ARDMS AB-Abdomen Exam Questions

Exam Name: Abdomen Sonography Examination
Exam Code: AB-Abdomen
Related Certification(s): ARDMS Registered Diagnostic Medical Sonographer Certification
Certification Provider: ARDMS
Number of AB-Abdomen practice questions in our database: 165 (updated: Feb. 21, 2026)
Expected AB-Abdomen Exam Topics, as suggested by ARDMS :
  • Topic 1: Anatomy, Perfusion, and Function: This section of the exam measures the skills of abdominal sonographers and focuses on evaluating the physical characteristics, blood flow, and overall function of abdominal structures. Candidates must understand how to assess organs such as the liver, kidneys, pancreas, and spleen for size, shape, and movement. It also involves analyzing perfusion to determine how effectively blood circulates through these organs. The goal is to ensure accurate interpretation of both normal and abnormal functions within the abdominal cavity using sonographic imaging.
  • Topic 2: Pathology, Vascular Abnormalities, Trauma, and Postoperative Anatomy: This section of the exam evaluates the abilities of diagnostic medical sonographers and covers the detection and analysis of diseases, vascular issues, trauma-related damage, and surgical alterations in abdominal anatomy. Candidates are expected to identify abnormal growths, inflammations, obstructions, or vascular irregularities that may affect abdominal organs. They must also recognize post-surgical changes and assess healing or complications through imaging. The emphasis is on correlating pathological findings with clinical data to produce precise diagnostic reports that guide further medical management.
  • Topic 3: Abdominal Physics: This section of the exam measures the knowledge of ultrasound technicians in applying imaging physics principles to abdominal sonography. It includes understanding how to optimize ultrasound equipment settings for the best image quality and how to identify and correct imaging artifacts that can distort interpretation. Candidates should demonstrate technical proficiency in handling transducers, adjusting frequency, and managing depth and gain to obtain clear, diagnostic-quality images while minimizing errors caused by acoustic artifacts.
  • Topic 4: Clinical Care, Practice, and Quality Assurance: This section of the exam tests the competencies of clinical ultrasound specialists and focuses on integrating patient care standards, clinical data, and procedural accuracy in abdominal imaging. It assesses the candidate ability to follow established medical guidelines, ensure correct measurements, and provide assistance during interventional or diagnostic procedures. Additionally, this domain emphasizes maintaining high-quality imaging practices and ensuring patient safety. Effective communication, adherence to protocols, and continuous quality improvement are key aspects of this section.

In the exam, the Anatomy, Perfusion, and Function topic came up, and I relied on Pass4Success practice questions to guide me through hepatic vein hemodynamics and portal triad anatomy. One challenging question asked to identify which vascular structure is most related to the porta hepatis perfusion pattern when comparing normal portal vein flow velocity with altered hepatic arterial flow, including sample Doppler traces and a deceleration index. I was unsure if the correct pick was portal vein velocity or hepatic artery resistive index, yet the practice bank helped me reason through the relationships and I ended up passing.

The day of the test felt intense, but I credit Pass4Success practice questions for helping me nail the Pathology, Vascular Abnormalities, Trauma, and Postoperative Anatomy section, especially distinguishing consequences of blunt abdominal trauma on solid organs versus hollow viscera. A memory of an exam question described a patient with suspected splenic laceration and asked which ultrasound findings most strongly indicate rupture, including subcapsular hematoma size, free intra-abdominal fluid, and organ contour irregularity. I was unsure whether to emphasize free fluid in Morrison’s pouch versus in the hepatorenal recess, but the practice sets steered me toward recognizing subtle perisplenic fluid as a critical clue, and I passed.

After a long study period, I finally passed the exam with the aid of Pass4Success practice questions, this time focusing on Clinical Care, Practice, and Quality Assurance, particularly the development of standardized reporting templates and image-optimization protocols. I recall an exam item about ensuring QA in a busy ultrasound suite: selecting the most appropriate daily quality control phantom test to verify axial resolution, lateral resolution, and depth calibration. I wasn’t entirely sure which parameter was prioritized for post-processing validation, yet the overall QA framework clarified the right choice, and I pulled through to pass.

