Sonosim Exam 1 questions with
complete solutions already passed
Long axis vs. short axis view- how are this view related to the positioning of the transducer? -
correct answer ✔✔Rotate transducer 90* to switch
How does the angle of intonation affect the ultrasound image quality? - correct answer ✔✔Can
minimize scatter by reducing angle
What is an anisotropic artifact? How is this related to the angle of intonaco? - correct answer
✔✔Properties that differ according to view. Tendons are most anisotropic. If angle is not
perpendicular, you get the artifact
Why do bones typically have a hyperechoic cortex with anechoic underlying tissue? What is this
phenomenon referred to? - correct answer ✔✔Hard tissue (dense) and strongly reflects waves.
Acoustic shadow
Describe the normal appearance of muscle tissue using the terms hyperechoic and hypoechoic.
- correct answer ✔✔Hypoechoic appearance relative to other structures
Compare the appearance of tendons to muscle tissue. - correct answer ✔✔Tendons are
hyperechoic
What are the possible conclusions that can be reached when a tendon appears discontinuous in
a long axis view? What can be done to better determine the cause of this observation? - correct
answer ✔✔True interruption = injury
Oblique angle = anasotrpy
, How does transducer frequency affect penetration and image quality? - correct answer
✔✔Higher frequency = better for superficial stuff and better image
How does the image produced with a linear vs. curvilinear transducer differ? - correct answer
✔✔Curvilinear = wedged shaped image
Linear = box shaped image
Describe the conventional transducer orientation for MSK sonography. - correct answer
✔✔Orient toward right side or in a cephalad direction
--- - correct answer ✔✔---
Which of the capsular ligaments of the hip joint can most easily be visualized using sonography?
- correct answer ✔✔Iliofemoral ligament
Describe the boundaries and contents of the femoral triangle. - correct answer ✔✔Sartorius -
lateral
Inguinal ligament - superior oblique
Adductor longus - medial
Medial floor - pectineous and adductor longous
Lateral floor - Illiopsoas
Contents medial to lateral - femoral vein, artery, nerve
What two muscles can be seen attaching to the anterior superior iliac spine? - correct answer
✔✔Tensor fasciae latae (laterally) and sartorious (medially)
How should the patient's lower limb be position to view structures in the medial compartment
of the thigh? - correct answer ✔✔Thigh abducted and externally rotated
