Abstract<br /> Introduction. The development of diagnostic imaging facilitates evaluation of spinal anatomy, but there is no full correspondence between morphologic and pathologic changes observed in radiographic studies and clinical findings.<br /> The aim of the study was to:<br /> 1. Evaluate the degree of signal intensity and degenerative changes of intervertebral discs in the lumbar spine on MRI.<br /> 2. Estimate interrater reliability of classification of pathology between experienced and inexperienced medical doctors. <br /> Material and method. The sample consisted of 89 persons aged between 18 and 21 years. MRI scans of the lumbar spine were evaluated by the use of a console for digital analysis by three medical doctors with different levels of experience. <br /> Results<br /> Evidence of dehydration of intervertebral disc was found in 3.37%-4.49% at the L4-L5 level, and in 13.48%-15.73% of cases at the L5-S1 level. Interrater reliability ranged from full agreement at levels where degenerative changes are rarely observed to fair and poor agreement at L4-L5 and L5-S1. Intrarater reliability showed full agreement on higher levels to good and very good at l4-l5 and l5-S1 levels. <br /> Interrater reliability concerning the degree of degenerative changes was 0.6 for Th12 to L4, but was poor at L4-L5 and L5-S1. Intrarater reliability ranged from full agreement at higher levels to poor at L3-L4-L5 and moderate at L5-S1. <br /> Conclusions:<br /> 1. Asymptomatic intervertebral disk changes were found in 30% of the study participants.<br /> 2. Evaluation of the degree of degenerative changes of intervertebral discs requires specialist training and experience.<br /> <br /> |
