1. The ultrasound features of RA include:
- synovial hypertrophy
- extensor carpi ulnaris tenosynovitis
- cortical bone erosion
- posterior tibialis tenosynovitis among affected joints
- All of the above
2. Which test is more sensitive for detection of occult joint inflammation?
- physical examination.
- ultrasound with gray scale.
- ultrasound with both gray scale and power Doppler.
- X ray.
3. Which is the benefit of 40-joint ultrasound program for RA?
- enhance the early detection of RA
- enhance early intervention for RA and promote long-term remission of RA
- evaluate the intensity of joint inflammation
- All of the above
4. The application of ultrasound in RA patients receiving biologic agents includes?
- evaluate the treatment response of biologics
- facilitate the detection of occult inflammation after biologic dose reduction
- provide the guidance of biologic dose modification
- All of the above
5. Which tendon does xanthoma often involve?
- Achilles tendon.
- Flexor tendons of hands.
- Supraspinatus tendon.
- Quadriceps tendon.
6. Which statement regarding xanthoma is not true?
- Xanthoma is a disorder that lipid deposit in the connective tissue.
- Xanthoma is highly relevant to the lipid metabolism disorders, such as familial hypercholesterolemia.
- Sonographic findings of xanthoma include hypoechoic and hyperechoic confluences, and increased signals under the power Doppler mode.
- Thickened Achilles tendon in xanthoma is more predominant at proximal part.
7. Which one is not the roles of ultrasounds in evaluating xanthoma?
- To correlate with low-density lipoprotein (LDL) level regarding Achilles tendon thickness.
- To differentiate the etiology of posterior ankle pain.
- To confirm the diagnosis of xanthoma as a gold standard.
- To follow the improvement of xanthoma after taking medications, such as statin.
8. As an expert for the ultrasonography, which statement is wrong?
- The posterior enhancement is the typical finding of effusion or a cyst.
- The acoustic shadowing is the typical finding of calcification.
- When performing the aspiration through ultrasound guidance, the reverberation is the typical finding of the needle shaft.
- 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)?
- SCI uses electronic beam steering to generate several overlapping images of a single object.
- SCI reduces artifacts made by lateral dispersion of residual off-axis beams, reverberations, and reflections.
- The frame rate will be increased.
- The higher number of overlapping images, the better resolution and contrast.
10. For image optimization, which statement is wrong?
- We can use tilting or light compression of the transducer to decrease the anisotropy.
- Turning on spatial compound imaging can decrease the artifact of posterior enhancement.
- Turning on spatial compound imaging can improve the quality of the images.
- Ultrasound beams transmitting with different angles of insonation can improve the quality of the image.
