ARDMS Echo Echo Report Interpretation and Quality Assurance 1

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

Reverberation artifacts appear as equally spaced parallel lines deeper than the true reflector, caused by the beam bouncing between two strong interfaces.

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

A 'technically limited' study means one or more cardiac structures were inadequately visualized, potentially affecting the completeness or accuracy of the report.

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

Instrumentation and image optimization is a core ARDMS Echo exam domain, covering transducer selection, gain settings, depth, focus, and artifact recognition.

Question 4

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

Accepted Answer

Using harmonic imaging and adjusting near-field compression

Answer

Harmonic imaging and near-field compression/reject controls reduce near-field clutter by suppressing low-amplitude fundamental frequency noise close to the transducer.

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

WMSI is calculated by dividing total wall motion score by number of segments; a score of 1.0 means all segments are normal (each scored 1 = normal).
