1. A structure that appears completely black on ultrasound is
described as:
A. Hyperechoic
B. Hypoechoic
C. Isoechoic
D. Anechoic
Rationale: Anechoic structures produce no internal echoes and
appear black, typical of cysts or fluid.
2. The most common frequency used for adult abdominal
ultrasound is:
A. 10–15 MHz
B. 2–5 MHz
C. 7–12 MHz
D. 15–20 MHz
,Rationale: Lower frequencies penetrate deeper for abdominal
imaging.
3. Which organ lies in the retroperitoneum?
A. Spleen
B. Liver
C. Gallbladder
D. Kidneys
Rationale: Kidneys are retroperitoneal; liver and spleen are
intraperitoneal.
4. The best patient position for gallbladder imaging is:
A. Prone
B. Supine
C. Left lateral decubitus
D. Semi-erect
Rationale: Left lateral decubitus helps separate the
gallbladder from bowel gas.
5. Murphy’s sign is associated with:
A. Appendicitis
B. Pancreatitis
,C. Acute cholecystitis
D. Renal colic
Rationale: Inspiratory arrest during gallbladder palpation
indicates cholecystitis.
6. Which Doppler setting reduces aliasing?
A. Lower PRF
B. Increase gain
C. Increase PRF/scale
D. Decrease wall filter
Rationale: Increasing PRF increases Nyquist limit and reduces
aliasing.
7. The normal CBD diameter should be:
A. 2–4 mm
B. 6–10 mm
C. Up to 6 mm
D. 10–15 mm
Rationale: Normal CBD ≤6 mm; may increase with age and
post-cholecystectomy.
8. Which pathology shows a “target” or “pseudokidney” sign?
, A. Cholelithiasis
B. Intussusception
C. Appendicitis
D. Bowel obstruction
Rationale: Intussusception creates concentric bowel layers
giving a target appearance.
9. The preferred probe for thyroid ultrasound is:
A. Curvilinear 2–5 MHz
B. Phased array 2 MHz
C. Linear 7–15 MHz
D. Endocavitary 5–9 MHz
Rationale: High-frequency linear transducers are ideal for
superficial structures.
10. A simple cyst must NOT have:
A. Anechoic content
B. Smooth borders
C. Posterior enhancement
D. Internal echoes
Rationale: Any internal echoes make it a complex cyst.
