[In vitro differentiation of inflammatory and non-inflammatory states of the synovial fluid by magnetic protonic relaxation].
The differentiation between inflammatory and non inflammatory states has been performed using Nuclear Magnetic Resonance (NMR) in vitro by measuring relaxation times T1 and T2 in 84 synovials fluids obtained from various rheumatologic diseases. The results show that the T1/T2 ratio is more sensitive to distinguish these two situations rather than the isolated T1 or T2 values. In particular, high values of T1/T2 ratio are found in septic arthritis.
