True or false: Artifacts left on or within the patient can always be removed later during analysis.

• A. True
• B. False
• C. Sometimes
• D. Depends on the artifact

Answer: (B)

The statement is false. Artifacts that are present on or within the patient during a bone densitometry examination cannot always be removed later during the analysis. Artifacts can arise from a variety of sources, including patient movement, presence of metal (such as jewelry or dental work), or environmental factors, among others. When these artifacts are present during the imaging process, they may distort the results and potentially lead to inaccuracies in bone density measurements. While some image processing techniques might help mitigate certain types of artifacts after the fact, not all artifacts can be effectively corrected. For example, significant motion or dense metal artifacts often result in irreversible alterations to the image data that cannot be removed through post-processing. Understanding the limitations of artifact correction is crucial in bone densitometry, as it emphasizes the importance of careful preparation and positioning of the patient prior to the scan to ensure the integrity of the results. This preemptive approach is essential for achieving accurate assessments of bone density and preventing misinterpretation of the images.
