Abstract
The aim of the study was to evaluate diagnostic accuracy of stress-echocardiography (stress-еchoCG) with combination of high doze dipyridamole and atrial pacing in diagnosis of late coronary shunts stenosis. 46 men aged from 42 to 63 (48,2 ± 1,8 years), 36 patients undergone mammarocoronary shunting, 10 patients undergone auto venous shunting. Stress-EchoCG with combination of high doze dipyridamole and atrial pacing suggested shunts lesions in 45 patients, in 7 cases previously intact coronary arteries, approved with coronary angiography. Coronary angiographies reviled no coronary lesions in 1 (3 %) patient, in 23 (50 %) patients > 70 % shunts restenosis, in 22 (47 %) coronary stenosis from 40 up to 70 %. Accuracy, sensitivity and specificity of stress-EchoCG with combination of stress-agents in coronary shunts restenosis, as well as stenosis of previously intact coronary arteries were 100 %.

Abstract
Tumors of the lateral ventricles and septum pellucidum are mostly benign, but total surgical resection can be a serious problem for neurosurgeons because of their deep location and the risk of developing intraoperative complications due to the high vascularization of some tumors. Routine MR study, including intravenous administration of a contrast agent, cannot predict high blood flow within tumors. The non-invasive method - ASL-perfusion is an informative tool, which can determine quantitative parameters of blood flow in intraventricular tumors and makes possible to identify a risk group for intraoperative blood loss.

Abstract
In present study were compared the technical characteristics and diagnostic performance of 64- versus 256-slice computed tomography coronary angiography (CTCA) in the detection of stenosis of coronary arteries ≥ 50 %, confirmed by conventional coronary angiography (CCA). Our study included 80 patients. In two similar populations, 256-slice CTCA displayed superior diagnostic performance than 64-slice CTCA. However, the performance of 256-slide CTCA is affected in those segments that are severely calcified and/or stented.

Abstract
One of the leading causes of hearing loss in the population is chronic otitis media (COM), in particular, complicated by cholesteatoma. Computed tomography remains the «first-line» technique in terms of diagnosing patients suffering from this disease. At the same time, the role of such a high-tech medical imaging method as magnetic resonance imaging becomes more important prior to surgical treatment planning . This review highlights the results of MRI usage in the diagnosis of chronic otitis media complicated by cholesteatoma.

Abstract
Lung cancer is a major medical and social problem during last few decades. Non-small cell lung cancer (NSCLC) is the most frequent type of lung cancer. Accurate clinical staging with assessment of locoregional tumor extension and distant metastases is crucial for treatment planning and assessment of patient prognosis. The article describes the current potential of cross-sectional imaging modalities for non-invasive diagnosis of mediastinal lymph nodes metastases in patients with NSCLC.

Abstract
Thrombosis of the internal carotid arteries in young people is an infrequent cause of cerebrovascular accident. The aim of the work is neuroimaging of a rare case of bilateral thrombosis of extracranial sections of the internal carotid arteries in a young woman. The presented results of radiation and laboratory studies demonstrate the need to take into account the possibility of bilateral thrombosis of the internal carotid arteries when conducting radiological studies in young patients with a stroke clinic.

Abstract
In neurosurgical practice of neurosurgery, a task-based functional magnetic resonance imaging (tb-fMRI) with motor and speech paradigms is a common method in preoperative planning lesion location around eloquent areas of the brain. This method can improve the surgical strategy with relevant information obtained non-invasively. But in majority of cases the results of tb-fMRI depend on the patient’s ability to follow instructions during study, which can be impaired due to brain tumor. When tasks cannot be performed by patient, the resting-state fMRI method (rs-fMRI) is more preferable. In this work, that is a part of the scientific project in assessment of neuronal activity in cases with brain gliomas of various localization, we present two cases of patients with glial tumors localized in the left hemisphere of the brain: frontal and temporal lobes with close proximity to Broca and Wernike areas. Based on a comparison of the results of tb-fMRT, rs-fMRT as well as direct cortical stimulation data, we propose a method for estimation the accuracy of coincidence in cortical activations obtained by three methods.
