Vücut Kitle İndeksinin Epidural Yağ Mesafesi Üzerine Etkisinin Lomber Manyetik Rezonans Görüntülemede Değerlendirilmesi

Year 2018, Volume: 51 Issue: 2, 116 - 120, 29.08.2018

Abstract

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

Evaluation of the Effect of Body Mass Index on Epidural Fat Distance with Lumbar Magnetic Resonance Imaging

Year 2018, Volume: 51 Issue: 2, 116 - 120, 29.08.2018

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.
