Title: In vivo natural-abundance 17O/1H MRI of Rhesus monkey brain with whole-body scanner and homebuilt multinuclear accessory

Source: Applied Magnetic Resonance

Year : 2003

Abstract:

The construction of an accessory to commercial whole-body magnetic resonance imaging (MRI) scanners that provides multinuclear capability is described. The multinuclear system has access to all clinical pulse sequences and is not limited by the frequency range of the commercially available "spectroscopic package". The accessory was used for O-17 studies with a homebuilt birdcage resonator and a low-noise preamplifier. In vivo O-17 images of a rhesus monkey brain were obtained. The homebuilt birdcage was transparent to radio-frequency irradiation of the scanner's body coil at H-1 frequency allowing consecutive acquisitions of H-1 and O-17 images and their superposition. The results demonstrate the potential of O-17/H-1 imaging with whole-body scanners.
