In this month's technology section in our print edition, you can read about how MRI technology can be used during surgery. For patients with tumors, this technology can be a godsend, enabling surgeons to get a real-time picture during a difficult procedure.

After interviewing experts at Mayo Clinic, Cleveland Clinic and Cook Children's Health Care System, I was inspired. What a tribute to human ingenuity. It left me wondering: How else can MRI advance the cause of medicine?
