EXAM OVERVIEW
The Pediatric Sonography (PS) exam is administered by the American Registry for
Diagnostic Medical Sonography (ARDMS) (Inteleos). This specialty exam assesses the
knowledge, skills, and abilities required for pediatric sonography practice.
Exam Component Details
Full Name Pediatric Sonography (PS) Examination
Prerequisite Must pass the Sonography Principles and Instrumentation (SPI) exam within 5 years
Total Questions Approximately 170 questions
Time Allowed 3 hours
Question Types Multiple-choice and hotspot questions (mark directly on images)
Pass/Fail Initial results are Pass/Fail
,📚 CONTENT DOMAINS (Based on ARDMS PS Content
Outline)
The PS exam covers five content domains:
Domain Percentage Approx. Questions
1. Anatomy and Physiology 26% ~43 questions
2. Congenital Variants, Pathology, and Pathophysiology 45% ~74 questions
3. Data and Protocols 19% ~32 questions
4. Physics and Instrumentation 5% ~9 questions
5. Treatment and Emerging Technologies 5% ~9 questions
🧠 350 PRACTICE QUESTIONS WITH RATIONALES
DOMAIN 1: ANATOMY AND PHYSIOLOGY (Questions 1–80)
Q1. In a neonate, the normal anteroposterior (AP) diameter of the right kidney
should not exceed what measurement?
• A) 2.5 cm
• B) 3.5 cm
, • C) 4.5 cm
• D) 5.5 cm
Correct Answer: C
Rationale: In a neonate, the normal AP diameter of the kidney should be ≤4.5 cm. The
kidney length in a full-term neonate is typically 4.0–4.5 cm. Measurements exceeding
this may indicate hydronephrosis or renal pathology.
Q2. The normal thickness of the renal cortex in a pediatric patient should measure
at least:
• A) 2 mm
• B) 4 mm
• C) 6 mm
• D) 8 mm
Correct Answer: B
Rationale: The normal renal cortex should measure at least 4 mm in thickness in
children. Thinning of the cortex may indicate chronic renal disease or obstruction.
Q3. Which of the following correctly describes the normal appearance of the
neonatal adrenal gland on ultrasound?
• A) A triangular structure with a hyperechoic medulla and hypoechoic cortex
• B) A triangular structure with a hypoechoic medulla and hyperechoic cortex
• C) A round structure with uniform echogenicity
• D) A crescent-shaped structure with mixed echogenicity
, Correct Answer: A
Rationale: The neonatal adrenal gland has a characteristic appearance: a hyperechoic
medulla (central echogenic stripe) surrounded by a hypoechoic cortex. The gland is
relatively large in neonates compared to the kidney.
Q4. The normal length of the neonatal liver on ultrasound should not exceed:
• A) 4 cm
• B) 5 cm
• C) 6 cm
• D) 7 cm
Correct Answer: B
Rationale: In a neonate, the liver length should be ≤5 cm. The liver is relatively
prominent in infants but should not extend more than 2–3 cm below the right costal
margin.
Q5. Which of the following is the normal appearance of the neonatal pancreas on
ultrasound?
• A) Hyperechoic compared to the liver
• B) Hypoechoic compared to the liver
• C) Isoechoic compared to the liver
• D) Hyperechoic with prominent pancreatic duct
Correct Answer: A
Rationale: The neonatal pancreas is typically hyperechoic compared to the liver due to
