What is a lot of snow? As the northeast just experienced a snow storm, there are many opinions about whether or not it was a lot. Those who live in New Jersey may think 1 foot is average, while those in upstate New York think that’s a light amount. And there is no meteorological standard to define “a lot”; just public opinion.
When you look at medical imaging, the question currently being asked is: what is “low dose”? Is a chest CT scan at 4 mSv low dose? It is lower than today’s standard, but does it qualify as “low dose”? Quite surprisingly, while the topic of low dose CT has been played out for years now, the definition - which is quite necessary when it comes to radiation dose – has often remained undefined.
