Our goal in current work is to compare existing elastography technologies, provided by different ultrasound diagnostic devices manufacturers. The domestic technology «Elastografica», developed by authors also participated in the comparison. Every device that took part in the comparison was tested with the same masses of breast elastography phantom. We focused on evaluating physical properties of investigated objects.

The purpose of this study is improvement of diagnostics of the colon diseases and increase the effectiveness of radiographic method in the evaluation of patients coloproctological profile in terms of pneumatosis of the colon. The research is based on 149 patients with various complaints from the gastrointestinal tract. Here were 37 (24,8 %) men and 112 (75,2 %) women among them, ranging in age from 17 to 84 years. In the colon of all patients was determined significant amount of air from the previously performed endoscopy. At colonoscopy the examine of 116 patients colon wer realized just before the rectum and sigmoid colon. The main reason for the impossibility of endoscopic examination is soreness and psychological intolerance to the procedure was detected in 69 (53,5 %) patients, including due to rigid fixation of the distal colon in 40 (31 %) patients. After a barium enema performed by a special technique was evaluated the necessity and possibility of performing Х-ray examinations of the colon in patients directly after the survey with the introduction into the colon of gas media. By results of work it is established that performance of x-ray examination of the colon immediately after incomplete colonoscopy possible, and in some cases even necessary, for the purpose of diagnosis or differential diagnosis of diseases of the colon. And also it was conducted a comparative assessment of the effectiveness of traditional and new barium enema x-ray technique in patients after the colonoscopy, which accourding for 87 and 97 %.

The purpose of this study was to evaluate the functional parameters of the left ventricle (LV) in patients with coronary heart disease (CHD) before and early after surgical revascularization using standard echocardiography and Velocity Vector Imaging. The study included 28 patients with ischemic heart disease. Based on the evaluation of the contractile function of the left ventricle during a standard echocardiographic examination at rest were divided into two groups: group I — without contractile dysfunction (n = 14), group II with impaired contractility (n = 14). The impact of CHD on LV segments in both groups is reflected not only in combined compensatory decrease or increase of strain (S) and strain rate (SR), but also variations due to changes mainly of S or SR. Along with this marked change in the direction of motion of LV myocardial fibers. After revascularization more expressed positive dynamics of the functions of longitudinal fibers identified in group I. A significant improvement of radial fiber function were recorded in both groups. Significant dynamics in the function of circular fibers in the early stages are not registered.

Alveococcosis liver is a parasitic disease, the diagnosis of which is the difficulty in similarity with malignant tumors of the liver due to infiltrative growth, the possibility of metastasis and high relapse rate after surgery. It evaluates the current possibilities of ultrasound and CT diagnosis liver alveococcosis, including opportunities of elastography (ARFI) in the differential diagnosis of alveococcosis and primary liver cancer. To optimize radiation diagnosis of this disease the authors studied ultrasound and CT-signs in 28 patients examined, operated and followed up for 7 years in a specialized Hepatology Center.

A rare clinical observation: pathological artheriomesocaval bypass in a child with portal cavernoma, portal hypertension is presented. The features of ultrasound visualization of shunt, his differential-diagnostic criteria are discussed. The child was successfully operated: the separation of the shunt was performed. The results of the sonography and different ray research methods and the short review of the literature is present.

The presented case report shows the abilities of intravenous urography (IVU) and computed tomography urography (CTU) in the diagnosis of ureteral abnormalities, such as ureteral strictures. Both methods provide important diagnostic information, CTU allows volume visualization with the help of 3D-reconstruction technique and is recommended by European Guidelines of Urology as a method of choice for study of the upper urinary tract.
