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。     

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     

多层螺旋CT对胫骨平台骨折的诊断价值

目的:评价MSCT在胫骨平台骨折的分类及制定合理的治疗方案方面的价值。方法:对24例常规X线平片或临床诊断为胫骨平台骨折的患者进行MSCT扫描,并对图像进行MPR、SSD和VR重建,对骨折的部位、范围、碎骨片的数量或骨折程度、胫骨平台受累情况、手术入路、骨质疏松程度及骨组织的缺损等做出评价。骨折的分型根据Swiss AO-ASIF法。结果:24例患者中有19例进行了手术治疗,术中所见与轴位MSCT和MPR、SSD及VR重建图像综合做出的诊断一致。结论:MSCT及其MPR、SSD、VR重建技术对于胫骨平台的骨折分型及术前评价有重要意义。     

多层螺旋CT在胰腺癌诊断中的应用

多层螺旋CT（MSCT）使扫描速度，薄层，覆盖范围达到了很好的统一，是胰腺癌最佳的单项检查手段。本文介绍了MSCT运用于胰腺的技术优势以及具体检查方法，重点叙述其在胰腺癌的诊断，术前可切除性的评估等方面的应用。     

碘对比剂在CT检查中的应用

我院自 1994年使用CT检查以来 ,需增强检查者的比例越来越高。增强检查确实提供了CT平扫不可替代的诊断信息 ,但是碘对比剂的副作用却令人担忧 ,因此 ,CT室的护理人员应认真做好对患者的筛选、敏试工作 ,严格掌握禁忌证 ,加强对副反应的预防性措施及意外抢救工作 ,合理使用对比剂 ,现将我院应用碘对比剂的方法介绍如下。1　严格掌握禁忌证严重的甲状腺功能亢进、失代偿性心肌功能不全者禁忌。妊娠及急性盆腔炎症时禁行子宫输卵管造影。2　认真筛选高危因素有碘造影剂过敏、严重肝肾功能损害、心脏和循环功能不全、肺气肿、体质极差者 ,重…     

Interobserver Agreement for the Diagnosis of Venous Thromboembolism on Computed Tomography Chest Angiography and Indirect Venography of the Lower Extremities in Emergency Department Patients

Objectives: To determine interobserver agreement between radiologists for computed tomography (CT) angiography and venography. CT venography of the lower extremities combined with standard CT angiography of the chest may result in an increased overall diagnosis rate of venous thromboembolism (pulmonary embolism or deep venous thrombosis).
Methods: The study had a retrospective cohort design. The population consisted of emergency department patients who were evaluated for suspected pulmonary embolism. A random sample of 50 patients diagnosed and treated for venous thromboembolism and 50 age- and gender-matched patients whose CT angiograms and venograms were read as negative were enrolled. The original reading (R1) was compared with readings of two study radiologists: R2, a general radiologist, and R3, a radiologist with fellowship training in cross-sectional imaging. All readers were blinded to each other.
Results: Both R2 and R3 found both CT angiogram and venogram components technically adequate in 95% (95% CI = 89% to 98%) and 86% (95% CI = 78% to 92%) of studies, respectively. The agreement was very good for CT angiography (lowest agreement = 92%; lowest κ = 0.83) and was good for CT venography (85%, κ = 0.65). In nine cases, R1 read the CT angiogram as negative but the venogram as positive for DVT, whereas both R2 and R3 read both components as negative in four of these nine, suggesting a false-positive isolated DVT rate of 44% (95% CI = 19% to 73%). In no case did R1 read both scan components as negative when R2 and R3 agreed on presence of pulmonary embolism or DVT.
Conclusions: Diagnosis of pulmonary embolism on CT angiography is more reliable than diagnosis of isolated DVT on CT venography.     

胸壁病变的CT与X线诊断

目的:探讨CT、X线诊断胸壁病变的价值。材料和方法:回顾性分析53例胸壁病变的CT和X线表现,并评估其诊断价值。结果:53例中,CT确诊52例,X线平片确诊41例。正常7例,炎性和脓肿3例、骨折6例、胸膜病变12例(粘连4例、胸膜增厚3例、胸膜钙化3例、结核瘤2例)、良性肿瘤9例(脂肪瘤3例、神经纤维瘤3例、嗜酸性肉芽肿2例、间皮瘤1例)、恶性肿瘤16例(转移瘤13例、骨髓瘤3例)。结论:CT正确诊断率(98%)明显高于X线(77%),可以明确诊断胸壁病变,能发现X线平片不能发现的征象,具有较高的诊断价值。
