Abstract

PURPOSE:To image the cervical spinal nerves directly in patients with clinical and radiographic evidence of cervical radiculopathy via high resolution MR neurography by means of a qualitative and quantitative analysis. MATERIALS AND METHODS: Twenty symptomatic patients with cervical radiculopathy and five asymptomatic volunteers were examined. A phased-array coil system was used to obtain high-resolution coronal T1-weighted spin echo and coronal/axial short tau inversion recovery (STIR) images of the cervical spine and spinal nerves. On the axial STIR images, nerve/muscle signal intensity ratio of the cervical spinal nerves were measured on both sides and compared with paired samples t test. P values below 0.05 were considered statistically significant (p< 0.05). RESULTS: A markedly increased signal in the distal portion of the affected spinal nerves was found. Nerve/muscle signal intensity ratio measurements of the affected spinal nerves showed a significantly increased intensity compared with the noninvolved spinal nerves (p< 0.05). In controls, nerve/muscle signal intensity rate was nearly identical on both sides (p> 0.05). CONCLUSION: Magnetic resonance neurography performed with phased-array coils can detect signal abnormalities within compressed cervical spinal nerves in patients with corresponding radicular symptoms and findings. This technique may be helpful especially in evaluating patients with multi-level disc disease of the cervical spine.

Özet

AMAÇ Klinik ve radyografik olarak servikal radikülopati bulguları olan hastalarda servikal spinal sinirleri yüksek rezolüsyonlu MR nörografi ile direkt görüntülemeyi ve hem nitel hem de nicel yöntemle incelemeyi amaçladık. GEREÇ VE YÖNTEM Semptomatik servikal radikülopatili 20 hastaya (25-48 yaş, ortalama= 32.4 yaş) ve 5 gönüllü asemptomatik olguya (31-43 yaş, ortalama= 34 yaş) MR nörografi uyguladık. Yüzeyel sargı kullanarak uyguladığımız MR nörografi protokolümüz; yüksek çözünürlüklü koronal T1A SE, koronal ve aksiyel planda short tau inversion recovery (STIR) sekanslarından oluştu. Aksiyel plandaki short tau inversion recovery görüntülerinde servikal spinal sinir köklerinin ve kasın sinyal intensitesini çift taraflı ölçerek, sinir/kas sinyal intensite oranı saptandı ve bağımlı örnekler-t testini kullanarak bilateral servikal sinir köklerine ait sinir/kas sinyal intensite oranı karşılaştırıldı. Etkilenen servikal spinal sinirlerin distalinde belirgin sinyal intensite artışı gözledik. Hasta grubunda etkilenen servikal spinal sinir/kas sinyal intensitesite oranının simetriğine göre istatistiksel olarak anlamlı yüksek olduğunu saptadık (p 0.05). SONUÇ Kanımızca yüzeyel sargı kullanarak uyguladığımız MR nörografi yöntemi radiküler semptom ve bulgular ile uyumlu servikal spinal sinir köklerindeki sinyal intensite değişikliklerini görsel ve ölçümsel olarak belirlememizi sağlayabilmektedir. Bu yöntem servikal radikülopatili hastaların doğru tanı ve tedavisindeki başarıyı arttırabilir.
