SPECIAL-COSY at 7T

Alexander Fuchs¹, Anke Henning¹, Peter Boesiger¹

The ability of 2D spectroscopy to spread spectral information that is otherwise hard to detect into a second frequency dimension makes these type of techniques very interesting. On ultra-high field strength the short relaxation time of interesting metabolite signals makes commonly used localized sequneces like L-COSY or PRESS localized COSY impractical. Hence a suitable localized COSY sequence at 7T was implemented using the SPECIAL sequence. The successful application of SPECIAL for localized COSY at 7T is demonstrated in a phantom and in-vivo measurements.
