AbstractQuantitative magnetic resonance imaging (relaxation time and proton density measurements) has gained increasing interest as a noninvasive way to study changes in water content and biochemical composition of lumbar intervertebral discs and vertebral bodies. This article reviews the current methodological problems and the feasibility of quantitative magnetic resonance imaging in the lumbar spine for investigations on water content and biological composition. This technique does not allow direct quantification of water content. Although biochemical variations may sensitively influence relaxation times and proton density under in vitro conditions, it is not feasible to obtain sufficiently reliable and specific information to monitor biochemical alterations associated with lumbar disc pathology in vivo.
