For now, MBI use is limited to research. The focus is to reduce the dose of radiation needed to perform MBI. The risk from the radiation dose of one or two MBI scans is extremely low. But to safely use MBI annually or every few years, the radiation dose needs to be reduced.

"Our goal is to have a dose that's no higher than that from a routine mammogram," says Dr. Rhodes. "If we get results that are similar to, or better than, our last study, we'll be well on our way to supporting MBI as an option for women with dense breast tissue."

Canes, Walkers: These Tools Are Made for Walking

ROCHESTER, Minn. -- When walking is difficult because of arthritis, balance problems, pain or injury, don't avoid a cane or walker because they are dreaded symbols of old age. Instead, consider the devices as a way to help avoid injury and maintain independence.

The March issue of Mayo Clinic Women's HealthSource offers tips for selecting and using canes and walkers:

Canes: Canes provide balance and support for walking, handling up to 25 percent of their body weight. Many types of canes are available. Aluminum ones are adjustable; wooden canes must be cut to fit. For everyday use, a hooked, or candy cane-style, cane probably won't be the most comfortable. A swan neck handle, which is flatter and puts the user's weight directly over the cane's shaft, likely will feel better.

For appropriate fit, the top of the cane should reach the crease of the wrist when the user is standing up straight with arms hanging comfortably. Using a cane that's too long puts strain on the arms, shoulders and back muscles. Too short, a cane throws off balance.
