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。

Moreoer, in lissencephaly, an absence of gyri and sulci and occasionally entriculomegaly may be noted.

此外，在无脑回中，可以看看见缺乏脑沟和脑回，偶尔可见脑室扩大。

The surface of the brain with cerebral edema demonstrates widened gyri with a flattened surface.

脑水肿病人大脑表面显示脑回变宽、表面平坦，脑沟变窄。

The gyri have been described as "mushroom" like. It is easily recognized by gross inspection during brain cutting and by MRI.

这种脑回在尸体解剖时可见脑回萎缩，不规则，被称「蕈茹状」。

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。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
