Which factor helps to eliminate motion artifacts in imaging?

High speed of data acquisition is essential for minimizing motion artifacts in imaging. When imaging processes are conducted quickly, there is less time for patient movement to occur during the scan. Motion artifacts can arise from a variety of sources, including involuntary movements like breathing or voluntary actions like shifting position. Quick data acquisition ensures that the imaging system can capture the necessary information before significant motion affects the resulting images, leading to clearer and more accurate representations of the anatomy being studied.

Other factors may have relevance in imaging quality but do not directly impact the issue of motion artifacts as effectively as high-speed acquisition. For instance, using a low radiation dose can limit patient exposure but does not address the time available for movement to occur. Contrast media enhances visibility of structures within the body but does not reduce artifacts caused by movement. While thin slice thickness can provide finer detail, it does not specifically counteract the effects of motion during the imaging process. Thus, high speed of data acquisition is the most effective solution to eliminate motion artifacts in imaging.
