1. A computer-implemented method for performing a scan of a subject utilizing a magnetic resonance imaging (MRI) system, comprising:
initiating, via a processor, a prescan of the subject by an MRI scanner of the MRI system without a priori knowledge as to whether the subject has a metal implant;
executing, via the processor, a metal detection algorithm during a prescan entry point of the prescan to detect whether the metal implant is present in the subject;
determining, via the processor, to proceed with a calibration scan and the scan utilizing predetermined scan parameters when no metal implant is detected in the subject; and
switching, via the processor, into a metal implant scan mode when one or more metal implants are detected in the subject, wherein the prescan entry point comprises a center frequency adjustment entry point, and wherein the metal detection algorithm is configured to detect whether the metal implant is present in the subject based on a center frequency scan of targeted radionuclides.
