Good methods for reducing respiratory ghosting artifacts include?

Breath-holding by the patient is a highly effective method for minimizing respiratory ghosting artifacts in imaging. When a patient holds their breath, respiratory motion is significantly reduced during the imaging process. This static state allows for clearer and more detailed images, as the movement that typically causes these artifacts is minimized. In MRI, especially during sequences where motion can introduce blur, having a stable subject is crucial for achieving high-quality images.

While other options may have some influence on image quality, they are not as directly effective in controlling respiratory motion artifacts as breath-holding. For instance, using a lower magnetic field strength might reduce overall signal strength, while increasing the TR value can lead to longer scan times, which may inadvertently introduce more motion artifacts. Adjusting the field of view (FOV) can change the area of imaging but doesn’t necessarily decrease the impact of respiratory motion on the captured images. Therefore, utilizing breath-holding specifically addresses the issue of respiratory motion, making it a preferred technique for reducing ghosting artifacts in imaging procedures.
