Twice-a-year MRI more effective than mammograms for women with genetic breast cancer risk

Getting magnetic resonance imaging scans twice a year instead of one annual mammogram is far more effective at detecting early breast cancers in young women with a high-risk genetic profile than mammograms alone, according to a research team based at the University of Chicago Medicine and the University of Washington, Seattle.

			Preclinical Brain Imaging: The use of dMRI The use of magnetic resonance imaging (MRI) with diffusion-based strategies (dMRI) may be helpful for understanding neuronal connectivity, mainly via estimation and direct examination of specific water patterns into living tissue.

			Radical radiotherapy that reduces treatment to just 5 days could benefit men with prostate cancer Early results from an innovative new clinical trial led by researchers from Queen's University Belfast have shown that men with prostate cancer could benefit from radical radiotherapy that delivers treatment in just five visits instead of the usual 37.

	Researchers develop and test new MRI coil for preclinical studies Researchers from ITMO University developed and tested an MRI coil providing high-resolution imaging of the whole body of a mouse.

	Radiation therapy impairs new memory formation in pediatric brain tumor patients Young people who received radiation therapy for the most common pediatric brain tumor struggle to create new memories about specific events, according to a study of children and adolescents published in JNeurosci. Their ability to recall events prior to treatment, however, remains intact.

	New nuclear medicine imaging method could help diagnose widespread tumors A new nuclear medicine imaging method could help diagnose widespread tumors, such as breast, colon, pancreas, lung and head and neck cancer better than current methods, with less inconvenience to patients and with equal or improved accuracy.

	Integrated PET/MR for Alzheimer’s Disease PET/MR imaging is used for monitoring and assessing brain function, molecular information and metabolism. Combined PET/MR imaging has improved the diagnostic power for Alzheimer’s disease, enabling early and accurate diagnoses and better elimination of differential diagnoses. Combining PET and MR scans is a convenient option for patients which also lowers the amount of radiation they are exposed to.

	A non-canonical approach may improve radiation treatment for cancer Although the success or failure of radiation therapy for cancer has long been associated with the intrinsic radio-resistance or radio-sensitivity of tumor cells, a new approach is demonstrating that radiation can take credit for an additional benefit -; causing highly effective secondary immune responses that can enhance anti-tumor immunity.

	New study describes effect of radiation exposure on hormone deficiency in children In a new study, University of Cincinnati researchers, in collaboration with Massachusetts General Hospital, have detailed the effect of radiation exposure on the development of hormone deficiency in pediatric and young adult patients treated for brain tumors.

	Targeting pathway controlling mitochondria may reduce cancer invasiveness Targeting a pathway that controls the movement of mitochondria, the powerhouses of all cells, could reduce cancer invasiveness and resistance to radiotherapy.
