Which ultrasound indication is listed among the following?

• A. Chronic fatigue
• B. Healthy tissue
• C. Fracture
• D. Acute inflammation

Answer: (D)

Ultrasound is particularly useful for evaluating acute inflammatory processes in soft tissues. In acute inflammation, ultrasound can show tissue edema, possible joint or bursal effusions, and increased blood flow on Doppler, which together help confirm inflammatory activity and guide treatments like injections or aspirations. The other options don’t fit as primary indications: chronic fatigue is a systemic symptom not typically assessed with ultrasound, imaging healthy tissue isn’t an indication, and fractures are usually evaluated with X-ray radiographs (though ultrasound can help in select occult cases, it’s not the standard indication). Therefore, acute inflammation is the best listed indication.
