Abstract
In this work, we present a new RF and gradient assembly for operation in a 9.4 Tesla 189 mm magnet. This assembly was designed in order to enable ^1^H‐NMR perfusion studies that are based on proton‐observed carbon‐edited approaches or gradient selected double quantum coherence. The RF portion of this probe assembly is comprised of a modified Alderman‐Grant coil and a saddle coil operating at 400 and 100 MHz, respectively. These coils are surrounded by an actively shielded Z gradient, which also allows for the use of gradient‐based water suppression without the need for carbon selection. We demonstrate that this probe can be used to implement gradient selected double quantum coherence experiments resulting in a high degree of water suppression.
