[Details of a magnetic resonance system (SIS 200/400) for experimental small animals].

Magnetic resonance imaging (MRI) and magnetic resonance spectroscopy (MRS) employing the nuclear magnetic resonance (NMR) phenomenon were used as a non-invasive method for obtaining anatomical images and for studying intracellular metabolism in vivo. A SISCO SIS 200/400 MRI/MRS experimental system for small animals (4.7 tesla, 400 mm bore) was set up, and its installation was completed in October 1993. The system makes it possible to obtain excellent quality animal images and to analyze a cellular metabolism in vivo. We introduce the details of our particular system, computers, data processing and image resolution together with examples of rat and puppy images.
