摘要
For optimal performance of P-31 MRS at 1.5 Tesla, the use of a double resonant probe is essential to enable the application of H-1 decoupling and Nuclear Overhauser Enhancement. This note describes the design, evaluation and safety validation of a versatile and compact probe optimized for H-1 decoupled P-31 MRS studies of tumors close to the surface of the body, in particular the head and neck region.
