Normal reference ranges for echocardiography: do we really need more?

Echocardiography is themostwidelyusednon-invasivecardiac imaging for assessing the cardiac structure and function. Echocardiography has the advantage of low cost, no radiation risk, and great availability. However, as for any diagnostic test, its interpretation depends on its ability to accurately detect abnormalities. Actually, the definition of ‘abnormal’ relies on the definition of ‘normal’ ...

A Machine Learning Approach to No-Reference Objective Video Quality Assessment for High Definition Resources

The video quality assessment must be adapted to the human visual system, which is why researchers have performed subjective viewing experiments in order to obtain the conditions of encoding of video systems to provide the best quality to the user. The objective of this study is to assess the video quality using image features extraction without using reference video. RMSE values and processing ...

Reference interval for thyrotropin in a ultrasonography screened Korean population

BACKGROUND/AIMS The diagnostic accuracy of thyroid dysfunctions is primarily affected by the validity of the reference interval for serum thyroid-stimulating hormone (TSH). Thus, the present study aimed to establish a reference interval for TSH using a normal Korean population. METHODS This study included 19,465 subjects who were recruited after undergoing routine health check-ups. Subjects w...
