双能量CT诊断颈椎间盘退变及突出症的价值
The value of dual-energy CT in cervical intervertebral disc degeneration and herniation
摘要
Abstract
Objective:To assess the feasible of Rho/Z value derived from dual-energy computed tomography(DECT)in cervical disc degeneration(CDD)and herniation.Methods:MRI and DECT imaging data of 50 patients with neck back pain were included.All discs were classified on the basis of Pfirrmann grading system.Rho value of nucleus pulposus were measured and the variances in different grades and different disc level were analyzed with one-way ANOVA test.Correlations between Rho value and grades were analyzed with Spearman correlation test.MRI as the reference standard,the sensitivity,specificity,PPV,NPV and accuracy of conventional grayscale CT images and dual-energy color-coded reconstructed images in the detection of cervical disc herniation were compared.Results:The Rho value of nucleus pulposus in cervical intervertebral disc increased with the increase of Pfirrmann grade and decreased with the decrease of segmental position,and the difference was statistically significant(P＜0.001).There was a moderate positive correlation between Rho value of nucleus pulposus and Pfirrmann grades(r=0.584,P＜0.05).Dual-energy color-coded reconstructed images had higher overall sensitivity(86.7％vs 74.3％),specificity(90.2％vs 79.3％),PPV(96.7％vs 92.3％),NPV(66.9％vs 48.0％)and accuracy(87.5％vs 75.5％)in detecting cervical disc herniation compared conventional grayscale CT images.Conclusions:The color-coded reconstruction image of DECT can significantly improve the diagnostic accuracy of cervical disc herniation,and the Rho value of nucleus pulposus is associated with the degree of intervertebral disc degeneration.关键词
