To evaluate normal development and anomalies of corpus callosum in childhood, magnetic resonance images of 149 children and 20 adults with normal findings were collected to measure the thickness of genu, body and splenium and the length of corpus callosum on the midsagittal T1-weighted images.

我们选择脑部磁振造影所见正常之149位病童及20位成人，由T1为主的(T1-weighted)正中矢状面影像，测定胼胝体在膝部、体部及压部之厚度，胼胝体长度，以及脑前后径。

Non-DAI group also showed decreased NAA/Cr at splenium and increased Cho/Cr at genu of corpus callosum compared with control group (P 0.01), but the change degree was less than DAI group.

与对照组相比，非弥漫性轴索损伤组出现胼胝体膝部胆碱复合物/肌酸和磷酸肌酸升高和压部N-乙酰天冬氨酸/肌酸和磷酸肌酸降低(P 0.01)，但变化程度比弥漫性轴索损伤组低。

The margin of the white matter tract become more clearly with the increasing of the number of gradient encoding directions, especially the detail of the brain stem. But the measured FA of the centrum semiovale, genu and splenium of corpous callosum, the internal capsule, thalamus and the pons with 6, 13 and 21 diffusion gradient encoding directions showed no statically difference.

随着弥散梯度编码方向的增加，FA图质量提高，对白质纤维束细节的显示也更清楚，尤其是对脑干结构的分辨，但成像时间延长；3种不同弥散梯度编码方向的DTI扫描方案所观察到的半卵圆中心、胼胝体膝部、胼胝体压部、内囊、丘脑及桥脑的FA值不存在统计学显著性差异。

The ADC and SNR of centrum semiovale,cingulate gyrus,thalamus, genu and splenium of corpus callosum were calculated separately,and were compared on both conventional DWI and FLAIR-DWI.

结果：扣带回和胼胝体压部的ADC值在施加FLAIR脉冲后显著下降，而半卵圆区、丘脑及胼胝体膝部在施加FLAIR脉冲前后无明显变化；5个部位的DWI图像信噪比在施加FLAIR脉冲后均显著下降（P〈0.01）。

At the first day of life, the sagittal midline cranial sonographic images of CC were obtained through anterior fontanelle under the circumstance of quiescent or sleep stage, the length of CC was measured from the genu to splenium.

156例新生儿，男86例，女70例，包括早产儿96例，平均孕周 32.45±2.71，平均出生体重（1 847.24±512.49）g，於生后当天在静息或睡眠状态下接受经前囟门矢状位颅脑超声探查，胼胝体长度为从膝部至压部。

The average FA of the centrum semiovale, genu and splenium of corpous callosum, the internal capsule, thalamus and the pons in the left and right side were measured of FA map by hand draw region of interest.

在FA图上分别测量两侧半卵圆中心、胼胝体膝部、胼胝体压部、两侧内囊、丘脑及桥脑FA值，并进行统计学分析。

It was found by MRI that the infarcts of5cases were in the genu,27cases in the body and7cases in the splenium,and15patients had more than one infarct and location.The infarct size was2mm×3mm to8mm×17mm.

病例报告］ 39例胼胝体梗死患者中有高血压病史者为35例，糖尿病者为9例，其中合并高血压病史为5例；梗死发生于胼胝体膝部者为5例，干部者为27例，压部者为7例，梗死病灶2个及以上者为15例；病灶大小为2mm×3mm～8mm×17mm。

Results: ADC in MS group was increased in all regions of NAWM compared to controls(P＜0.05),significantly higher in the body of corpus callosum, internal capsule, periventricular WM, frontal WM, parietal WM and occipital WM(P＜0.01). FA value in MS group was decreased in the body of corpus callosum, internal capsule, periventricular WM, frontal WM, parietal WM and occipital WM(P＜0.05), the genu and splenium of CC,middle cerebellar peduncle showed an insignificant trend of lower FA.

结果：MS组的正常表现脑白质的ADC值均高于对照组(P＜0.05)，以胼胝体体部、内囊、侧脑室旁及额、顶、枕叶脑白质更为显著(P＜0.01)；MS组的FA值与对照组比较，胼胝体体部、顶、额、枕叶白质及内囊、侧脑室旁发现明显降低(P＜0.05)，以后4个部位更为显著(P＜0.01)，而胼胝体膝部、压部和小脑结合臂有降低趋势，但无统计学意义。

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。
