Question 1

Which obstetric Doppler measurement in the umbilical artery, when absent or reversed, indicates severe fetal compromise requiring urgent evaluation?

Accepted Answer

End-diastolic flow

Answer

Absent or reversed end-diastolic flow in the umbilical artery reflects extreme placental resistance and is associated with high risk of fetal hypoxia and perinatal death.

Question 2

On a neonatal hip ultrasound using the Graf method, an alpha angle of 50 degrees indicates:

Accepted Answer

Physiologically immature hip (Type IIa)

Answer

Graf alpha angles of 50–59 degrees in infants <3 months are classified as Type IIa (physiologically immature), which may resolve with close follow-up.

Question 3

A patient with a palpable neck mass undergoes ultrasound showing a cystic structure at the anterior border of the sternocleidomastoid muscle at the junction of its upper and middle thirds. This location is classic for:

Accepted Answer

Second branchial cleft cyst

Answer

Second branchial cleft cysts classically occur along the anterior border of the SCM at the junction of its upper and middle thirds.

Question 4

When performing a transrectal ultrasound (TRUS) of the prostate, the normal peripheral zone echogenicity compared to the central gland is:

Accepted Answer

Isoechoic to slightly hyperechoic

Answer

The peripheral zone normally appears isoechoic to mildly hyperechoic relative to the central gland on TRUS; hypoechoic foci within it raise concern for prostate carcinoma.

Question 5

Which finding on abdominal aorta ultrasound defines an aneurysm requiring vascular surgery referral in most US guidelines?

Accepted Answer

Aortic diameter ≥5.5 cm

Answer

An aortic diameter ≥5.5 cm in men (≥5.0 cm in some guidelines for women) is the threshold at which surgical or endovascular repair is generally recommended.
