Objectives: After studying the article entitled “Echo Intensity Reliability From Two Ultrasound Systems,” you will be able to:
Explore the echo intensity (EI) reliability between two different ultrasound machines
Review the techniques used to increase image optimization between machines
Discuss the strategies used to improve the reliability between images obtained from different ultrasound systems
Echo intensity values have been used to evaluate the following except: Effects of aging Neuromuscular diseases Lung capacity Strength-training adaptations
Which is not considered an image optimization technique that generates excellent quality measurements? Loop count Depth Gain Frequency
Reliability studies have been conducted to quantify the following except: Influence of moments Homogeneous associations Raters Transducer tilt
What did the results of the current study demonstrate? There is no difference in EI values between systems. This was an inconclusive study, providing little information when comparing EI values. The absolute values obtained from these systems can easily be compared. EI values are different between ultrasound systems, greatly influenced by frequency and gain.
The values obtained for different systems and parameters presented: Large standard deviations Equivocal indices Low standard deviations Low mean deviation
