Insertable inductively coupled volumetric coils for MR microscopy in a human 7T MR system.

ABSTRACT:

Purpose

To demonstrate the capability of insertable inductively coupled volumetric coils for MR microscopy in a human 7T MR system.

Methods

Insertable inductively coupled volume coils with diameters of 26 and 64 mm (D26 and D64 coils) targeted for monkey and mouse brain specimen sizes were designed and fabricated. These coils were placed inside the imaging volume of a transmit/receive knee coil without wired connections to the main system. Signal-to-noise ratio (SNR) evaluations were conducted with and without the insertable coils, and the g-factor maps of parallel imaging (PI) were also calculated for the D64 coil. Brain specimens were imaged using 3D T2∗ -weighted images with spatial resolution of isotropic 50 and 160 μm using D26 and D64 coils, respectively.
