SUPİN VE PRON POZİSYONLARDA SERİ MANYETİK REZONANS GÖRÜNTÜLEME İLE KONUS MEDULLARİS HAREKET ARALIĞININ ANALİZİ: 40 ARDIŞIK SAĞLIKLI İNSAN DENEKTE ELDE EDİLEN SONUÇLAR

Abstract

Amaç: Bu çalışmada seri halde supin ve pron pozisyonlarda T1 ve T2 ağırlıklı aksiyal ve sagital manyetik rezonans görüntüleme yapılan 40 sağlıklı insanda meduller konusun supin-pron pozisyon değişikliği ile uyarılan hareket aralığı değerlendirildi.

Yöntem: Her bir denekte konus medullarisin ucu seviyesinde elektronik ölçekler kullanılarak konus medullaris ve ön dural yüzey arasındaki mesafeyi ve dural kesenin genişliğini ölçtük. Elde edilen veriler SPSS 15 kullanılarak değerlendirildi. 

Bulgular: Konus ucunun, denekler supin pozisyondan pron pozisyona getirildiğinde ortalama değer olarak spinal kanal genişliğinin %30±14’ü oranında yer değiştirdiği saptandı (p:0,0001). Yaş (0-18 ve >19 yaş) ve cinsiyet farklılığı konus ucunun hareketliliğinde istatistiksel olarak anlamlı faktörler değildi. 

Sonuç: Çalışmamız klinik olarak gergin omurilik şüphesi bulunan normal uzanımlı konus vakalarında güvenilir bir diyagnostik referans aralığı sunmaktadır.

THE MOTION RANGE OF THE CONUS MEDULLARIS MOVEMENT WITH SERIAL MAGNETIC RESONANCE IMAGING IN SUPINE AND PRONE POSITIONS: RESULTS OF FOURTY HEALTHY SUBJECTS

Abstract

Objective: In this study, using a series of supine and prone positions T1 and T2 with weighted axial and sagittal magnetic resonance imaging, the movement interval of the conus medullaris stimulated by the supine-prone position change was assessed in 40 healthy subjects.

Method: We measured the distance between the conus medularis and the front dural surface and the width of the dural sac using electronic scales at the tip level of the conus medullaris in each subject. The data obtained was evaluated using SPSS 15. 

Results: It was determined that the spinal canal width was decreased by 30% (p:0.0001) as the average value when the conical tip was brought to the prone position from supine. Age (0-18 and >19 years) and gender diversity were not statistically significant factors in the movement of the conus medullaris. 

Conclusion: Our study offers a reliable diagnostic reference range in cases of normal extension conus with clinically tense spinal cord suspicion.
