Hello, I'm LM2000. I noticed that you recently removed some content from Positron emission tomography without explaining why. In the future, it would be helpful to others if you described your changes to Wikipedia with an accurate edit summary. If this was a mistake, don't worry: I restored the removed content. If you would like to experiment, please use the sandbox. If you think I made a mistake, or if you have any questions, you can leave me a message on my talk page. Thanks!
