The year is about to come to a close. There will be a lot of new preventive imaging news in 2008 but let's take a look back at the important stories of 2007. Here are some of the favorities: - Starting in January, there was important news about a new virtual colonsocopy procedure that has the potential to be life-saving. Later in the year we saw technological developments in another area of imaging: the 3D brain scan. - Stories about the importance of heart health screenings have been important all throughout the year. Some examples of these include information on how heart screens save both lives and money, true stories about people saved by heart screens, and news about how lung scans could be important for heart patients. - In news that's a little bit more on the fun side, a favorite story was the one about how MRIs might be able to be used as lie detector tests. And in related news that's a little more serious, we learned that MRIs might be able to provide us some insight into the minds of pedophiles. Those are just a few of the interesting stories that took place throughout the year. (You can check our archives for others.) Now it's time to get ready for news in 2008!
