Abstract

Scintillation counting of the sacro-iliac bones using technetium pyrophosphate or diphosphate is a simple examination without danger. The uptake opposite each sacro-iliac bone is assessed by reference to that of the lumbar spine visible on the film. A study of a control group of 81 subjects permits one to determine the existence of variations in relation to age: the fixation is high in subjects under the age of 20 years and reduced in adults aged over 50 years. The 44 controls from 20 to 50 years, permit one to retain as reference value, the ratio 1.14 for the right sarco-iliac bone and 1.11 for the left sarco-iliac bone with a confidence interval of 0.13. There was noted a significantly high uptake during arthritis. Whether this was the axial form (40 cases) or the peripheral from (7 cases) and during Reiter's syndrome (15 cases). This hyperfixation was more frequent and more important when the sacro-iliac involvements (whether accompanied or not by radiological signs) were the cause of inflammatory pain. Increased uptake was also noted during other forms of chronic inflammatory rheumatism: rheumatoid arthritis (10 cases). Chronic inflammatory rheumatism (unclassifiable) 20 cases. It thus seems that one may retain in many case...Continue Reading
