CT Scan

In an earlier post, I mentioned that even at this late stage of my career, I still occasionally stand in awe of our ability to see inside the human body. This usually occurs when I'm scrolling through images from a CT of the chest done to rule out blood clots to the lungs. 95+ percent of these studies do not show blood clots. Often they are entirely normal, and sometimes they show other pathology. It's easy to become cynical about this overused test. Still, it can be a thing of beauty to see the branching of the pulmonary arteries. Click on the play button to see a very brief movie.
