What artifacts may be present in a spine DXA scan?

• A. Vertebral fractures and aortic calcifications
• B. Cardiac abnormalities and liver lesions
• C. Muscle strains and joint dislocations
• D. Urinary tract infections and skin rashes

Answer: (A)

In a spine DXA (Dual-Energy X-ray Absorptiometry) scan, it is essential to recognize that certain artifacts can appear due to the anatomical structures and conditions present in the area being scanned. Vertebral fractures can produce artifacts because they can affect the density readings of the bones being measured. This situation might lead to an erroneous assessment of bone mineral density (BMD). Aortic calcifications, common in older populations, can also interfere with the accuracy of the scan results by affecting the absorption of X-rays in the region of interest, further complicating the interpretation of bone health. The other options include conditions that are not directly related to the specific anatomical focus or the imaging method used in a DXA scan of the spine. Conditions such as cardiac abnormalities or liver lesions do not manifest as artifacts within the spine's density measurement and thus, do not impact the interpretation of a spinal DXA scan. Likewise, muscle strains and joint dislocations are related to soft tissue and joint mechanics rather than the bony structures evaluated in density measurements. Lastly, urinary tract infections and skin rashes are medical conditions entirely unrelated to bone density readings and would not present as artifacts in this type of imaging. Understanding the nature of artifacts helps in accurately interpreting DXA
