“…Эластография сдвиговой волной -метод количественной оценки жесткости ЛУ путем использования специальных усиленных ультразвуковых импульсов (группы импульсов), которые вызывают в тканях вторичные сдвиговые волны, имеющие поперечное направление по отношению к первичным импульсам. Скорость распространения сдвиговых волн прямо пропорциональна жесткости ЛУ [17,18]. Согласно международным рекомендациям ультразвуковую эластографию целесообразно использовать при исследовании поверхностно расположенных ЛУ [19].…”

Цель исследования-определить возможности метода ультразвуковой эластографии лимфатических узлов в качестве дополнительного промежуточного контроля эффективности лечения больных лимфомой Ходжкина. Материалы и методы. В проспективное исследование включены пациенты с диагнозом классической лимфомы Ходжкина с поражением периферических лимфатических узлов. Пациентам выполняли ультразвуковую эластографию (компрессионную эластографию и эластографию сдвиговой волной) измененных лимфатических узлов до лечения и после 2 циклов химиотерапии. Основаниями для проведения ультразвукового исследования периферических лимфатических узлов после 2-го цикла химиотерапии были ранее проведенное ультразвуковое исследование с выявленными изменениями периферических лимфатических узлов (100 %), сохранение пальпируемого образования в проекции поверхностных лимфатических узлов (56,9 %). До ультразвуковой эластографии у исследуемой группы пациентов положительная динамика после 2 циклов химиотерапии была подтверждена данными позитронно-эмиссионной томографии, совмещенной с рентгеновской компьютерной томографией (2-3 балла по шкале Deauville).

Objective: to evaluate the possibilities of ultrasound elastography for differentiation of reactive and lymphomatous superficial lymph nodes (LN).Materials and methods. The prospective study included 138 patients with enlarged superficial LN. Based on a previous histological examination, patients were divided into two groups: 1st group (n = 108) – patients with non-Hodgkin’s lymphomas and Hodgkin’s lymphoma; 2nd (n = 30) – patients with reactive (inflammatory) changes in superficial LN. All patients underwent ultrasound elastography of the enlarged LN using ARFI technology.Results. According to the results of ultrasound elastography, the average, minimum, and maximum shear wave velocities for enlarged LN in lymphoma (1st group) were 2.616 ± 0.684; 1.980 ± 0.557 and 3.351 ± 0.987 m / s, respectively; for LN with reactive changes (2nd group) – 1.704 ± 0.223; 1.414 ± 0.209 and 2.027 ± 0.261 m / s, respectively. Thus, the average, minimum, and maximum values of shear wave velocities significantly different between the groups (p ˂0.001). The cut off values of the average shear wave velocity in the differential diagnosis of lymphoma and hyperplasia are determined at the level of 2.05 m / s, with a sensitivity of 88.5 %, specificity of 100 %, and AUC of 0.942 (p ˂0.001).Conclusion. Ultrasound elastography demonstrated statistically significant differences in shear wave velocity in the enlarged superficial LN in lymphoma and in inflammatory processes that can be used as a preliminary non-invasive differential diagnosis of enlarged superficial LN in these conditions.

The objective: to evaluate the possibilities of ARFI technology (Acoustic Radiation Force Impulse), including Virtual Touch™ Tissue Imaging (VTI) and Virtual Touch™ Tissue Quantification (VTQ) for differentiation of lymphomatous and metastatic superficial lymphadenopathy.Materials and methods. The prospective study included 138 patients with enlarged superficial lymph nodes (LN). Based on a previous histological examination, patients were divided into two groups: 1st group (n = 108) – patients with non-Hodgkin’s lymphomas and Hodgkin’s lymphoma; 2nd group (n = 30) – patients with metastasis of solid tumors in superficial LN. All patients underwent ultrasound elastography of the enlarged LN using ARFI technology. In VTI study the Area Ratio parameter was evaluated, and the minimum and average values of the shear wave velocity were estimated in VTQ study.Results. According to the results of VTI study the Area Ratio parameter for enlarged LN in lymphoma (1st group) and for metastatic lymphadenopathy (2 nd group) were 1.031 ± 0.197 and 0.851 ± 0.15, respectively (p = 0.000009). The cut off value of the Area Ratio parameter was 0.901 with sensitivity, specificity and accuracy 80.6, 70.0 and 78.8 %, respectively. Minimum values of shear wave velocities for 1st and 2 nd groups were 1.980 ± 0.557 and 2.214 ± 0.367 m/s, respectively (p = 0.032). The cut off values of the average shear wave velocity in the differentiating of lymphomatous and metastatic lymphadenopathy are determined at the level of 2.00 m/s, with sensitivity of 70.0 %, specificity of 59.3 %, and accuracy of 61.6 %.Conclusion. Ultrasound elastography with ARFI technology demonstrated statistically significant differences in the Area Ratio parameter and in the minimum shear wave velocity in the enlarged superficial LN in lymphoma and with metastasis that can be used as a preliminary non-invasive differential diagnosis of enlarged superficial LN in these conditions. Moreover, the Area Ratio parameter has a statistically more significant effect on differentiating of lymphomatous and metastatic lymphadenopathy.
