title: [Methodological problems of sacroiliac joint scintigraphy (author's transl)].
abstract: Bone scintigraphy of the sacroiliac joints and the lumbar spine was performed in 35 patients with ankylosing spondylitis and 30 control subjects. The scans were evaluated by qualitative and quantitative assessment. The sacroiliac/sacrum ratio (index ISG/sacrum), the sacroiliac/lumbar spine ratio (index ISG/LWS), and the left sacroiliac joint/right sacroiliac joint ratio (index li. ISG/re. ISG) were calculated. The visual interpretation of colour scans proved to be unreliable. The index ISG/sacrum was more sensitive than the index ISG/LWS. The index li. ISG/re ISG was helpful as an additional criterion. When digital sacroiliac joint scintigraphy is well standardized it can be considered as a useful technique in early diagnosis of ankylosing spondylitis.
