Flexible longitudinal magnetization contrast in spectrally overlapped 3D‐MSI metal artifact reduction sequences: Technical considerations and clinical impact

It has previously been demonstrated that increased overlap of spectral bins in three‐dimensional multispectral imaging techniques (3D‐MSI) can aid in reducing residual artifacts near metal implants. However, increasing spectral overlap also necessitates consideration of saturation effects for species with long T1 values. Here, an interleaved spectral bin acquisition strategy is presented for overlapping 3D‐MSI that allows for flexible choice of repetition times while simultaneously addressing these cross talk concerns.
