There are other important roles for preclinical imaging, however. One of these is the development of new clinical techniques. Yesterday, I read an interesting article describing a potentially new technique for treating cardiac arrhythmia. Micro CT images acquired byMark Riccio and company at Cornell, using an eXplore CT-120 played an important role in this research (check out the supplementary information and a summary article at Science/AAAS for some images). This is just one exciting example of the usefulness of preclinical imaging in the development of clinical treatments.
