Objective To discuss CT features of Leiomyosarcoma on abdomen and to evaluate CT scanning in its diagnosis.

摘 要］目的：探讨腹部平滑肌肉瘤的CT表现特点及其诊断价值。

Abdominoperineal resection is an appropriate choice of treatment for patients with operable rectal leiomyosarcoma due to its lower local recurrence rate.

因为局部的复发率较低，腹部会阴切除术是一种适合可手术的直肠平滑肌肉瘤病人的手术方法。

The gonads open near the base of the abdomen and the excretory organs are usually Malpighian tubules.

生殖腺开口于近腹部基部，排泄器官通常为马氏管。

The diagnosis of malrotation depends on history, signs, X-ray abdominal film and enema.

先天性肠旋转不良的诊断依据为病史、体征、X线腹部平片和钡剂灌肠。

Craniocaudal view and mediolateral oblique were conducted for each patient.If necessary,mediolateral view or spot view was operated. All cases take plain scanner and contrast-enchanced scanner with use of a helical CT (Somatom AR.SP).For a patient,a field view was chosen that field depict the whole breast,as well as the ipsilateral axillary and internal mammary chains.

SP螺旋CT机进行平扫和增强扫描，扫描范围从腋窝顶部至乳房下界。23例全部采用增强扫描，分别在注射造影剂100ml后30s、60s、90s时进行动脉相、静脉相、延迟相CT扫描，病人采用俯卧位，上胸及腹部垫高，使乳房自然下垂，双臂交叉放在头上。

Seven morphological parameters of hair were observed on the lanugo of a roe deer fetus 10 to 15 days before birth by linear eyepiece micrometer and optical microscope, which include hair density, hair length, medulla length, hair diameter, medulla diameter, scale pattern, and medullar pattern. Results indicate that the development of lanugo expresses temporal and spatial sequence, namely, hair occurs from head to tail.

利用线性目微尺和光学显微镜测量比较了距出生还有10~15d的狍颈部、背部、腹部、臀部、后肢上部的胎毛密度、毛长度、髓质长度、毛细度、髓质细度，并对鳞片和髓质形态进行了观察，发现狍胎毛的发生具有时间和空间上的顺序性，即毛的发生从头颈部向体后扩展。

Main symptoms were vomiting and upper abdomen pain. Midgut volvulus presented distention and tenderness. Intestinal gangrene presented haematemesis and melena.

诊断主要依据出生3～7天后大量胆汁样呕吐，腹部立位平片及上消化道气钡造影、钡剂灌肠，B超、CT、MRI亦有意义。

A mean age was 11.3 months （range from 2d to 13 years old）. 31.87% of them presented symptoms in the infant period. Main symptoms were vomiting and upper abdomen pain. Midgut volvulus presented distention and tenderness. Intestinal gangrene presented haematemesis and melena.

诊断主要依据出生3～7天后量胆汁样呕吐，腹部立位平片及上消化道气钡造影、钡剂灌肠，B超、CT、MRI亦有意义。

Abstract］ Objective To study the diagnostic value and CT findings in mesenteric trauma of traffic accident.

目的 探讨腹部车祸所致肠系膜损伤的CT表现及诊断价值。

A Contrast-enhanced CT scan of the upper abdomen shows a saclike mass of dilated jejunal loops between the pancreatic head and stomach. The descending mesocolon and stomach are displaced laterally. The dilated inferior mesenteric vein is located at the anterior border of the encapsulated loops.

a 上腹部增强CT扫描显示胰头和胃之间见囊状成簇扩张的空肠，降结肠系膜和胃被推移到侧方，扩张的肠系膜下静脉是疝囊内肠襻的前界。

Finally, according to market conditions and market products this article paper analyzes the trends in the development of camera technology, and designs a color night vision camera.

最后根据市场情况和市面上产品的情况分析了摄像机技术的发展趋势，并设计了一款彩色夜视摄像机。

Only person height weeds and the fierce looks stone idles were there.

只有半人深的荒草和龇牙咧嘴的神像。
