The aim of the study was to prospectively validate MR-criteria used for diagnosis of trigeminal neuralgia (TN). Study population consisted of 133 patients: with trigeminal neuralgia (TN) (86, surgically (n = 56) and clinically (n = 30) verified; 55 ± 11 years) and reference group (47; 51 ± 16 years). The data were obtained using the FIESTA sequence (slice thickness 0,5 mm) on 3 T and 1,5 T (Discovery 750w and Optima 450w, General Electric). Oblique coronal submillimetric reformatted images from MR-3D datasets were used to determine the length, cross-sectional area (CSA) and diameters ratio (DR, ratio of the biggest cross-sectional diameter to the smallest) of the trigeminal nerves at the point of 5 mm from the pons. The CSA on the symptomatic side were significantly smaller than the CSA on the asymptomatic side in outpatients with neuralgia (medians 2,9 and 4 mm2, p < 0,05) and operated patients (medians 2 and 3,38 mm2, p < 0,001). Also the mean CSA on the symptomatic side was significantly smaller in comparison with the controls (medians 2,3 and 3,55 mm2, p < 0,001). The DR on the symptomatic side were significantly bigger than the DR on the asymptomatic side in outpatients (medians 1,78 and 1,32; p < 0,001) and in operated patients (medians 2,1 and 1,43; p < 0,001). The DR on the symptomatic nerves were significantly bigger in comparison with the controls (medians 2,08 and 1,4; p < 0,001). The lengths in collateral nerves in patient with TN (medians 12,4 and 11,9 mm, p > 0,05 for outpatients; medians 12,9 and 12,6 mm, p > 0,05 for operated patients) and in comparison with the controls were not statistically different (medians 12,55 mm and 12 mm, p > 0,05). The CSA in outpatients with TN were significantly bigger than the CSA in operated patients (medians 2,9 and 2 mm2, p < 0,05). DR in outpatient and operated patients did not statistically differ (medians 2,1 и 1,78; p > 0,05). Thus, noninvasive MR-measurements of the trigeminal nerves show the differences between the symptomatic and asymptomatic side in the patients with TN as well as healthy individuals. This result may be used in the diagnosis of TN.

The aim of the study was to determine, with the help of comparison between patient complaints and magnetic resonance imaging (MRI) findings of temporomandibular joint (TMJ), whether the reason of pain is displacement of articular disc. Dysfunction of TMJ combines various clinical conditions caused by internal disorders of TMJ, muscular disorders as well as biomechanical disorders of TMJ. The most striking manifestation of the TMJ dysfunction are orofacial pain. The gold standard for diagnosis of TMJ dysfunction is MRI. Included in the study 150 patients with diagnosis of "TMJ dysfunction". In this study, were interpreted correlation between the presence of pain and the presence of any type of disc displacement, taking into account the pain sensation and disorders. According to the statistical analysis, there is weakly positive correlation between displacement of articular disc and pain sensation in the TMJ. We showed that articular disc displacement is not the immediate cause of pain.

The article is based on the results of perfusion computed tomography of the liver in patients with obstruction of the biliary tract of various origins. All patients were divided into 3 degrees of severity of hepatic failure. It is shown that depending on the severity of liver failure, consistently there is a decrease in perfusion of the liver. The data of the research results.

The article considers requirements to X-ray units intended for use in pediatric imaging. Medical and technical requirements which can be applied for developing a dedicated pediatric X-ray unit or a series of units are defined based on the regulatory research and a radiologists' survey. The requirements proposed in the article include specifications for X-ray tubes, power supplies and detectors, image post-processing requirements, and recommendations on positioning and restraining devices for the smaller patients. The article also considers a number of technological measures for minimizing patient X-ray exposure in pediatric imaging.

Analyzed CT and MRI studies with intravenous contrast enhancement (ICE) performed in municipal ambulatory-care clinic in Moscow in 2016 and the first half of 2017. Data were included in the analysis for 64 slices CT (52 scanners), 1,5 T MRI (36 scanners), connected to a common radiological service (ERIS). All scanners are equipped with two-syringe injectors. Positive experience of CT and MRI with ICE administration was noted in the example of Moscow. That allows to recommend these methods for wider introduction in the other regions of the country.

Every year there is the appearance of new terms, which complicates the work of doctors. Abroad, there are multiple dictionaries and glossaries, which are precise definitions of many words. In our literature there are multiple versions of the descriptions of the same state. And this problem exists not only with new terms. This review focuses on such terms as the «nodule» and «mass» and phrases associated with them.

The article describes the possibilities of the X-ray method in the diagnostic search for diseases of the thorax in patients observed in the Department of Thoracic Surgery Moscow Clinical Municipal Children Hospital St. Vladimir, Department of Health Care of Moscow. Are presented the use of computed tomography (CT) with bolus contrast for the detection of a rare organ pathology of chest in children ̶ the anomaly of the bronchopulmonary system and the formation of the mediastinum.

Nowadays most experts who follow the modern global medical community trends are aware of the English language knowledge necessity at a basic level at least. The lack of the unified terminology, the multiple items of the same concepts, lots of obsolete terms, incorrect spelling, pronunciation of eponyms especially - all these things are the problem of Russian medical language as well. These factors combination was account the basis for the publications series creation entitled «English Terms Glossary» for the «Radiology - practice» journal, which will be published in subsequent issues.
