MRI podcast and info

This podcast is part of an NPR blog/podcast that I follow called Planet Money. This podcast is super interesting as it follows MRI prices around the world. This seemed relevant as the health care debate rages on. MRI's are expensive in Alaska, but what is early detection worth? My local Internal Medicine Doctor, Dr. Mcdonagh seems to favor less imaging/xrays as studies in the UK have shown that up to .6% of cancers are caused by medical x-rays. I tend to favor his line of thought, letting blood work and the age old method of poking and prodding reveal a diagnosis. Check out the podcast HERE
