Brain scans are not as accurate as one might think. Most or all methods merely show activation of neurons or groups of neurons over a timescale.
Typically you give a person, say a memory task, you look at which areas fire up as he tries to memorise a word list and from that you extrapolate whatever you can from it.
I also believe working memory and short term memory are to some extent better understood than long term memory. actually the least known process regarding memory I think is how memories pass from working memory or short term memory into long term memory.

I'm not sure if the scan is inaccurate or the representation within the brain, but I suppose it had to be more accurate than just a fuzzy area.
