.

US in the ICU: An essential tool in critical care treatment
Ultrasound is as indispensable in the intensive care unit (ICU) as the bedside nurse, according to a critical care specialist. In several presentations at the 2006 Society of Critical Care Medicine (SCCM) meeting in San Francisco, ICU doctors offered examples of how they make the most of sonography in their field.

CT more sensitive than spinal fracture x-ray, but has limits
Patients with blunt trauma are at a high risk for thoracolumbar spine fractures, which require swift evaluation. Spinal x-ray is commonly used in these situations, but it is a time-consuming and difficult exam. So a group of surgeons and radiologists investigated whether CT might be a viable alternative.
