1. The ultrasound features of RA include:

  1. synovial hypertrophy
  2. extensor carpi ulnaris tenosynovitis
  3. cortical bone erosion
  4. posterior tibialis tenosynovitis among affected joints
  5. All of the above


2. Which test is more sensitive for detection of occult joint inflammation?

  1. physical examination.
  2. ultrasound with gray scale.
  3. ultrasound with both gray scale and power Doppler.
  4. X ray.


3. Which is the benefit of 40-joint ultrasound program for RA?

  1. enhance the early detection of RA
  2. enhance early intervention for RA and promote long-term remission of RA
  3. evaluate the intensity of joint inflammation
  4. All of the above


4. The application of ultrasound in RA patients receiving biologic agents includes?

  1. evaluate the treatment response of biologics
  2. facilitate the detection of occult inflammation after biologic dose reduction
  3. provide the guidance of biologic dose modification
  4. All of the above


5. Which tendon does xanthoma often involve?

  1. Achilles tendon.
  2. Flexor tendons of hands.
  3. Supraspinatus tendon.
  4. Quadriceps tendon.


6. Which statement regarding xanthoma is not true?

  1. Xanthoma is a disorder that lipid deposit in the connective tissue.
  2. Xanthoma is highly relevant to the lipid metabolism disorders, such as familial hypercholesterolemia.
  3. Sonographic findings of xanthoma include hypoechoic and hyperechoic confluences, and increased signals under the power Doppler mode.
  4. Thickened Achilles tendon in xanthoma is more predominant at proximal part.


7. Which one is not the roles of ultrasounds in evaluating xanthoma?

  1. To correlate with low-density lipoprotein (LDL) level regarding Achilles tendon thickness.
  2. To differentiate the etiology of posterior ankle pain.
  3. To confirm the diagnosis of xanthoma as a gold standard.
  4. To follow the improvement of xanthoma after taking medications, such as statin.


8. As an expert for the ultrasonography, which statement is wrong?

  1. The posterior enhancement is the typical finding of effusion or a cyst.
  2. The acoustic shadowing is the typical finding of calcification.
  3. When performing the aspiration through ultrasound guidance, the reverberation is the typical finding of the needle shaft.
  4. In order to decrease the artifact of acoustic shadowing, we can increase the gain of the ultrasound.


9. For image optimization, which statement is wrong of spatial compound imaging (SCI)?

  1. SCI uses electronic beam steering to generate several overlapping images of a single object.
  2. SCI reduces artifacts made by lateral dispersion of residual off-axis beams, reverberations, and reflections.
  3. The frame rate will be increased.
  4. The higher number of overlapping images, the better resolution and contrast.


10. For image optimization, which statement is wrong?

  1. We can use tilting or light compression of the transducer to decrease the anisotropy.
  2. Turning on spatial compound imaging can decrease the artifact of posterior enhancement.
  3. Turning on spatial compound imaging can improve the quality of the images.
  4. Ultrasound beams transmitting with different angles of insonation can improve the quality of the image.
