The aim of this study was to assess the concordance between magnetic resonance imaging (MRI) grading for cervical neural foraminal stenosis (CNFS) based on axial and oblique sagittal images and evaluate the reliability of each grading plane. CNFS was graded at C2-3 to C7-T1 levels based on axial and oblique sagittal images separately by three radiologists. The concordance between CNFS grading based on axial and oblique sagittal images was strong for all three observers (Kendall's W=0.80, 0.79, and 0.82), despite the tendency of higher grading with oblique sagittal images. Both imaging planes supported strong interobserver reliability.
本研究的目的是评估基于轴向和斜矢状位图像的颈椎神经孔狭窄(CNFS)磁共振成像(MRI)分级之间的一致性,并评估每个分级平面的可靠性。三位放射科医生分别根据轴向和斜矢状位图像在C2-3至C7-T1水平对CNFS进行分级。尽管斜矢状位图像有更高分级的趋势,但对于所有三位观察者而言,基于轴向和斜矢状位图像的CNFS分级之间的一致性都很强(肯德尔W系数分别为0.80、0.79和0.82)。两个成像平面均支持观察者间的高度可靠性。
