Magnetic resonance spectroscopy (MRS) is a non-invasive technique useful both in research and neuroclinical evaluation. It relies on the same physical principles of magnetic resonance imaging providing information on chemical compounds in vivo. MRS uses the magnetic properties of several nuclei such as 13C, 31P and 19F, although the 1H is the most common due to its abundance and magnetic resona...

The development of the paranasal sinuses is an intricate process that begins in the intrauterine life and terminates in early adulthood. Among the paranasal sinuses, the ethmoid cells or labyrinth are probably the most complex structures, being associated with the highest number of normal variants. Variations in the pattern of pneumatization of the ethmoid cells can be divided into intraand ext...

Our Experience with MR Imaging of Perianal Fistulas
Magnetic resonance imaging (MRI) depicts infectious foci in the perianal region better than any other imaging modality. MRI allows definition of the fistula, associated abscess formation and its secondary extensions. Accurate information is necessary for surgical treatment and to obtain a decrease in the incidence of recurrence and complications. Radiologists should be familiar with anatomical ...
