NCAC-SOT Fall Symposium

The goal of this symposium is to introduce and discuss noninvasive techniques that may have application to a number of toxicological endpoints. Toxicology has progressed in no small measure by incorporating/adopting procedures from other biological and sometimes physical sciences. Some in the scientific community think imaging technologies hold great promise to increase our ability to study physiological processes and in particular how those processes are disturbed by various chemicals. These techniques run the gamut from magnetic resonance imaging, ultrasound, computer-assisted tomography to positron emission tomography. Each more than likely can make some contribution to advancing toxicology, but the question is how. Each has its own advantages and disadvantages as well. What are those and how can the advantages best be utilized? There are certain practical benefits of using this new technology none the least of which is use of fewer animals and it would more than likely allow toxicologists to better interpret physiological data. A thorough discussion of these techniques between those who are developing and those who would use them is needed. It is hoped this symposium will help bring this about and allow for a better determination of how and when these techniques can be expected to contribute in significant fashion to toxicology.
