Fast Field Cycling Magnetic Resonance Imaging (FFC-MRI) is an emerging technique that allows getting images at different magnetic field intensities [1-3]. Furthermore, it is possible to perform images at low magnetic fields (from earth magnetic field or less until several hundreds of mT). These abilities make possible to maximize the contrast by T1 for heterogeneous samples. For example, the T1 contrast between gray and white matter is maximized at 0.25 T [4]. In addition, FFC-MRI is a versatile technique which is ideal to explore new types of contrast and possibilities as double resonance [5], temperature maps and others. In this work we present the performance of a homemade FFC MRI-relaxometer system [6]. This includes images in biological samples and maps of temperature.
