Under some circumstances, the complex electrodynamic
interactions between the subject and the incident RF
field can distort RF excitation to such an extent that
the diagnostic value of MRI is compromised. Metal
implants, in particular, are a well-known source of MR
artifacts, resulting not only from distortion of the
main magnetic field, but also from distortions of the
excitation RF field. In this work, we explore the
potential of a generalized implementation of the
recently proposed plug & play parallel transmission
framework, to enable rapid multiparamatric mapping (T1,
T2, PD) in the presence of orthopedic implants.
