您要查找的是不是：
- gyri circumflexus [医] 环曲回
- The surface of cerebrum is increased by many gyri. 大脑表面由脑回的增多而增大。
- The gyri are flattened from cerebral swelling. 静脉性梗塞区别于动脉性梗塞的主要特点是静脉窦及皮层血管的扩张和血栓形成，通常可伴有脑表静脉周围的蛛网膜下腔出血，有时还可伴有大面积的脑出血或硬膜下出血。
- gyrus circumflexus 环曲回
- The gyri are narrowed and the sulci widened toward to frontal pole. 脑回变窄，脑沟向着前端变宽。
- The crests of the gyri are most susceptible to the traumatic forces. 脑回顶部容易受到创伤外力的打击。
- Mainly the gyri are affected with hemorrhage from contusions and lacerations. 脑回挫裂伤引起出血。
- The cerebral atrophy seen here mainly in the frontal and parietal regions is characterized by narrowed gyri and widened sulci. 图示脑萎缩主要发生在额叶和顶骨区域，表现为典型的脑回变窄和脑沟变宽。
- Moreover, in lissencephaly (smooth brain), an absence of gyri and sulci and occasionally ventriculomegaly may be noted. 此外，在无脑回（平滑脑）中，可以看看见缺乏脑沟和脑回，偶尔可见脑室扩大。
- If so, thick regions (such as the deep layers of gyri) should contain fewer neurons than thin regions of the cortex. 若是如此，较厚的区域（像是脑回底部细胞层）的细胞数会少于较薄的区域。
- This area of firm, whitened gyri that are broader than surrounding normal gyri is typical for tuberous sclerosis. 结节性硬化症，变硬变白的脑回比周围正常的脑回宽是其典型表现。
- The characteristic feature is the presence of "tubers" which are enlarged and firm, whitened gyri. 组织学上的特征表现为出现结节，它是扩大、变硬、变白的脑回。
- A coronal section through the frontal lobes reveals extensive contusions involving the inferior gyri. 额叶冠状面显示累及下方脑回的广泛挫伤。
- Results In all subjects,99 cases of central sulcus were well identified and the thickness of precentral gyri was bigger than that of postcentral gyri. 结果明确判定中央沟位置的99例;中央前回的厚度大于中央后回的99例;额上沟和中央前沟相交的76例;中央前回与中央后回厚度之比左侧大脑半球为1.;65;右侧大脑半球为1
- Activation of fusiform gyri by faces was strongly affected by attentional condition, but the left amygdala response to fearful faces was not. 透过脸孔，梭状回的活化被注意力的情况强烈地影响，但左侧杏仁核对于恐惧脸孔的反应则没有受影响。
- This is cerebral atrophy in a patient with Alzheimer's disease. The gyri are narrowed and the sulci widened toward to frontal pole. 图示一例阿尔茨海默氏病患者萎缩的大脑。脑回变窄，脑沟向着前端变宽。
- Note that both pre- and post- central gyri, where the primary sensori-motor cortices are located, are relatively hyperperfused. 注意中央前回及中央后回区域，也就是主要的感觉运动皮层定位区在图中呈相对高灌注影。
- The surface of the brain with cerebral edema demonstrates widened gyri with a flattened surface. The sulci are narrowed. 脑水肿病人大脑表面显示脑回变宽、表面平坦，脑沟变窄。
- Seen here are remote contusions, mainly of the right inferior frontal lobe. The crests of the gyri are most susceptible to the traumatic forces. 图示旧挫伤主要存在于额叶右下部。脑回顶部容易受到创伤外力的打击。
- No midline shift could be seen.Cortical gyri and sulci were normal in numbers.Periventricular area was normal.No subdural space could be seen. 脑部才算正常没问题，还是说小孩即使进行脑部超音波检查也不能全部脑区皆完全侦测到!
