【摘要】：目的研究颈髓高分辨弥散加权成像(DWI)的可行性及其在相关疾病中的诊断价值。方法对2015年1月—2016年12月127例怀疑颈髓病变的住院患者进行颈部MRI检查。扫描序列包括常规序列、常规DWI序列[基于单次激发平面回波成像(SS-EPI)技术]和高分辨DWI序列[基于分段读取平面回波成像(RS-EPI)技术]。比较不同疾病的常规DWI与高分辨DWI之间的图像质量评级,评估高分辨DWI对颈髓不同病变的诊断价值。结果 RS-EPI序列的图像质量显著优于SS-EPI序列(P0.05)。在不同病种中,RS-EPI序列的诊断价值不同,其在血管性病变中具有确切的诊断价值,在其他疾病包括脱髓鞘、炎性和肿瘤性病变中具有一定诊断价值,而在椎间盘性病变中的诊断意义不大。结论高分辨DWI序列在部分颈髓疾病中具有重要的诊断价值。
[Abstract]:Objective to study the feasibility and diagnostic value of high resolution diffusion-weighted imaging (DWI) in cervical spinal cord. Methods from January 2015 to December 2016, 127 inpatients with suspected cervical spinal cord lesions were examined with cervical MRI. Scanning sequences include conventional sequences, conventional DWI sequences [based on single-shot planar echo imaging (SS-EPI) technology] and high-resolution DWI sequences [based on piecewise read plane echo imaging (RS-EPI) technology]. To compare the image quality rating between conventional DWI and high resolution DWI in different diseases, and evaluate the diagnostic value of high resolution DWI in different lesions of cervical spinal cord. Results the image quality of RS-EPI sequence was significantly better than that of SS-EPI sequence (P 0.05). In different diseases, the diagnostic value of RS-EPI sequence is different, and it has definite diagnostic value in vascular lesions, and in other diseases, including demyelination, inflammation and tumor diseases. However, the diagnosis of intervertebral disc disease is of little significance. Conclusion High resolution DWI sequence has important diagnostic value in some cervical spinal cord diseases.
