Preclinical Magnetic Resonance Imaging (MRI) service

Ephoran Multi Imaging Solutions Preclinical Services is a contract research organization (CRO) located in the Bio Industry Park of Canavese at Colleretto Giacosa (Torino, Italy), offering preclinical MRI imaging services. In vivo preclinical imaging service in Magnetic Resonance Imaging is one of the most important specialization of Ephoran in particular for the evaluation of the contrastographic properties of novel contrast agents and for the application of MRI in the assessment of the therapeutic properties of drugs.

MRI uses radiofrequency waves and a strong magnetic field to provide remarkably clear and detailed pictures of internal organs and tissues. Radiofrequency waves are directed at protons, the nuclei of hydrogen atoms, in a strong magnetic field. The protons are first "excited" and then "relaxed," emitting radio signals that can be computer-processed to form an image. In the body, protons are most abundant in the hydrogen atoms of water, so that an MRI image shows differences in the water content and distribution of various body tissues.
This imaging system is particularly suitable for the simultaneous acquisition of both anatomic and metabolic information. While anatomic resolution (<100 µm) requires long acquisition times and weak magnetic fields (1.5-2 T), functional data usually rely on faint signals that need strong magnetic fields (3-10 T) and rapid scans. This is particularly challenging when applied to small animals, in which a short acquisition time would ultimately result in an important drop in spatial resolution. As a consequence, functional data in small animals usually require the administration of appropriate tracers that enhance the signal relative to a given biological function.

The expertise of experimental imaging teams and the availability of MR equipments covering a wide spectrum of magnetic fields provides for a complete range of platform applications. Preclinical MRI is performed on state-of-the-art systems:

Expertise of Ephoran's founders guarantees outstanding knowledge in MRI technique in particular in the design and synthesis of dedicated contrast agents and in their applications in animal model testing. Molecular targeted contrast media for MRI and scanning techniques targeting specific molecular or cellular processes are available, with applications including different pathological conditions such as oncology (from tumor cells to xenograft and orthotopic animal models), inflammatory processes (arthritis, neuro-degeneration), cardiovascular diseases (plaque imaging in model of induced pathology and of transgenic animal models ) and CNS pathologies (diffusion weighted MRI, functional MRI). Ephoran has developed strong and qualified scientific collaborations in this field in particular with academia and research institutions.
