Therefore, the aim of the work was to evaluate the value of intravertebral fluid with osteoporosis and metastatic vertebral compression fractures using magnetic resonance imaging. Objectives of the study were to investigate: MRI semiotics of osteoporotic compression fractures with their diagnostic value; intravertebral fluid in pathological fractures.
Methods. 120 patients with pathologic compression fractures of the spine, which included 70 patients with acute osteoporotic and 50 - with metastatic, are examined. Among patients with osteoporotic fractures were 62 women (88.6 %) men - 8 (11.4 %) with an average age of 65.6 ± 11.1 years, and among patients with MCP fractures was 30 (60.0 %) men and 20 (40.0 %) women with a mean age 60.8 ± 12.5 years. All patients underwent an MRI on devices with a magnetic field strength of 0.2, 1.5 and 0.36 Tс (AIRIS Mate, ECHELON firm "Hitachi medical Corp.", Japan, "I-Open 0.36", China). Dual-energy X-ray absorptiometry (DXA) held 59 (39.1 %) patients. DXA was performed on the unit «Lunar PRODIGY Primo DHA"
Results. The basic structural and morphological changes with osteoporotic compression fractures of the spine such as - bone marrow edema, annular seal paravertebral soft tissue, compression of the veins bazivertebrales, remains of yellow bone marrow, involvement arches and rear elements of the vertebra, curved (intact) the back surface of the body, the fracture of the reflex plates, rear corner pieces with indicators of sensitivity, specificity, and accuracy. It was shown that the intravertebral fluid of the compressed vertebral bodies found in 72 (88.9 %) patients. This feature may also be an indicator of the seam (or splice) the data fractures.
Conclusions. Intravertebral fluid in the compressed vertebral bodies was found in 88.9 % of patients with osteoporotic fractures, and this feature can be another tool in the diagnosis of this category of fractures with high sensitivity, specificity and accuracy. This feature may also be an indicator of the seam (or splice) the data fractures. When metastatic compression fractures of this symptom is rare (6 %) and it is located mainly in the anterior body of compressed vertebrae
