摘要
目的初步探讨磁共振全身弥散技术临床应用价值。方法搜集我院行磁共振全身弥散扫描患者10例,设置10个原发灶观察区及110个转移灶观察区。采用最大密度投影法重建及反窗,获得三维的磁共振全身弥散图像。阳性区域与常规CT和/或MRI的检查进行比较,并做统计学分析。结果磁共振全身弥散技术对肿瘤原发病灶、淋巴结转移灶及骨转移灶的诊断效果与常规CT和/或MRI一致性良好;而磁共振全身弥散技术对实质性脏器转移灶的诊断效果较常规CT和/或MRI稍低,但差异无极显著性统计学意义(P>0.01)。结论磁共振全身弥散技术对全身各系统的恶性肿瘤原发灶及淋巴结与骨转移灶具有很高的诊断价值。
Objective To study the diagnostic value of magnetic resonance whole body diffusion weighted imaging（WBDWI）. Methods Ten patients with malignant tumor underwent WBDWl. Ten primarily regions and 110 metastasis regions were set. Positive focuses were studied and compared with conventional CT and/or MRI. Statistics analysis was done between two groups. Results 10 primarily regions and 110 metastasis regions included Primarily focus, lymph node and ossature metastasis were show by WBDWI as good as conventional CT and/or MRI. Organs metastasis were show by conventional CT and/or MRI better than WBDWI, but had no significance statistics difference （P〉0.01）. Conclusion Primarily focus, lymph node and ossature metastasis could be well diagnosed by WBDWI.
