Bone mineral density is an important parameter that determines strength of the bone. Decrease in bone mineral density (BMD) leads to dangerous skeletal diseases like osteopenia, osteoporosis and an increased risk of fractures, for instance compression vertebral fracture (CVF). Dual-energy x-ray absorptiometry (DXA) and quantitative CT (QCT) are commonly accepted methods for assessing of the BMD. Previously FF was shown to increase in adult patients with osteoporosis as compared to healthy volunteers. The aim of the study was to explore the relationship between FF and BMD in children. Correlation analysis revealed significant inverse correlation link (p1H MRS could be good alternative to QCT and DXA without radiation dose in osteoporosis detection. Revealed significant negative correlation between FF and BMD in children without osteoporosis suggests that the processes of increasing FF in the bone marrow and lowering the BMD are parallel. Therefore, 1H MRS could be good alternative to QCT and DXA without radiation dose in osteoporosis detection.

The aim of this study is to elucidate the effect of one HBO session on the concentrations of metabolites detectible by 1H and 31P magnetic resonance spectroscopy. An activation of energy metabolism that manifested in the decrease of creatinephosphate (PCr), pHint and increase α-ATP signal after a HBO session is revealed. Other ATP resonances remain unchanged. Also the reduction of N-acetyl aspartate by 3% in mediolateral prefrontal cortex (MPFC) with p2.
