[Normal and pathological structural features of lacrimal gland based on spatial ultrasound digital examination].

For the first time vital morphological structure of lacrimal gland was investigated based on spatial ultrasound digital examination. Structural characteristics of lacrimal gland are described considering anatomic topography and blood supply. These characteristics are analyzed based on planar and volumetric sonography depending on the patient age and pattern of changes.

[Study of the capacities of magnetic resonance imaging in the diagnosis of knee joint injuries].

Joint injury is presently one of the main causes of temporary disability of an economically and socially active population. The precise preoperative diagnosis enables the planning of adequate surgical intervention, reduction of the time of disability, and improvement of quality of life. However, magnetic resonance imaging (MRI) most commonly performed in patients with knee joint injury shows a high variability in diagnostic efficiency.

[Ultrasound spatial clinical analysis of the orbital part of the lacrimal gland in health].

The paper presents an algorithm of ultrasound spatial analysis of the unaltered lacrimal gland. The algorithm has been used to define its shape, size, density, structural features and the pattern of blood supply, as well as the anatomic and topographic position in the orbit. The study was conducted in the B- and 3D-modes of color and energy Doppler mapping on both sides.

[Spatial ultrasound visualization of the eye and orbit].

The paper presents data on the diagnostic use of three-dimensional (3-D) ultrasound visualization, analyzes earlier existing and new ultrasound diagnostic technologies, and shows it expedient to apply them in ophthalmologic practice. A hundred and forty-six healthy individuals and 52 patients (60 eyes) with different diseases of the eye and orbital cavity (chorioidal melanoma, facial angiomatosis, retinal detachment, vitreoretinal changes, etc.) were examined.

[2. Diagnostic resources and clinical indications].

Preliminary investigations, dedicated to the diagnostic application of three-dimension ultrasonic angioreconstruction, confirmed the feasibility of using the above method in ophthalmologic practice in cases of suspected intraocular and orbital neoplasms. 32 patients (37 eyes) with various pathologies of the eye and orbital cavity, including choroidal melanoma, facial angiomatosis, retinal detachment, chronic uveitis etc.) were examined.

[Three-dimensional computerized sonography in evaluation of the vascular system of the eye and orbit. I. Methodological approach and principles of analysis of results].

An examination of 40 healthy persons (80 eyes) enabled a refinement and unification of the ultrasound techniques applicable to investigations of a. ophthalmica, a. and v.

[Ultrasound angiography: new perspectives in diagnosis of renal mass lesions].

Aim: To evaluate diagnostic efficacy of advanced ultrasound (US) techniques in early and differential diagnosis of malignant tumors of the kidneys.

Material And Methods: A total of 394 patients with renal mass lesions were studied. They had: renal cell carcinoma (n = 96), renal parenchyma pseudotumors (n = 22), lipoma (n = 48), angiomyolipoma (n = 19), renal abscess (n = 2), renal sinus lipomatosis (n = 1), parenchymal cysts (n = 205), retroperitoneal leiomyosarcoma with invasion in the kidney (n = 1).

[Diagnosis of bladder cancer].

Increasing incidence of bladder tumors necessitates development of new techniques of early diagnosis. A total clinical system including application of ultrasonoangiography proved superior to examination under the gray scale mode. The diagnostic and monitoring algorithm makes the system highly effective.

[Conservative surgery of renal cancer].

Organ-preserving technologies are coming up to take the place of organ-removing operations for cancer of the kidney. A tumor size is not a decisive parameter any more as the decision is made in each individual case. Ultrasound, as a screening test, has changed the situation in the diagnosis of early stages of the disease, but routine urological examinations retain their importance.
