摘要
目的探讨全身MR弥散加权(WB-DWI)对全身淋巴结肿瘤性病变的应用价值。方法经病理证实淋巴结肿瘤性病变患者19例,1.5THDeMR进行全身MR-DWI轴位分段扫描,利用软件包将各段图像拼接重建呈全身图像。结果所有患者全身WB-DWI检查顺利,且全身WB-DWI对肿瘤淋巴结的显示较敏感。结论对全身淋巴结肿瘤性病变的诊断,全身弥散加权成像是一种快速、行之有效的技术,具有一定的临床价值。
Objective To investigate the potential of whole body diffusion weighted imaging in the diagnosis of lymph node lesions in patients with malignant tumors. Methods Whole body diffusion weighted imaging （WB-DWI） was used to scan 19 patients with histologically proven tumors on Signa Hde 1.5T scanner.A conventional MR coronal scan from head to inguinal region was used in segmental axial STIR-DWI scans, all images were reconstructed to whole body images by software. Results All lymph node lesions were clearly showed on DWI.Whole body MR-DWI was sensitive to lymph node lesions. But the image quality was not very good and increase of ghost occurred. Conclusion WB-DWI is a rapid and feasible method in detecting lymph node lesions and are of certain clinical value.
