External calibration of the spectral coverage for three-dimensional multispectral MRI

Purpose By combining images created at distinct frequency offsets from the Larmor frequency, three‐dimensional (3D) multispectral imaging (3D‐MSI) sequences help overcome the large spatial frequency dispersion caused by metal implants. This frequency dispersion, however, varies with the implant size, orientation, and composition. Using a MAVRIC 3D‐MSI acquisition, we sought to prospectively calibrate the spectral coverage needed for 3D‐MSI...
