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 Massachusetts Institute of Technology (MIT) …

Lung cancer is the leading cause of cancer deaths in the United States and has a particularly poor prognosis if not diagnosed early. Prompt follow-up on incidental findings from CT scans ordered for other reasons may find more cancers earlier, but a study published in the April issue of the Journal of the American College of Radiology (2014;11(4):378-383) reported that …

New Research Shows Promise for Possible HIV Cure


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 of the virus in the …

Breast Density Measurement May Predict Cancer Risk

Breast Density

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 for breast cancer. The American …

MRgFUS Offers Noninvasive Treatment for Breast Cancer


Focused ultrasound under MR guidance may offer a safe and effective noninvasive treatment for breast cancer, according to research presented at RSNA 2013. MR-guided focused ultrasound (MRgFUS) ablation requires no incision or puncture to perform. Instead, it uses the acoustic energy from high-intensity focused ultrasound to heat and ablate diseased tissue. Continuous MRI is used to locate the lesions and …

MRI Shows Long-Term Impact of Veterans’ Blast-Induced Brain Injuries

Veterans Blast Induced Brain Injuries

Using a special type of MRI, researchers have found that soldiers who suffered mild traumatic brain injury (MTBI) induced by blast exposure exhibit long-term brain differences, according to a study presented at RSNA 2013. Recent wars have resulted in veterans with an exposure rate of approximately 20% to blast-induced MTBI, or trauma resulting from mortar fire and improvised explosive devices. …
