Spondiloartritli hastalarda sakroilietin saptanmasında sintigrafinin tanısal değeri net değildir. Amacımız klinik olarak olası spondiloartritli hastalarda sakroilietin saptanmasında farklı yöntemlerle yapılan kemik sintigrafisinin tanısal değerini değerlendirmektir. Klinik olarak sakroiliak hastalığı olan 37 hastaya sintigrafik, laboratuvar ve radyografik inceleme yapıldı. Kontrol grubu olarak 81 olgunun kemik taramasının kantitatif analizi dahil edildi. Kemik sintigrafisi 99mTc-MDP düzlemsel görüntüleme ve tek foton emisyonlu bilgisayarlı tomografi (SPECT) kullanılarak yapıldı. Düzlemsel görüntülerde tüm ve kısmi sakroiliak eklem ile sakrum arasındaki oranlar ölçüldü, ek olarak SPECT görüntülerinde sakroiliak eklem ve ilium oranı hesaplandı. Klinik bulgular referans kriter olarak kullanılarak sintigrafik parametrelerin tanısal doğruluğu değerlendirildi. Düzlemsel görüntülemenin duyarlılığı ve özgüllüğü % 53 ve % 64 olarak tespit edildi. Eklemin alt kısmına ait oran kullanıldığında duyarlılık ve özgüllüğün az miktarda arttığı saptandı. SPECT ile bulunan duyarlılık ve özgüllük değerleri (% 77 ve % 86), düzlemsel yöntemlerde bulunanlardan daha yüksek olarak bulundu. Kontrol grubundaki sakroiliak eklem / sakrum oranı (Sİ/S) oranları hem sağ-sol eklemler arasında hem de her iki cins arasında farklılık göstermedi, ancak her iki cinste yaşla birlikte belirgin azalma saptandı. Çalışmanın sonucunda sakroiliak eklem kantitatif kemik sintigrafisinin sakroileit tanısı için sınırlı bir değerinin olduğu bulunmuştur. Ayrıca, SECT sakroileit tanısında düzlemsel kemik sintigrafisinden daha iyi duyarlılık ve özgüllük göstermektedir.
In patients with spondylarthritis, the diagnostic value of syntigraphin in the detection of sacrality is not clear. Our goal is to evaluate the diagnostic value of bone syntigraphy performed by different methods in the detection of sacrality in clinically possible patients with spondylarthritis. 37 patients with clinically sacroiliac disease were submitted to syntigraphic, laboratory and radiographic examinations. The control group included a quantitative analysis of the bone scan of 81 incidents. The bone syntigraphy was made using 99mTc-MDP flat imaging and single photon-emitted computer tomography (SPECT). In parallel images, the proportions between the whole and partial sacronic joint and sacrum were measured, in addition, in SPECT images, the sacronic joint and the iulium proportion were calculated. Clinical findings used as a reference criterion to evaluate the diagnostic accuracy of syntigraphic parameters. The sensitivity and peculiarity of the flat-screen view was identified at 53% and 64%. When the ratio of the lower part of the joint was used, it was found that sensitivity and personality increased a small amount. The sensitivity and specificity values found with SPECT (77% and 86%) were higher than those found in flat-scale methods. In the control group, the sacroilial joint/sacrum ratio (SI/S) ratio did not differ between both right-left joints and between both genes, but a remarkable decrease was observed in both genes with age. The study found that the sacrolithic joint quantitative bone syntigraphy has a limited value for the diagnosis of sacrolith. Furthermore, SECT shows better sensitivity and peculiarity in the diagnosis of sacrolitis than flat bone syntigraphy.
The diagnostic value of scintigraphy in the detection of sacroiliitis in patients with spondyloarthritis is unclear. Our aim is to evaluate the diagnostic value of bone scintigraphy that is done by different methods in detecting sacroiliitis in patients with clinically possible spondyloarthritis. Thirty-four patients with clinically sacroiliac disease underwent scintigraphic, laboratory and radiographic examinations. Eighty-one subjects were also included as a control group for quantitative analysis of the bone scan. 99mTc-MDP bone scintigraphy was performed using a planar imaging and single photon emission computed tomography (SPECT). In the planar images, the ratios between the whole and partial sacroiliac joint and the sacrum were measured, in addition, the sacroiliac joint and ilium ratio was calculated in the SPECT images. Using the clinical signs as the reference criterion, the diagnostic accuracy of the scintigraphic parameters was assessed. The sensitivity and specificity of planar imaging were 53% and 64%. When we used the ratio of the lower part of the joint, sensitivity and specificity were slightly increased. The sensitivity and specificity values (77% and 86%) of SPECT were higher than that found in planar methods. The sacroiliac joint / sacrum ratio (SI/S) in the control group did not differ between the right-left joints and between both sexes, however, there was a marked decrease with age in both sexes. As a result of the study, it was found that sacroiliac joint quantitative bone scintigraphy has a limited value for the diagnosis of sacroiliitis. In additon, SPECT shows better sensitivity and specificity than planar bone scintigraphy in the diagnosis of sacroiliitis.
