i have had regular cat scans, once per year for the last 5 years or so for multiple nodules on my lungs. i just heard about how much more radiation is in a cat scan than an x ray after my last set last may. unfortunately im going to have more in the future because of the medical situation. i wouldnt if i didnt have to.

on a side note, does anyone else get headaches from mri's? ive had numerous mri's between pn testing and numerous herniated discs. ive been getting regular low level headaches the last few years after doing mri's. just wondering.
