The study shows that genes in black and white women differ at the molecular level which could be responsible for the aggressive clinical features of breast tumors seen in black women Dr.

研究表明，黑人和 白人女性在分子水平上的基因的差异，导致了黑人妇女在乳癌 肿瘤临床特性的差异。

Objective To discuss the value of DTI on showing white matters surrounding the tumors and in differentiating intracranial tumors also to reconstruct bilateral CSTs using DTT to evaluate its clinical benefit .

目的初步探讨MR扩散张量成像（DTI）在显示颅内 肿瘤与周围 白质关系的价值及其在鉴别诊断中的作用，通过扩散张量纤维束成像（DTT）重建双侧皮质脊髓束，评价其临床应用价值。

Yet while half of the throat cancer patients had HPV-positive tumors 98 percent of the positive tumors were from white patients while a vast majority of black patients had HPV-negative tumors .

然而，有一半的喉癌患者是HPV阳性的肿瘤，阳性肿瘤中98%是 白种人，而绝大多数黑种人患者则是HPV阴性 肿瘤。

Conclusion Visualization of the exact location of vital white matter tracts with respect to cerebral tumors can be shown before operation by DTT .

结论DTT可在术前显示重要的脑 白质纤维束与脑 肿瘤的位置关系，有助于脑 肿瘤 患者术前计划的制定和手术效果的评价。

Objective To evaluate the quantitative relationship between white matter tract ( WMT ) variation resulting from cerebral tumors and shifting of the fractional anisotropy ( FA ) index in magnetic resonance ( MR ) diffusion tensor imaging ( DTI ) .

目的利用MR-DTI技术行三维脑 白质成像，评价脑 肿瘤 对白质束的改变，探讨脑 肿瘤对白质的改变与 瘤周部分各向异性值（FA值）改变的量化对应关系。
