464 patients were included to our study. The patients cohort was consist of: 214 female with histologically verified breast cancer (46,1 %); 51 patients with skin melanoma (11 %); head and neck cancers (except for thyroid cancer) were diagnosed in 123 patients (26,5 %) and thyroid cancer was revealed in 76 patients (16,4 %). The age of all patients was 19-76 y.o. (median - 57 y.o.). In all patients, metastatic changes were suspected in the different lymph nodes localization. According to the morphological examinations results, all patients of each malignancy were divided into two subgroups: with the proved lymph nodes metastases and with lymphoid tissue hyperplasia. The values of the Young's modulus for metastatic and hyperplastic lymph nodes were calculated in the each malignancy group. The Young's modulus values significant differences between metastatic and hyperplastic lymph nodes changes were revealed for all groups (p < 0,0001). The best levels of diagnostic efficacy (Se - Sp - AUROC) for the lymph nodes metastasis detection were achieved by the following cut-off: the breast cancer - ≥ 37,1 kPa (82,3-88,1-0,92); the skin melanoma - ≥ 22,7 kPa (86,0-76,9-0,91); the head and neck malignancies (except for the thyroid cancer) - ≥ 32,2 kPa (89,7-84,6-0,90); the thyroid cancer - ≥ 46,5 kPa (83,0-91,7-0,86).

The improvement of ultrasound diagnostics makes it possible to evaluate minor structural changes that were not previously available for reliable visualization. These include various diseases of the umbilical region, while the size of most pathological foci do not exceed 1-3 cm. Extensive experience with the neonatal contingent of patients allowed to highlight several groups of nosological forms that are rarely found in other age categories: infectious inflammatory lesions, abnormalities of umbilical ring formation, vascular and other lesions. Various echographic variants of visualization of the studied nosological forms are presented. Particular attention is paid to the imaging of infectious and inflammatory diseases that can echographically simulate cystic formations. The article is extensively illustrated and supplemented by a brief review of the literature.

The article presents a brief review of the literature and own clinical observations, summarizing our 5-year experience in diagnosing complications of kidney and ureter injuries. The study included 139 patients aged from 18 to 72 years old who were injured as a result of traffic accidents. All patients underwent conventional radiography of the thoracic and abdominal cavities, ultrasound and multislice computed tomography (MSCT) of the urinary tract. 17,3 % patients additionally underwent MRI. Considering the literature data and the results of our own research we recommend an MSCT scan, having the greatest diagnostic accuracy, for patients with polytrauma at different periods of the course of a traumatic disease, in order to more reliably detect damage of the kidneys and ureters as well as complications that have arisen, after a clinical and laboratory examination and an ultrasound scan. MRI of the kidneys and ureters is useful during periods of early and late manifestations of traumatic disease in order to detect renal complications, in cases when there is a discrepancy between clinical data, results obtained by ultrasound and MSCT, as well as for patients having contraindications for MSCT with intravenous contrast.

The article presents the modern trends of radiology development, demonstrates the features and the capabilities of different modalities in maxillofacial imaging. A technological outlook for planning and monitoring of treatment in dentistry and maxillofacial surgery is described. The aspects of development and implementation of advanced technologies are disclosed.

The possibilities of ultrasound examination in the diagnosis of soft tissue diseases of the maxillofacial region are shown. Marked by high informative value of sonography in the first stage of diagnostic search and in the differential diagnosis of pathological changes in the soft tissues of the head and neck.
