Abstract
Aim.In this study, we set out to determine the informative value of multi-parametric ultrasound examination using ultrasound elastography in the differential diagnosis of thyroid nodular neoplasms.Materialsand methods. We analysed 229 multi-parametric ultrasound examinations of patients in the preoperative period in order to assess the effectiveness of strain elastography (SE) and shear wave elastography (SWE) drawing on the example of ARFI and Strain Ratio. Two patient groups were formed. The fi rst group (N1=93) included patients with thyroid cancer, whereas the second one (N2=136) was composed of patients with benign thyroid nodules (thyroid adenoma and follicular or colloid goitre). The control group consisted of 174 patients with unchanged thyroid parenchyma. SE visualised tissue elasticity as a colour map. Shear wave elastography (SWE) — ARFI and Strain Ratio techniques — was performed using the following ultrasonic apparatuses: Acuson S-2000 (Siemens, Germany), Ultrasonix SP (Sonix, Canada) and Mindray DC-8 (Mindray, China).Results.According to the obtained data (SE technique), the parenchyma of the unchanged thyroid gland exhibited heterogeneous, uneven fi ne / moderately granular, symmetrical staining (96.6%). Thyroid cancer was characterised by a shear wave velocity (ARFI) of greater than 3.57 m/s, as well as a density ratio (elasticity modulus and Strain Ratio) of more than 1.56.Conclusion.The study revealed that the application of ultrasound elastography is highly informative in the comprehensive diagnosis of thyroid nodular neoplasms and should be used when thyroid cancer is suspected to ascertain the size of nodules, as well as the tumour invasion into surrounding tissues.
Highlights
Но до сих пор остается актуальным вопрос оценки эффективности комплексного применения современных опций мультипараметрического ультразвуковое исследование (УЗИ) в дифференциальной диагностике узловых новообразований щитовидной железы (ЩЖ) для формирования лечебной тактики, а также решения вопроса о необходимости и объеме оперативного вмешательства

Summary
Но до сих пор остается актуальным вопрос оценки эффективности комплексного применения современных опций мультипараметрического УЗИ в дифференциальной диагностике узловых новообразований ЩЖ для формирования лечебной тактики, а также решения вопроса о необходимости и объеме оперативного вмешательства. Цель исследования — определить информативную ценность мультипараметрического УЗИ с применением ультразвуковой эластографии в дифференциальной диагностике узловых новообразований ЩЖ. Характеристики узловых образований ЩЖ различной морфологической структуры при использовании режима КЭГ Table 1. Далее в ходе исследования у этих же пациентов с раком ЩЖ и доброкачественными образованиями ЩЖ был проведен анализ данных, полученных при ультразвуковой эластометрии на примере ARFI (Siemens Acuson S 2000) и Strain Ratio (Mindray DC-8).
