Nonscreened Patients With Breast Cancer Need More Treatment Than Screened Patients Screening women aged 40 to 49 for breast cancer has additional benefits beyond the proven decrease in mortality rate, according to researchers at Case Western Reserve University. Patients screened with mammography are statistically less likely to undergo chemotherapy, avoiding the associated toxic morbidities. Screening
PET is a promising tool for determining which severely brain-damaged individuals in a vegetative state could potentially recover consciousness, according to new research published in The Lancet. It’s the first time that researchers have tested the diagnostic accuracy of functional brain imaging techniques in clinical practice. “Our findings suggest that PET imaging can reveal cognitive
Quantitative plaque analysis using cardiac CT angiography (CCTA) provides an accurate assessment of arterial plaque and could dramatically impact the management of patients with diabetes who face a high risk of heart attacks and other cardiovascular events, according to new research. Plaque that forms in the arterial walls can restrict blood flow and, in some
Liver cancer survival rates could be improved if more people with cirrhosis are screened for tumors using ultrasound scans and blood tests, according to a review published in PLOS Medicine by physicians at UT Southwestern Medical Center in Dallas. The meta-analysis of 47 studies involving more than 15,000 patients found that the three-year survival rate
When cancer progresses and spreads to the bone, patients often suffer debilitating pain. A new phase III clinical trial shows that noninvasive MR-guided focused ultrasound (MRgFUS) treatment that heats the cancer within the bone relieves pain and improves function for most patients when other treatment options are limited. The results were published in the Journal
Unlike healthy cells, cancer cells thrive when deprived of oxygen. Tumors in low-oxygen environments tend to be more resistant to therapy and spread more aggressively to other parts of the body. Measuring tumors’ oxygen levels could help physicians make decisions about treatments, but there’s currently no reliable, noninvasive way to make such measurements. However, a
Image Gently’s New DR Checklist May Also Aid Exam Data Collection By David Yeager DR has brought many improvements to the way that X-ray images are captured and processed, but it has created new challenges as well. Although DR has increased the efficiency of obtaining, storing, and retrieving images and reduced the number of repeat
Keith Hentel, MD, likes to tell this story: A young boy fell out of a third-story window and was taken to NewYork-Presbyterian Hospital/ Weill Cornell Medical Center’s emergency department for treatment. Hentel was the radiologist on call. The emergency physicians wanted a CT scan to determine whether the child had internal injuries. The child’s parents
Researchers have used radioimmunotherapy (RIT) to destroy remaining HIV-infected cells in the blood samples of patients treated with antiretroviral therapy. The approach could provide a strategy for curing HIV infection, according to research presented at RSNA 2013. Highly active antiretroviral therapy (HAART) has transformed the outlook for patients infected with HIV by suppressing the replication
Automated breast density measurement predicts breast cancer risk in younger women, and that risk may be related to the rate at which breast density changes in some women as they age, according to research presented at RSNA 2013. Breast density, as determined by mammography, already is known to be a strong and independent risk factor
