“A recent survey of patients who went to the ER with belly complaints found that those who received extensive testing—including CT scans and blood work—were more likely to feel confident with their care than those who didn’t. More worrisome, over 70% of the same sample vastly underestimated the risk of the cumulative radiation exposure for the CT scans, and many of them did not recall accurately if they had ever received this test before.”

Zachary F. Maisel, MD, as quoted in the Time magazine article “Why Belly Pain Is Such a Headache for ER Doctors”

Editor’s E-Note

Performing deep-brain stimulation surgery in an MRI suite allows real-time image-guided treatment of patients with Parkinson’s disease. In its early cases, a new surgical system has allowed surgeons to place electrodes within 0.5 mm of their intended targets. Such accuracy is pretty important when the goal is implanting electrodes deep into the human brain. Read about it in this month’s E-News Exclusive.

MRI-Guidance Brings New Precision to Parkinson’s Treatment

An MRI-guided surgical technique developed at the University of California at San Francisco (UCSF) Medical Center may bring new precision to deep-brain stimulation surgery used to treat patients with Parkinson’s disease and other motion disorders.

Neurosurgeons at UCSF have been using deep-brain stimulation for more than a decade to reduce involuntary movements and improve mobility in patients with Parkinson’s disease. The procedure involves implanting a battery-operated brain stimulator electrode into movement-controlling structures in the brain. The stimulator overrides abnormal electrical patterns in those structures to reduce involuntary movement.
