Assessment of trabecular bone structure with magnetic resonance T2 relaxation time in osteoporosis

Öz:

Amaç: Bu çalışmada, osteoporozda kemik mikromimarisinin kantitatif olarak değerlendirilmesinde Manyetik Rezonans Görüntüleme (MRG) yönteminin kullanılabilirliğini ve MRG yöntemi ile dual enerji x-ray absorpsiyometri (DXA) yöntemi arasındaki korelasyonu araştırmayı amaçladık. Gereç ve Yöntem: Çalışmamıza 31 postmenopozal osteoporotik kadın ve 31 postmenopozal normal kemik mineral yoğunluğuna (KMY) sahip sağlıklı birey alındı. Ölçümler DXA ile omurga ve femurdan yapıldı. MRG T2 relaksasyon zamanı (T2 RZ) ölçümleri lomber 3 (L3) vertebra ve kalkaneusdan yapıldı. Postmenopozal bireylerdeki L3 vertebra DXA sonuçları L3 vertebra T2 RZ ve kalkaneus T2 RZ ölçüm sonuçları ile karşılaştırıldı.Bulgular: L3 vertebra ve kalkaneus T2 RZ ölçümlerinde osteoporotik ve normal KMY’ye sahip postmenopozal kadınlar arasında anlamlı fark saptandı (p<0,001). L3 vertebra KMY’si ile L3 vertebra T2 RZ ve kalkaneus T2 RZ arasında negatif korelasyon vardı. L3 vertebra T2 RZ ve kalkaneus T2 RZ arasında ise pozitif korelasyon saptanmıştır. Sonuç: DXA sonuçları ile T2 RZ yöntemiyle yapılan MRG sonuçlarının korele olduğu tespit edilmiştir. Trabeküler kemik yapısının değerlendirilebildiği MR T2 RZ ölçümleri ile postmenopozal osteoporotik ve sağlıklı bireylerin ayırımının mümkün olabileceği sonucuna varılmıştır.

Objective: This study was planned to investigate the utility of Magnetic Resonance Imaging MRI in assessing osteoporosis in a quantitative manner by evaluating bone micro architecture and to assess the correlation between MRI measurements and dual energy X-ray absorptiometry (DXA).Materials and Methods: The study group consisted of 31 postmenopausal osteoporotic women and control group consisted of 31 healthy postmenopausal women with normal bone mineral density (BMD). BMD measurements were performed with DXA at spine and at femur. The MRI T2 relaxation time (T2 RT) measurements were performed at lumbar 3 (L3) vertebra and calcaneus. The results of L3 vertebra DXA measurements of the postmenopausal subjects were compared with L3 vertebra MRI T2 RT and calcaneus T2 RT. Results: There was a significant difference between postmenopausal women with normal BMD and those with low BMD regarding the T2 RT of L3 vertebra and calcaneus (p<0.001). We found a negative correlation between L3 vertebra BMD and L3 vertebra T2 RT and calcaneal T2 RT. There was a positive correlation between L3 vertebra T2 RT and calcaneal T2 RT. Conclusion: The MRI results obtained by this technique were found to be correlated with the DXA results. It seems to be possible to discriminate postmenopausal osteoporotic and healthy women with MR T2 RT which assess trabecular bone structure. Turk J Phys Med Rehab 2008;54:50-3