I just passed the Abdomen Sonography exam, and the last stretch really pressed on my confidence with the Anatomy, Perfusion, and Function topics, especially distinguishing hepatic arterial vs portal venous flow patterns; Pass4Success practice questions helped reinforce the concepts, though I still hesitated on a question about differentiating segmental hepatic perfusion on color Doppler. The question described a patient with cirrhosis and asked which Doppler parameter best distinguishes compensated from decompensated liver function, including velocity, resistive index, and waveforms, and I wasn’t sure if the correct answer was increased resistive index or altered systolic velocity, but the practice sets nudged me toward understanding waveform morphology across segments.

Free ARDMS AB-Abdomen Exam Actual Questions

Note: Premium Questions for AB-Abdomen were last updated On Feb. 21, 2026 (see below)

Question #1

Elevation of alpha-fetoprotein levels is a characteristic finding in which tumor?

Reveal Solution Hide Solution
Correct Answer: A

Alpha-fetoprotein (AFP) is commonly elevated in patients with hepatocellular carcinoma (hepatoma), particularly in those with underlying cirrhosis or chronic hepatitis B/C. AFP is not typically elevated in adenomas, cholangiocarcinoma, or FNH.

According to Rumack's Diagnostic Ultrasound:

''Serum AFP levels are elevated in 50--70% of patients with hepatocellular carcinoma.''

Question #2

Where in the neck are most thyroid cancer recurrences found?

Reveal Solution Hide Solution
Correct Answer: B

Most thyroid cancer recurrences are found in the ipsilateral neck---particularly in the central (level VI) or lateral (levels II-V) compartments on the same side as the original malignancy.

According to AIUM Practice Parameters:

''Post-thyroidectomy recurrence most frequently occurs ipsilateral to the original tumor, commonly involving regional lymph nodes.''


AIUM Practice Parameter for Thyroid and Neck Ultrasound, 2020.

American Thyroid Association (ATA) Guidelines for Thyroid Cancer Management, 2015.

Question #3

Which technique would best assist the sonographer to verify the finding in this image obtained from the right upper quadrant?

Reveal Solution Hide Solution
Correct Answer: D

The image demonstrates a gallbladder with a possible echogenic focus (likely a gallstone) and posterior acoustic shadowing. This is suggestive of cholelithiasis. To differentiate uncomplicated gallstones from acute cholecystitis, the most effective technique is to assess for a positive sonographic Murphy sign.

A positive sonographic Murphy sign refers to the presence of focal tenderness over the gallbladder when it is directly palpated with the ultrasound transducer. It is a strong indicator of acute cholecystitis when combined with other features such as gallbladder wall thickening, pericholecystic fluid, and gallstones.

Sonographic Murphy sign --- key points:

Assessed during real-time scanning

Localized tenderness when pressure is applied over the gallbladder

Highly sensitive for acute cholecystitis (especially in the presence of stones)

Differentiation from other options:

A . Use compound imaging: Improves image quality by reducing artifacts but does not verify tenderness or confirm acute inflammation.

B . Change the patient's position: Helpful to confirm mobility of gallstones, but not diagnostic of inflammation.

C . Ask patient to perform Valsalva: Used primarily in vascular studies (e.g., assessing for varicocele or venous reflux), not relevant here.

Question #4

Which description is associated with the normal sonographic appearance of a tendon?

Reveal Solution Hide Solution
Correct Answer: A

On ultrasound, tendons appear as cord-like hyperechoic structures with linear fibrillar echotexture when imaged in long axis. The fibrils are highly reflective, creating the typical hyperechoic appearance. Posterior shadowing is not typical unless there is calcification.

According to Rumack's Diagnostic Ultrasound:

''Tendons have a highly organized hyperechoic linear fibrillar pattern when examined along their long axis.''

Question #5

Which is the most likely etiology of a spherical mass near the splenic hilum that is isoechoic to the normal spleen in a 55-year-old female?

Reveal Solution Hide Solution
Correct Answer: B

An accessory spleen (splenule) is a congenital variant, commonly located near the splenic hilum, and has identical echogenicity to the native spleen. This finding is benign and often incidental.

According to Rumack's Diagnostic Ultrasound:

''Accessory spleens are typically found near the splenic hilum and are isoechoic to the normal splenic parenchyma.''
