1. Which is the correct statement of ultrasound preparation for the skin examination?



1. High-frequency apparatus, at least 10MHz, is appropriate for detailed skin observation.
2. Elastography could be applied for the examination of skin stiffness.
3. Linear probe is a better choice for scanning.
4. All are correct.



2. Which is the correct statement of the sonographic finding of psoriatic skin?



1. The epidermis appears as a continuous hyperechoic line, with increase thickness.
2. A hypoechoic band could be observed between epidermis and dermis.
3. Both (A) and (B) are correct.
4. Both (A) and (B) are incorrect.



3. Which is the correct statement of the sonographic finding of scleroderma?



1. Increase thickness at both epidermis and dermis.
2. Elastography is beneficial for diagnosis.
3. skin thickness and stiffness are associated with scleroderma disease activity.
4. All are correct.



4. Ultrasound is helpful for the differential diagnosis between psoriatic arthritis (PsA) and rheumatoid arthritis (RA). Which of the sonographic finding is correct?



1. RA may reveal bone erosion, but PsA dose not.
2. PsA may reveal synovial hypertrophy, but RA dose not.
3. PsA may involve entheses.
4. PsA dose not involve tendon.



5. What is true about the definition of sonographic anomalies in rheumatoid synovitis?



1. Presence of hypoechoic synovial hypertrophy.
2. Presence of joint effusion.
3. Presence of increased power Doppler signal.
4. Presence of bone erosions.



6. What is true about the definition of sonographic anomalies in rheumatoid tenosynovitis?



1. Presence of hypoechoic or anechoic thickened tissue within the tendon sheath.
2. Presence of fluid within the tendon sheath.
3. Presence of Doppler signal within the tendon sheath.
4. Presence of retraction sign within the tendon sheath.



7. What is true about the application of musculoskeletal ultrasound in rheumatoid arthritis (RA)?



1. Musculoskeletal ultrasound can detect anatomical change but no evidence to guide therapeutic response for RA.
2. The clinical examination is more sensitive than musculoskeletal ultrasound to detect synovitis and tenosynovitis in RA.
3. Musculoskeletal ultrasound has strong evidence superior than clinical examination in detection of inflammation and evaluation of disease activity for RA.
4. Because the clinical remission for RA is hardly achievable so the therapeutic response guided by ultrasound is not recommended.



8. What is true about the application of semiquantitative scoring system in rheumatoid arthritis (RA)?



1. For rheumatoid synovitis the greyscale and Doppler finding was evaluated together.
2. For rheumatoid tenosynovitis the greyscale score is more reliable than Doppler score.
3. For rheumatoid tenosynovitis, the aim to check two perpendicular planes is to obtain better Doppler signals.
4. Provide strong evidence for rheumatologist to follow up tight control in RA.



9. The diagnosis of malrotation, with an emphasis on the relationship of the SMV and SMA and the so-called “whirlpool sign”. Which is correct?



1. SMV is located to the right anterior of SMA.
2. SMV is located to the right lower of SMA.
3. SMV is located to the left lower of SMA.
4. SMV is located to the left anterior of SMA.



10. The differential diagnosis for small bowel obstruction in neonates includes:

1. Duodenal atresia.
2. Malrotation and volvulus.
3. Jejunoileal atresia.
4. Meconium ileus and meconium peritonitis.
5. All of the above.
