It has been established that all frequency encoded imaging acquisitions have encoding limitations that are reached near commonly encountered implants at 3T. Here, we present a study whereby the known limitations on clinical MR scanners are modeled in the context of broadband single-point imaging. The resolution, scan time, and T2* signal loss of such a clinically viable single-point-imaging implementation are discussed. It is shown that such an implementation may provide signal directly near metal implants that cannot be acquired via any conventional readout-driven sequence
