摘要
目的探讨小视野(rFOV)扩散加权成像(DWI)对脊柱及脊髓病变的临床诊断价值。材料与方法对20名正常志愿者和33例脊柱及脊髓病变患者,行矢状面rFOV和常规FOV扩散加权成像,并邀请6名影像诊断医师对rFOV和常规FOVDWI序列信噪比和图像变形程度进行评估。结果 6名医师分别对53名受试者常规DWI和rFOVDWI图像信噪比及图像变形程度进行评价,显示所有受试者rFOVDWI信噪比及图像变形程度均优于常规DWI序列。结论与常规FOV扩散加权成像相比,rFOV扩散加权成像简便易行,具有高空间分辨率、高信噪比和变形小等优点,有助于脊柱及脊髓病变的诊断。
Objective： To discuss the usefulness of reduced FOV diffusion weighted imaging in spinal disease. Materials and Methods： Fifty-three objects （20 nonmal, 33 with spinal lesions）were scanned with rFOV-DWI and routine DWI. and the SNR and image distortion ratio about this two DW1 sequences were evaluated by two senior radiologists. Results： The SNR and image distortion ratio of rFOV-DWI are better than routine DWI. Conclusion： The rFOV-DWI can provides higher SNR and less distortion compared with conventional DWI. It can be easily performed, and is helpful in the diagnosis of spinal disease.
