[Ultrasound monitoring of consolidation processes in fractures of long tubular bones in osteosynthesis using bioactive implants].

Objective: To show the capabilities of ultrasound monitoring to assess consolidation processes in fractures of long tubular bones in the use of bioactive material-containing implants.

Material And Methods: Eighty-two (45.1%) patients whose bone fragments had been fixed with bioactive material-coated plates and 100 (54.

[Role of magnetic resonance imaging in the study of patients with diabetic foot syndrome].

Objective: To give the results of magnetic resonance imaging (MRI) in patients with complicated diabetic foot syndrome (DFS) to rule out or identify osteomyelitis.

Material And Methods: Twenty-seven (14 women and 13 men; mean age 60 ± 12.2 years) with type 1 and 2 diabetes mellitus and suspected osteomyelitis that had developed in the presence of DFS were examined.

[Different types of 199Tl chloride scintigraphic visualization of malignant tumors of the locomotor apparatus].

Background: 201Tl chloride scintigraphy allows malignant tumors of the locomotor apparatus to be diagnosed. The capacities of scintigraphy with 199Tl chloride, a 201Tl chloride analog, in addition to routine visualization of malignant tumors of the locomotor apparatus, have revealed its untypical variants.

Objective: to study the specific features of 199Tl chloride scintigraphic visualization of malignant tumor processes in the locomotor apparatus.

[Extrahospital pneumonias: the clinico-scintigraphic characterization and oxidative balance of cells].

Ventilation-perfusion pulmonary scintigraphy was carried out in 30 patients with a verified diagnosis of extra-hospital pneumonia (EHP) and 10 healthy subjects; ventilation-perfusion ratio (V/Q), apex-basis ventilation and perfusion gradient, and the condition of alveolar-capillary permeability (ACP) were analyzed. Clinical symptoms during the debut of EHP were more pronounced in patients with an alveolar type of pulmonary infiltrate (PI) vs. patients with interstitial one: they had pulmonary infiltration syndrome, pleural pain, tachypnoe, tachycardia, a fever of higher than 38 degrees C, and leucocytosis more often.

[Arthrosonography in the diagnosis of rheumatoid arthritis of the knee joint].

The paper presents the capacities of echography in the estimation of the activity of rheumatoid gonitis. A study of knee joints in 126 patients with rheumatoid arthritis has provided the basic ultrasound criteria that are characteristic for the first, second, and third degrees of its progression, which include the pattern of proliferative changes in the synovium, the qualitative and quantitative assessments of intraarticular exudate and its viscosity. The capacities of X-ray study and MRI in the detection of the progression of rheumatoid arthritis are discussed.

[Quantification of volume of tissue damage in stroke using T2- weighed MRI images].

We have developed a quantitative technique for scoring of the severity of ischemic damage of the brain using quantitative data of the T2-weighted MRI images of brain in stroke. The principle of the method is the assumption that T2 signal increases proportionally to the severity of ischemic damage of cerebral tissue up to the level equal to intraventricular liquor signal in the case of postinfarction cystic degeneration. Depicting the mean T2-signal from the intraventricular liquor region as Iliq, the signal from ischemic brain area as Iinsult, and from the intact brain as Inorm, obviously, the volume quota of damaged tissue in the total volume of the stroke region is represented by the ratio (Iinsult - Inorm)/(Iliq - Inorm).

[Morphological evaluation of modern diagnosis of osteomyelitis].

Current osteomyelitis diagnosis is based on detection of intraosseous abscess using radiopharmaceuticals--67Ga-citrate and 111In-citrin. Morphological examination confirms the presence of inflammation in the zone of local accumulation of radionuclide. A correlation was found between the degree of radionuclide absorption and phase of inflammatory process.

[Diagnosis of osteomyelitis using Ga-67 citrate].

To increase the specificity of radionuclide diagnosis of purulent bone affections the authors used Ga-67 citrate which is incorporated into the circulating leukocytes. From the results of examination of 32 patients a comparative characteristics of the diagnostic value of osteotropic agents labeled with Tc-99m and Ga-67 citrate are given. The expediency of using Ga-67 citrate for indicating an inflammatory process in the phase of abscess formation is shown.

[Complex radiodiagnosis of osteomyelitis].

In 23 patients with chronic osteomyelitis roentgenography of the bones and three-phase scintigraphy including radionuclide angiography, investigation of the soft tissues and bones were performed. In comparison of the data of clinical examination, roentgenography and radionuclide methods of diagnosis, the correspondence of the data of radionuclide angiography to the phase of an inflammatory process was established.
