Sirvanci M, Ganiyusufoglu K, Bhatia M, Ozturk C, Aksu N, Hamzaoglu A. Value of axial loading magnetic resonance imaging and computerized tomography-myelography in decision making in the treatment of degenerative lumbar spinal stenosis. Journal of Turkish Spinal Surgery. 2008; 19 (4): 417-426.Özet
Aim: The degenerative lumbar spinal stenosis (LSS) is a dynamic phenomenon. Changes in posture and physical activities as standing and walking can aggravate symptoms. The aim of the study was to evaluate the results of post axial loading Computed Tomography Myelography (CTM) versus Magnetic Resonance Imaging (MRI) in patients undergoing surgery for multilevel degenerative lumbar spinal stenosis. Methods: Thirty patients with multilevel degenerative LSS scheduled for elective surgery were enrolled in the study. Preoperatively, all patients underwent both MRI and CTM, in supine psoas relaxed position and post loading by axial compression in slight extension. Quantitative evaluation for LSS was conducted by two experienced radiologists. The parameters included dural sac cross sectional area, lateral recess and foraminal evaluations for stenosis, on CTM and MRI. Statistical analysis of the data was performed to evaluate relative advantages and additional information depicted by axial loaded CTM versus MRI Amaç: Dejeneratif lomber spinal stenoz (LSS) dinamik bir olgudur. Postüral değişiklikler ile ayakta durma ve yürüme gibi fiziksel aktiviteler semptomları ortaya çıkarabilir. Çalışmanın amacı, çok seviyeli dejeneratif LSS nedeniyle ameliyat edilen olgularda aksiyel yüklenme sonrası manyetik rezonans görüntüleme (MRG) ile bilgisayarlı tomografi-miyelografi (BTM) nin sonuçlarının karşılaştırılmasıdır. Yöntem: Elektif cerrahi için randevu verilen çok seviyeli dejeneratif LSS olan 30 hasta bu çalışmaya dahil edildi. Preoperatif olarak tüm hastalara supin pozisyonunda psoas kası gevşekken ve hafif ekstansiyonda uygulanan aksiyel kompresyon sonrasında MRG ve BTM çekilmiştir. Deneyimli iki radyolog tarafından LSS açısından kantitatif olarak değerlendirilmiştir. Parametreler, dural kese kesit alanı, lateral reses ve foraminal stenozun değerlendirmesini içermiştir. Verilerin istatistiksel değerlendirmesiyle aksiyel yüklenme ile yapılan BTM ve MRG tetkiklerinin göreceli avantajları ortaya konmuştur.
