What causes artifact on MRI?

Physiologic artifacts are caused by patient movement, including breathing, heartbeat, and blood flow. Artifacts can arise from the inherent physics of the MRI, such as the presence of metal or chemical shift. Finally, the hardware and software involved in constructing MRI images can cause artifacts.
