The applications of CT continue to unfold and in the process save lives. Scientists are now using scans to study the development of insects in the place of dissection which is time consuming and kills the specimens. Think of how many tiny lives could be saved. Insects make up between 50% and 85% of the animals on this planet, but not much is ...

Since many people don’t know the difference between CT and MRI, I was wondering if patients who get a CT even know about the radiation risks. I found a study that addresses this issue. A large medical center surveyed 235 patients who underwent either a CT or PET-CT. Researchers found that one third of patients receiving scans did not realize ...

The Centers for Medicare and Medicaid Services has been researching hospitals that order too many CT scans. They particularly looked at the ordering of “double scans” or two scans ordered for the same patient; one with a contrast agent and the other without. “Such double scans are rarely necessary, and expose patients to 700 times as much ...

Veterinary diagnostic imaging has sure come a long way, baby.

I continue to be intrigued by stories that discuss CT scans on unusual subjects. The most recent article I read talks about the dental and sinus health of a young man who was mummified and lived about 2,100 years ago in Egypt. “He had numerous abscesses and cavities, conditions that appear to have resulted, at some point, in a sinus ...

An unusual story came out of Richmond, VA this week. A woman who had a CT scan for abdominal pain with both PO and IV contrasts had an odd reaction. She claims the palms of her hands and the soles of her feet turned orange and became very dry about 15-20 minutes after the scan.Several days after the scan she went back to the hospital for some ...

It is with great anticipation that many Americans welcome opening day of the 2012 NFL Season. With all of the fun that comes with tailgates and parties, the health of these athletes must not be overlooked. The American Academy of Neurology just released a study that confirms previously held beliefs “… that head injuries cause neurologic ...

We all know about the dangers of radiation from CT scans but what about the radiation that is emitted from our cell phones. Many of us have our phones on us at all times and we feel as if we can’t live without them. What if they are causing us more harm than good. Previous studies have shown that there is such a small amount of radiation ...

The May/June 2012 CT Edition of the Journal of the American Society of Radiologic Technologists has an excellent article about stroke and CT perfusion. The information outlined is invaluable to any technologist who has to perform perfusion scans. When they started doing them at my former hospital I received very little training on how to ...
