脑回的

The surface of cerebrum is increased by many gyri.

大脑表面由脑回的增多而增大。

Results (1) 6 cases of Tuberous Sclerosis. Diffused subependymal nodular calcification lesions were found in all cases on unenhenced CT. 4 patients are 2 pairs of mother/child relationship. Both of the two mothers are found to suffer from renal angiomyolipoma.(2)1 case of neurofibromatosis showed abnormal spinal canal: scoliosis of thoracic and lumbar spine, concave change of vertebral posterior border. Bilateral renal hypogenesis was found in this patient. Diffused hyper-density lesions were found in kidney and fatty accumulation was found in back skin.(3)6 cases of Sturge-Weber syndrome. On unenhenced CT, curving and strip-shaped calcifications were found along the parietal and occipital gyrus.

结果 ①结节性硬化6例，所有病例CT平扫见两侧脑室室管膜下多发小结节状高密度钙化灶，其中4例为两对母子关系，并见两位母亲合并有肾脏错构瘤，；②神经纤维瘤病1例，MRI表现为椎管异常，胸腰段脊柱侧弯，椎体后缘呈明显的切凹改变；伴有双肾发育不良，CT示肾内多个高密度影，背部皮肤多量脂肪堆积，③脑颜面血管瘤综合征6例， CT可见顶枕部沿脑回分布的弯曲的条状高密度钙化，部分延伸致侧脑室内，增强后见病灶内有扭曲的条状和结节状明显强化的血管影；④小脑血管瘤病4例，影像学表现为小脑内大囊、小结节样占位性病变。

The CT and MRI manifestations of pachygyria and agyria are presented with a review of the pathological features of the disorders and an evaluation of the diagnostic value of both imaging modalities.

结合巨脑回和无脑回畸形的病理特点，研究两种病变的 CT、MRI表现特征，以评价两种影像学检查方法该病变的诊断价值。

The analyses confirm 7 cases with agyria, 5 with pachygyria of bilateral cerebral hemisphere and 3 with limited pachygyria of unilateral hemisphere.

结果显示：CT、MRI显示无脑回畸形 7例，双侧全大脑半球的巨脑回畸形 5例，单侧大脑半球的局限性巨脑回畸形 3例。

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。

Objective: In order to provide reliable morphological basis and new way for imaging study of brain function and the early diagnosis and treatment of small focal disease, a new method of gyri localization on CT films was discussed using the clock localization method.

目的：为了给脑功能影像学研究和脑小病灶的早期定位诊断与治疗提供脑回定位的形态学基础和新方法，探讨横断层CT扫描图像上脑回表盘法定位的可行性。

Precentral gyri thickness more big postcentral gyri in 93 cases.The mean ratio of percentral/postcentral gyri was 1.736 for left hemisphere and 1.652 for right hemisphere.The superior frontal sulci with precentral sulci intersect in 80 cases.At 31 with brain lesion's patients,MR findings with clinical symptom had same location in the brain gyri.

结果 明确判定中央沟位置98例，中央前回的厚度大于中央后回的93例，中央前回与中央后回厚度之比左侧半球：1.736，右侧半球：1.652；额上沟与中央前沟相交的80例，31例患有脑内疾病的磁共振影像病变的位置与临床神经定位是相一致的。

Pachygyria has a distinctive appearance on CT and MRI, including marked thickening of the cortex, broad and flat gyri with shallow sulci, vertically-oriented and shallow Sylvian fissures, and a "figure-of-eight" appearance on axial imaging.

巨脑回畸形在MR和CT上有特征性的表现，包括明显增厚的脑皮质、宽基底扁平的脑回，垂直走行并变浅的大脑外侧裂、轴位像大脑呈8字形改变。

Results: Various extent of gyrus-like or banded calcifications were showed in cortex of 8 all cases, cerebral hemisphere atrophy in 4 cases and thickened skull in 3 cases on the diseased side were accompanied. Ocular hemangioma of choroid and choroids plexus enlargement of lateral ventricle were found in one case. The clinical symptoms and signs of correspondence were found.

结果：8例脑颜面血管瘤综合征均有脑皮层不同程度的脑回样或条带状钙化，4例伴病侧大脑萎缩，3例伴病侧颅板增厚，1例合并眼部脉络膜血管瘤和侧脑室脉络丛增大。8例均出现与CT表现相对应的临床症状和体征。

Lissencephaly is a term used to described a brain with absent or poor sulci formation.

无脑回这个术语用于描述无或只有很少脑沟形成的脑。

Plunder melds and run with this jewel!

掠夺melds和运行与此宝石！

My dream is to be a crazy growing tree and extend at the edge between the city and the forest.

此刻，也许正是在通往天国的路上，我体验着这白色的晕旋。
