502. A patient has been referred for ultrasound evaluation of tendinitis of the wrist. What is the ultrasound appearance of a tendon? a. the sonographic appearance of a tendon varies greatly by location within the body b. tendons are highly echogenic with fibrillar echotexture c. tendons are markedly hypoechoic and homogeneous d. tendons have a heterogeneous sonographic appearance with mixed echodensity e. tendons cannot be recognized sonographically

b. tendons are highly echogenic with fibrillar echotexture

495. A patient has been referred for ultrasound evaluation to rule out the presence of a carotid body tumor. Where is this tumor located? a. at the origin of the CCA on each side of the neck b. lateral to the carotid bifurcation and medial to the sternocleidomastoid muscle c. at the level of the carotid bifurcation between the ICA and ECA d. superomedial to the submandibular gland on each side of the neck e. within the sternocleidomastoid muscle, lateral to the carotid bifurcation

501. What is the sonographic appearance of a normal peripheral nerve? a. markedly hypoechoic structure with scattered bright internal foci b. striated, hypoechoic, linear structure c. markedly hyperechoic structure with parallel internal linear echoes d. homogeneous, hyperechoic, structure with barbell shape e. peripheral nerves cannot be detected sonographically

c. markedly hyperechoic structure with parallel internal linear echoes

503. You detect a hypoechoic region within an otherwise normal appearing tendon. What causes false hypoechogenicity within a tendon? a. use of too much scan gel between the skin and transducer surface b. scanning with the beam perpendicular to the tendons axis c. oblique incidence of the beam to the tendon axis d. use of a transducer frequency greater than 10 MHz e. overuse of receiver gain

c. oblique incidence of the beam to the tendon axis
