目的：探讨磁共振全身弥散加权成像技术（WB-DWI）对恶性肿瘤全身转移及寻找原发灶的临床应用价值。方法对80例健康志愿者和23例已知转移瘤寻找原发病灶以及85例发现原发肿瘤探查有否全身转移灶行全身WB-DWI 检查。结果80例健康志愿者均未发现恶性病变。108例肿瘤患者中，23例已知转移瘤寻找原发病灶，19例 WB-DWI 确定原发灶，经病理或其它多项影像学资料证实18例，假阳性1例。4例 WB-DWI 未发现原发灶，经临床或其它多项影像学资料证实2例未找到病灶，假阴性2例,敏感性为90%；85例寻找转移灶中除原发灶外，检出病灶223处，其中真阳性、假阳性分别为201处、22处，假阴性16处，敏感性为92.6%。结论 WB-DWI 对全身转移灶及寻找原发灶方面均有较高的敏感性，可以成为筛查恶性肿瘤患者全身转移及寻找原发灶的一种新型手段。
目的：探討磁共振全身瀰散加權成像技術（WB-DWI）對噁性腫瘤全身轉移及尋找原髮竈的臨床應用價值。方法對80例健康誌願者和23例已知轉移瘤尋找原髮病竈以及85例髮現原髮腫瘤探查有否全身轉移竈行全身WB-DWI 檢查。結果80例健康誌願者均未髮現噁性病變。108例腫瘤患者中，23例已知轉移瘤尋找原髮病竈，19例 WB-DWI 確定原髮竈，經病理或其它多項影像學資料證實18例，假暘性1例。4例 WB-DWI 未髮現原髮竈，經臨床或其它多項影像學資料證實2例未找到病竈，假陰性2例,敏感性為90%；85例尋找轉移竈中除原髮竈外，檢齣病竈223處，其中真暘性、假暘性分彆為201處、22處，假陰性16處，敏感性為92.6%。結論 WB-DWI 對全身轉移竈及尋找原髮竈方麵均有較高的敏感性，可以成為篩查噁性腫瘤患者全身轉移及尋找原髮竈的一種新型手段。

Objective To study the technology of whole body diffusion weighted imaging (WB-DWI) on malignant tumor metastasis and to find the primary clinical application value. Methods 80 healthy volunteers and 23 patients with known metastasis for primary lesions were found in 85 cases of primary tumor and exploration is not systemic metastasis for whole body WB-DWI. Results the malignant lesions were not found in 80 healthy volunteers. 108 cases of tumor patients, 23 cases of known metastases for the primary lesion, 19 cases of WB-DWI confirmed by pathology of primary tumor, or a number of other imaging data confirmed 18 cases, 1 false positive cases. 4 cases of WB-DWI not found in primary lesion, clinical or a number of other imaging data confirm 2 cases did not find the lesion, 2 cases of false negative, sensitivity was 90%; 85 cases for metastasis in primary foci, lesions were detected in 223, of which the true positive, false positive were 201, 22, false negative 16, the sensitivity was 92.6%. Conclusion WB-DWI on systemic metastases and primary tumor had a higher sensitivity for the screening of malignant tumor patients, can become systemic metastasis and to search for a new means of primary.
