ARDMS Echo Echo Report Interpretation and Quality Assurance

Question 1

Which echocardiographic artifact is caused by a strong reflector re-reflecting the ultrasound beam, creating a false image deeper in the field?

Accepted Answer

Reverberation artifact

Answer

Shadowing

Answer

Side-lobe artifact

Answer

Refraction artifact

Question 2

What does a 'technically limited' echocardiogram report indicate about image quality?

Accepted Answer

At least one key structure could not be adequately visualized, limiting diagnostic confidence

Answer

All structures were fully visualized

Answer

The study was performed suboptimally due to technologist error only

Answer

The patient refused part of the examination

Question 3

Which ARDMS Echo exam domain focuses on the sonographer's ability to optimize image quality and perform measurements correctly?

Accepted Answer

Instrumentation and image optimization

Answer

Patient care and safety

Answer

Cardiac anatomy

Answer

Electrocardiographic interpretation

Question 4

Near-field clutter (NFC) is best reduced by:

Accepted Answer

Using harmonic imaging and adjusting near-field compression

Answer

Increasing overall gain

Answer

Decreasing frequency and increasing depth

Answer

Increasing color Doppler scale

Question 5

When reviewing an echocardiogram report, an LV wall motion score index (WMSI) of 1.0 indicates:

Accepted Answer

Normal wall motion in all segments

Answer

Severely abnormal global function

Answer

Mild hypokinesis in one segment

Answer

Akinesis in multiple segments

Question 6

What is the primary purpose of an accreditation program such as the Intersocietal Accreditation Commission (IAC) for echocardiography laboratories?

Accepted Answer

To ensure echocardiography laboratories meet standards for quality patient care and diagnostic accuracy

Answer

To certify individual sonographers

Answer

To approve reimbursement codes for echo studies

Answer
