What is one effective method for reducing metal artifacts?

Increasing the receive bandwidth is an effective method for reducing metal artifacts in imaging. This approach helps because a wider receive bandwidth allows for a broader range of frequencies to be captured during the imaging process. By capturing more frequency data, the system is better equipped to differentiate between the signals from different tissues and to reduce the contribution of the distorted signals caused by metal.

Metal implants can create artifacts due to their high density and the differences in magnetic susceptibility between the metal and surrounding tissues, leading to distortions in the images. When the receive bandwidth is increased, the images can be reconstructed more accurately because the MRI system can better resolve the variations in the signal caused by the presence of metal.

Utilizing pulse sequence modifications and changing the imaging modality can also potentially help in artifact reduction, but these methods might not be as direct or effective as simply increasing the receive bandwidth in many scenarios. Adjusting slice thickness can affect image resolution but does not specifically address the artifacts created by metal. Therefore, increasing the receive bandwidth stands out as a direct and effective means of mitigating metal artifacts during imaging procedures.
