Objective To analyze the 16 slice CT features of ovarian teratomas.Methods The CT findings of 35 cases pathologically proved ovarian teratomas were retrospectively analyzed.

回顾性分析经手术及病理证实的卵巢畸胎瘤35例，均行16层螺旋CT检查，并进行横断、冠状、矢状及多平面重建图像。

Teratomas are more or less normal bodily structures—eyes or teeth, for example—that are growing in the wrong place.

像眼睛、牙齿这样的正常身体结构上或多或少的存在畸胎瘤。

Compared with the nine cases of benign teratomas, the four malignant GCTs showed overwhelming male dominance, advanced symptoms at presentation, and poor outcome.

和其他九位成熟畸胎瘤病人比较，恶性生殖芽细胞肿瘤的病人有显著的男性病患倾向，明显的症状及较差的预后。

Fatty, cystic mass and cystic teratomas showed particularly characteristic signs on MRI.

尤其是含脂肪性的肿块，含液囊肿和囊性畸胎瘤具有一定特征性。

If these tumors are mostly solid, then they are often "immature" teratomas with less differentiated tissue and are more aggressive.

如果此肿物中大多数为实性物质，那么经常称为&不成熟性畸胎瘤&，其内含有未分化组织成分且更具侵袭性。

They formed several kinds of tissue in the culture dish and produced tumors called teratomas when they were injected under the skin of immune-compromised mice--both classic characteristics of ES cells.

它们在培养皿中形成了几种肌体组织并且当他们被注射到免疫能力较差的老鼠皮下组织的时候，就会产生一种畸胎瘤。这也是胚胎干细胞的典型特征。

There were all kinds of tissue cells in the teratomas acquired from in-vitro differentiation, such as, neuro epithelium, skeletal muscle, respiratory epithelium. This further proved the isolated mouse ES cells could differentiate into three germ layers of tissue types.

体内分化实验所获得的畸胎瘤中存在各种组织细胞，如一些神经上皮样组织；横纹肌；呼吸上皮样组织等，这进一步证明所分离获得的小鼠ES细胞具有三个胚层的分化能力。

After prolonged culture, the cells formed teratomas when injected into seere combined immunodeficient beige mice and expressed markers characteristic of undifferentiated human ES cells.

经过长时间的培养，在注射到合并严重免疫缺陷的beige小鼠体内后，这些细胞仍可形成畸胎瘤并表达未分化的人ES细胞的特征性标记物。

TVS combining with CDE appears more predictive value in hemorrhagic corpora luteum and mature cystic teratomas.

TVS结合CDE对卵巢良性畸胎瘤及黄体血肿有较高的诊断价值。

Background and objectiveIt has been known that a tooth can be moved gradually from one spot in the oral cavity toa more desirable one by the application of mechanical forces to the tooths crown.

背景和目的在正畸治疗过程中，机械力作用于牙齿，引起牙周组织改建，最终使牙齿发生移动而达到矫治目的。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
