Abstract |
To evaluat.e the diagnostic usefulness of quantitative
sacroiliac joint scintigraphy and its clinica1
significance in the ankylosing spondylitis, we measured
SIS ratio (Sacroiliac Joint/Sacrum Uptake ratio) by
region of interest method in 52 patients with
ankylosing spondylitis. As compared with radiological
grade, SIS ratio was significantly elevated in the
eariy stage of ankylosing spondylitis and returned to
normal range in the late stage. Scintigraphic finding
of focaI cptakes of radiotracer at multiple spinal
apophyseal joints was charactnistic and proximal large
joints were niore involved than distaI joints. The
incidence and extent of the arthropathy revealed by
scnitigraphy exceeded that which was clinically
evident, and scintigraphy was more sensitive to detect
syrnptomatic lesion than radiography. Therefore, it is
suggested that bone scan is useful for the early
diagnosis and the assessment of clinical activity of
involved joints of ankylosing spondylitis. |
