Objectives: After studying the article titled “Reliability and Variability Assessment of Femoral Artery Pseudoaneurysm Measurements Between Pre- and Postprocessed B-mode Ultrasound Images,” you will be able to:
Define pseudoaneurysm
State color Doppler and pulsed Doppler characteristics of pseudoaneurysms
Understand the importance that image processing can provide for novice sonographers
What imaging modality is considered the standard for diagnosing femoral artery pseudoaneurysm (FAP)? Ultrasound Conventional angiography MRI CT
Figure 1 demonstrates what classic color flow pattern noted in pseudoaneurysms? Turbulent Mosaic Laminar Yin-Yang
An inherently granular “noise” that degrades image quality is known as: Aliasing Shadowing Speckle Reverberation
An ICC value of <0.60 is considered: Excellent reliability Good reliability Moderate reliability Poor reliability
According to Table 1, what is the average ICC value from the original images for FAP sac width measurements for all observers? 0.99 0.91 0.84 0.73
This study presented comparable results in which the average variability of repeated measures of FAP sac width decreased by what percentage in contrast-enhanced images? 18% 21% 35% 41%
In this study, the average ICC value for FAP neck length increased by what percentage from the segmented images for novice users? 2% 10% 60% 97%
