[Mini-invasive interventions under magnetic resonance guidance in the clarifying diagnosis of small pelvic tumors].

Objective: To perfect and estimate the possibilities of using a mini-invasive diagnostic procedure under magnetic resonance (MR) guidance in the complex anatomic situations in cases of pathological small pelvic changes of unknown origin.

Material And Methods: Ten small pelvic interventions were made under MR guidance. The indications for bone biopsy under MR guidance were poor visualization of bone changes or their absence during radiography, including computed tomography.

[Solid tumors of internal female reproductive organs: comparison of the diagnostic efficiency of ultrasound study and magnetic resonance tomography].

Comparison of the diagnostic importance of traditional US and low-field MRI (0,23 T) in the characterization of solid tumors of internal reproductive system at 55 patients is performed by calculation of operational characteristics of tests and use of characteristic curves (ROC-analysis). Advantage MRI in distinguishing between of benign and malignant tumors (accuracy of 82% against 71% at ultrasonic) is established. Advantage is based on use, besides morphological criteria of a tumor, the characteristic of its MR-signal in T2-weight imaging.

[Magnetic resonance tomography in the staging of uterine neoplasms].

Diagnostic significance of MR imaging used for cervical carcinoma staging was established during the examination of 71 patients with verified tumors stage I-III. These findings were compared with the clinical and surgical data. MRI procedure proved highly effective in detecting uterine body involvement, identification of hydroureter caused by the ureters being squeezed by parametrial infiltrates as well as reliable exclusion of parametrial infiltration of bladder wall invasion.

[Reconstruction of vascular bed in the affected segment of the leg in patients with defects of the crural bones complicated by chronic osteomyelitis].

The article analyses the results of medical rehabilitation of 176 patients with defects in the leg bones complicated by chronic osteomyelitis by methods of transosseous osteosynthesis. In average hospitalization terms of 380.8 +/- 15.
