Abstract

Objective: As it is known that the body mass index is associated with subcutaneous fat thickness, we aimed to investigate the effect of body mass index on epidural fat distance with lumbar magnetic resonance imaging.Methods: Lumbar MR images of the patients that performed for any reason were retrospectively reviewed and anterior, posterior epidural fat distances were measured at the level of L5-S1 vertebrae in sagittal T1 weighted images. Relation between epidural fat distances and body mass index obtained from height and weight values recorded before the examination, and also relation between epidural fat distances and subcutaneous adipose tissue thickness at the same level were investigated. Pearson correlation test was used in analysis of the data and p<0.05 value considered as statistically significant. Results: Total number of 542 patients, 342 female (63.1%) and 200 male (36.9%), were included in the study. The mean age± SD was calculated as 45.1 ± 14.5 years. According to body mass index patients showed a distribution as 14 (2.6%) underweight, 150 (27.7%) normal, 214 (39.3%) overweight, 118 (21.8% ) obese class 1 and 46 (8.5%) obese class 2. Subcutaneous adipose tissue thickness was measured 16.01±10.9 mm in underweight patients, 21.79±12.06 mm in normal patients, 28.46±13.34 mm in overweight patients, 39.16±15.78 mm in obese class 1 patients and 55.51±24.8 mm in obese class 2 patients. Anterior and posterior epidural spaces were found to be thicker in obese patients rather than in normal patients; respectively (4.46±1.65 mm vs 4.98±1.95 mm, p=0.014, 3.65±1.35 mm vs 4.06±1.48 mm, p=0.01). Conclusion: MRI is a very effective modality for the evaluation of epidural fat tissue and demonstration of other pathologies associated with epidural fat. Determination of hyperintense fat tissue around the hypointense dural sac can be easily performed on T1 MRI. Epidural fat tissue growth should also be considered next to degenerative diseases in the etiology in patients especially in obese who suffer pain, spinal cord and nerve root compression.

Özet

Amaç: Vücut kitle indeksinin subkutan yağ doku kalınlığı ile ilişkili olduğu bilinmekle birlikte biz bu çalışmamızda vücut kitle indeksinin epidural yağ mesafesi üzerine etkisini lomber MRG ile araştırmayı amaçladık.Yöntemler:Herhangi bir nedenle lomber MRG çekilmiş hastaların görüntüleri retrospektif olarak taranarak, sagittal plan T1 ağırlıklı görüntülerden L5-S1 vertebralar seviyesinden ön ve arka epidural yağ mesafesi ölçümleri yapıldı. Ölçülen değerler ile inceleme öncesinde kaydedilen boy ve kilo değerleri ile hesaplanan vücut kitle indeksi arasında bağlantı olup olmadığı; ayrıca epidural yağ mesafeleri ile aynı düzeyden ölçülen cilt altı yağ doku kalınlığı ile bağıntı olup olmadığı araştırıldı. Verilerin analizinde Pearson korelasyon testi kullanıldı ve p<0.05 değerleri istatistiksel olarak anlamlı olarak kabul edildi. Bulgular: Çalışmaya dahil edilen 542 hastanın 342'si (% 63.1) kadın ve 200'ü (%36.9) erkek idi. Ortalama yaş±SD değeri 45.1±14.5 yıl olarak hesaplandı. Vücut kitle indeksine göre hasta sayıları; zayıf 14 (%2.6), normal 150 (%27.7), kilolu 214 (%39.3), obez 1 grupta 118 (%21.8), obez 2 grupta 46 (%8.5) şeklinde dağılım göstermekteydi. Cilt altı yağ doku kalınlığı zayıflarda 16.01±10.9 mm, normallerde 21.79±12.06 mm, kilolularda 28.46±13.34 mm, obez 1'lerde 39.16±15.78 mm, obez 2'lerde 55.51±24.8 mm olarak bulundu.Çalışmada obezlerde normal kilolu olanlara göre ön ve arka epidural mesafe daha kalın bulundu; sırasıyla (4.46±1.65 mm vs 4.98±1.95 mm, p=0.014, 3.65±1.35 mm vs 4.06±1.48 mm, p=0.01). Sonuç: MR inceleme epidural yağ dokusunun değerlendirilmesi, eşlik eden diğer patolojilerin gösterilmesi açısından oldukça etkin bir yöntemdir. MRG'de T1 AG'de hipointens dural kese çevresinde hiperintens yağ dokunun değerlendirilmesi kolayca yapılabilmektedir. Özellikle obezlerde ağrı, spinal kord ve sinir kökü basısı olan hastalarda etiyolojide dejeneratif hastalıklar yanında epidural yağ doku artışı da göz önünde bulundurulmalıdır
