We talk a lot about the different types of preventive imaging that are available and emerging in the medical field today. We also talk about the importance of getting screened for specific frightening diseases like colon cancer. However, sometimes it's important to just get back to the basics and to take a look at why the entire field of preventive imaging medicine is so important to society. The main reason, of course, is that preventive imaging allows for the early detection of disease. What this means is that people are able to find out early on if they have a disease that is developing in the body. The reason that this is important is because almost all diseases are easier to treat and cure when they are just starting out. As they grow, they become increasingly deadly, a problem which can be avoided with early detection of disease through preventive imaging. There are other reasons that preventive imaging is important, though. For example, the treatment of diseases - and sometimes their cure - depends heavily on the information that is provided to doctors through medical imaging. This isn't just useful to the individual patient but can also be used in research and in the development of better medical treatments and tools.
