Can't remember the location of the tricuspid valve? Need to know what an aortic aneurysm looks like on an echocardiogram? Click over to Introduction to Cardiothoracic Imaging from Yale University School of Medicine. Although aimed at medical students, the beautifully illustrated tutorial is a good resource for researchers or anyone else who wants to pump up their knowledge of heart and lung anatomy. Other sections use x-rays, echocardiogram footage, and other media to show how the structures change as a result of diseases such as emphysema and mitral stenosis, a narrowing of the opening between the left atrium and ventricle that can allow blood backflow. You'll also find a rundown of various imaging techniques.
