Abstract.
Objectives. To assess the reproducibility of determining ultrasound indices of visceral adipose tissue amount of various localization.
Material and methods. The reproducibility evaluation of visceral adipose tissue amount ultrasound determination methods was performed in 47 patients aged from 18 to 60 years. The results comparability of visceral adipose tissue measurements performed by one and the same researcher was estimated in 24 patients and consistency of the conclusions of several other researchers with different operational experience – in 23 people. The ultrasound study was conducted on the following devices: «ProSound Alpha 7» (Hitachi-Aloka Medical, Ltd., Japan), «Aplio 500» (Toshiba, Japan), «Logiq E9» (GE Healthcare, USA ) equipped with a 3,5-MHz convection sensor.
The reproducibility of visceral adipose tissue ultrasound indices measurement results, performed repeatedly by one and two researchers in succesion, was evaluated by two methods. One of the methods was based on kappa index calculating, and the second one was performed using the Bland-Altman statistical analysis method.
Results. The reproducibility evaluation of the results of visceral adipose tissue amount ultrasound determination, performed by one and two researchers showed their good consistency.
Conclusions. Thus, ultrasound methods of visceral adipose tissue amount determination allow to obtain highly reproducible results. A reliable diagnosis of visceral obesity creates prerequisites for determining cardiovascular complication development risk factors affecting the prognosis of the patient’s life.
Key words: visceral adipose tissue, ultrasound investigation, reproducibility.
