Both MRIs and CT scans are used to create pictures of your organs to help doctors discover and diagnose potentials issues. The main difference between these two sophisticated imaging techniques is that CT (computed tomography) scans use X-rays while MRIs (magnetic resonance imaging) use radio waves. Both of them create detailed images of inner tissues
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
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
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
Healthy adults who consumed energy drinks high in caffeine and taurine had significantly increased heart contraction rates one hour later, according to a study presented at RSNA 2013. “Until now, we haven’t known exactly what effect these energy drinks have on the function of the heart,” said radiology resident Jonas Dörner, MD, of the cardiovascular
Experts from both the Fraunhofer Institute for Biomedical Engineering IBMT in St Ingbert, Germany, and the Fraunhofer Institute for Medical Image Computing MEVIS in Bremen, Germany, are working together on the MARIUS (magnetic resonance imaging using ultrasound) project, developing a quicker, gentler, more cost-effective biopsy method that is easier on breast cancer patients. The new
The American Headache Society (AHS) recently released a list of specific tests or procedures that are commonly performed but not always necessary in the treatment of migraines and headaches. The list was developed as part of Choosing Wisely, an initiative of the ABIM Foundation. The AHS list identifies five targeted, evidence-based recommendations that can support
Radiology Today, a professional publication, just published an interview with Carol H. Lee, MD, FACR, and chair of the American College of Radiology’s Communications Committee of the Breast Imaging Commission and past president of the Society of Breast Imaging. Radiology Today (RT): Dense breast tissue notification laws are on the books in 13 states. With
According to Medical News Today, the American Academy of Orthopaedic Surgeons 2013 annual meeting reviewed a new study which shows that MRI scans can help reduce further pain and tissue damage for total hip replacement patients. Apparently MRI scans are highly sensitive to tissue changes in failing or at risk Metal-on-Metal hip replacement patients. This
