Magnetic Resonance Imaging (MRI) has revolutionised the field of medicine by detecting the progress and staging of diseases particularly tumours which has proved quite helpful in cancer detection. Use of magnetic nanoparticles is involved in RF induced ablation, where hyperthermia might be vague coupled through MRI as nanoparticles of magnetic nature are targeted for imaging of the tumour cells. RF can also be transformed into heat to kill tumour cells. Nanoparticles of super paramagnetic iron oxides as suspension or fluid are to interact with the magnetic field to act as a contrast agent. The magnetic energy gets transformed into internal energy which is finally transformed into thermal energy through Brownian and Neel relaxation inside the nanoparticles. While carrying out Magnetic Resonance Imaging (MRI), many challenges have been faced by medical professionals due to the presence of prosthetics and other types are being of implants like crowns, FPDs, etc. Artifacts provide a major resistance in the path of MRI and thus form distorted images and loss of useful information.
