Methods Twenty-three cases of OSAS patients proved by polysomnography were examined with MRI. The cross-sectional area of retropalatal region, retroglossal region, epiglottal region and the lateral parapharyngeal fat pad of RP region was calculated. The thickness of bilateral and posterior pharyngeal wall and other indices were also measured. 30 nonsnoring age-matched normal subjects were selected as the control group. 15 patients underwent turbo field echo T1-weighted imaging during sleep. The images of RP, RG, and EPG were analyzed. Results In oSAS group, the cross sectional area of RP and RG regions was smaller than that of the control group.

应用MRI对23例经多导睡眠监测（polysomnography， pSG）确诊的OSAS患者及30例无打鼾的健康成人进行上气道检查，于轴面图像测量软腭后区（retropalatal region， RP区）、舌根后区（retroglossal region， RG区）和会厌区（epiglottal region， EPG区）的气道截面积，各区前后、左右径及其比值，各区咽侧壁、咽后壁软组织厚度，RP区咽旁间隙（lateral parapharyngeal fat pad，LPFP）截面积，于正中矢状面图像测量软腭厚度、长度及截面积，对两组各项检查指标进行统计学分析。

Methods In all the 7 cases we employed traditional osteotomies, bone resection and bone graft fixation through coronary and nasofrontal incisions to reduce their interorbital distance.

所有7例患者均采用传统颅内外联合径路手术，通过双侧头皮冠状切口和鼻正中部眉间矢状切口行眶周截骨，眶内移和骨块固定，缩小内眶距。

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。

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。
