肩胛骨骨折的螺旋CT多平面和三维重建诊断

目的 探讨螺旋CT多平面重建（MPR）、表面遮盖显示法（SSD）及最大密度投影法（MIP）在肩胛骨骨折诊断中的价值。方法 回顾性分析40例肩胛骨骨折患者的MPR、SSD及MIP图像；所有病例均用Mareoni Ultra Z型螺旋CT机扫描，并在图像工作站上用MPR、SSD及MIP技术获得多平面和三维图像。结果 MPR、SSD及MIP重建图像清晰显示了40例共45处肩胛骨骨折及7例肩关节脱位；MPR、SSD及MIP能多方位、立体、全面地显示肩胛骨骨折部位和程度。MPR在显示微小骨折方面较好，而MIP、SSD在显示骨折的位置、形态、范围及移位方面较好。结论 MPR、SSD及MIP是诊断肩胛骨骨折的有效方法，对肩胛骨骨折分类、手术入路及内固定器选择等方案的制定有帮助。     

颈椎病与中医辨证关系的探讨(附100例分析)

目的:探讨颈椎病与中医分型的辨证关系。方法:对100例该病的影像表现与中医分型进行系统分析。结果:主要临床表现颈部活动受限,颈、肩、背部疼痛,常伴头痛、头晕、视物模糊、耳鸣等症状。风寒型以软组织所致颈曲改变为主。肝肾亏虚型、痰湿交阻型以骨质增生、椎间隙及椎间孔狭窄为主。结论:X线、CT是本病首选检查方法,能与中医辨证有机结合,对中西医治疗有重要意义。

出血性脑梗死58例临床分析

出血性脑梗死（hemorrhagic infarction，HI）指脑梗死后梗死区内血液再灌注引起的继发性出血，由Liedll在1872年首次报道，近年来已受到越来越多的重视。HI既往多为病理检查时发现，目前随着CT和MRI的发展，临床诊断率已大大提高。现将我院1996年7月-2006年7月收治的经CT或MRI证实的58例HI患者资料分析如下。     

Correspondence analysis as a screening method for indicants for clinical diagnosis

In clinical diagnosis, a patient's symptoms are observed and the probabilities of various diseases are assessed. A widely used method of formalizing this approach is independent Bayes in which symptoms are assumed to be independent conditional on the disease category. Correspondence analysis provides a method for examining the dependence between symptoms and assists in the selection of a reduced set of symptoms for the application of the independent Bayes method. This approach is illustrated on two data sets concerned with patients attending Accident and Emergency departments with chest pain and acute abdominal pain, respectively.     

新生儿缺氧缺血性脑病143例颅脑CT分析

目的:评价CT检查对新生儿缺氧缺血性脑病(HIE)的诊断价值。方法:使用CT扫描仪,用OM基准线、0度角、层厚及层距5mm连续平扫至颅顶。结果:189例临床怀疑HIE的新生儿,CT阳性发现HIE143例,合并蛛网膜下腔出血22例,分别占受检者75·66%和11·64%。结论:对可疑HIE患儿行颅脑CT扫描,对临床上早期诊断HIE提供了可靠依据。它不但可以直观地提供病损部位与程度,而且对推测预后具有重要意义。     

The relationship between jaw deformity and scoliosis

Objectives To analyze the relationship between lateral displacement of the mandible and scoliosis. Methods From April 2002 through July 2003, we examined posteroanterior cephalometric radiographs and chest X-rays from 85 patients with jaw deformities and a control group of 20 patients with no jaw deformities. To measure the lateral shift of the mandible, we drew a horizontal baseline (X axis) on the cephalogram connecting the intersection of the external margins of the orbits and the most lateral points of the greater wings of the sphenoid. A vertical baseline (Y axis) was then marked perpendicular to the X axis, intersecting the ethmoid crista galli. Then, we measured the lateral displacement of the mandibular mentum from the Y axis. Displacement to the right was designated positive; that to the left was designated negative. Cobb's method was used to measure scoliosis curves on chest X-rays; the direction of the curve was designated similarly. Results Of the 85 patients with jaw deformity, 23 (27.1%) had a Cobb angle exceeding 10°. None of the control group had scoliosis exceeding 10°. No correlation was found between the direction of mandibular displacement and the direction of scoliosis. Conclusion This study suggests a relationship between jaw deformities and scoliosis, as scoliosis was found in 27.1% of the patients with a main complaint of jaw deformity.     

CT在老年人硬膜下血肿诊断中的作用

老年人硬膜下血肿(SDH)系指60岁以上高龄人的SDH而言。由于近年来各国人口老年化率上升,老年人颅脑损伤的比例也随着增高,老年SDH也相应增多[1]。这类病人的临床表     

外伤性脑梗死的CT诊断

目的总结外伤性脑梗死的CT特征,探讨其发生机制,揭示其对疾病预后的判定价值。方法回顾性分析40例外伤性脑梗死患者头颅CT表现及相关临床资料。结果轻微外伤引起的脑梗死多发于儿童,好发部位为基底节内囊区,预后较好;重症外伤引起的脑梗死好发于成人,发病部位多见于颅内血肿同侧,且大脑后动脉支配区域最为多见,预后较差。结论CT扫描对外伤性脑梗死的诊断及预后判定有重要价值。
