Pseudobulbar paralysis is a kind of common clinical syndromes of cerebral vascular diseases, which is manifested as dyslalia, dysphagia and choking. By several-year clinical observations, 36 cases were treated with satisfactory therapeutic effects as reported in the following.Clinical Data Of 36 in-patients, there were 24 males and 12 females, aged from 44 to 81 years, averaging 64.92 years. Of 36 cases, 24 were at the acute stage and 12 at the recovery stage. All the cases were diagnosed as cerebral vascular diseases by cranial CT scan and MRI, of which, 4 were cerebral infarction, 26 lacunar cerebral infarction, 5 cerebral hemorrhage and 1 mixed type. Of 36 cases, 15 were the first attack of wind-stroke, 15 the second attack, 5 the third attack and 1 the forth attack. There were 26 patients with hypertension among 36 cases, of which, 8 patients suffered from hypertension within 10 years, 6 for more than 10 years, 9 for more than 20 years and 3 for more than 30 years. All the 36 cases were associated with dysphagia and agreeable to Standard on Diagnosis and Evaluation of Therapeutic Effects of Wind-stroke issued by the State Scientific Committee 85-919-01-01, 1995.

X-刀立体定向放射神经外科技术治疗松果体区肿瘤
Within three years ,86 cases of tumors in the pineal region were treated by X- Knife radiosurgical technique,using the standard axial serial CT scan for stereotactic localization,the target were localized by the BRW coordinate system.Radionics RSA- 3 X- Knife treatment planning system were used to make plan,Philips SL- 75- 14 Linac was used to produce X- ray.After treatment, follow- up ranged 6~ 42 months (meanly 24 months),most of the patients showed improvements within 1` 6 months. The results of this report proved that the X- Knife treatment for tumors in the pineal region might be an effective,economical and reliable method.

胰腺损伤的CT诊断
胰腺损伤早期临床诊断比较困难,同时由于往往合并有严重的多发伤,如不早期治疗,往往会出现严重的并发症,甚至死亡.笔者回顾性分析腹部闭合性损伤病人中9例经手术证实合并胰腺损伤的病人的CT表现特点,旨在提高对本病的认识.

CT增强扫描中对比剂肾病风险管理
对比剂肾病(contrastinduced nephropathy,CIN)是碘对比剂血管内用药常见并发症,是医源性急性肾功能衰竭的重要原因之一.研究表明:经动脉注药冠状动脉X线造影术CIN的发生率为4%~20%[1-3],在CIN高危因素病人中甚至可能达到40%~90%[4].因此,CIN在血管疾病介入诊疗中是常见不良事件,受到广泛关注.近年来,随着CT技术的发展,对比剂增强CT(contrastenhanced CT,CECT)的检查数迅速增加,尽管CECT检查对比剂给药途径、用药量、病人群体等与X线血管造影不同,CIN的发生率可能相对较小,但由于CECT检查多为门诊患者,院外CIN监测受到限制,且接受CECT检查的绝对人数较多,因此,CECT检查的CIN风险管理也应引起特别重视.本文综述有关文献,对CIN的定义、风险因素,CIN在CECT检查中发生率,以及如何预防做一介绍.

鼻部外伤薄层CT
鼻部外伤临床常见,对单纯鼻骨骨折,X线平片一般不难作出诊断,但对于鼻周相邻部位的骨折及并发改变,由于平片影像相互重叠而不能清楚地显示,造成病变遗漏,延误治疗.因此,我们采用薄层CT检查技术,对48名患者进行检查.现将临床与CT资料分析总结如下.

介绍一种食管CT扫描口服造影剂方法
食管CT扫描一般显示欠佳,如何使其管腔充盈,病灶显示清楚是病变诊断的关键。本文介绍一种口服造影剂的方法,经实践证明效果颇佳。 方法:杏仁霜粉50 g,把60%泛影葡胺稀释为1%~1.5%,用150 ml均匀调和,加热使其粘度增大成透明稠状物,上床后口服约100 ml,躺下即行扫描。 优点:(1)因有粘度,可附在管壁并充盈管腔而显示病变的部位、范围及程度等;(2)无伪影产生;(3)患者无不适感觉;(4)使用方便,价格低廉。

有关高压注射器在CT增强扫描中使用的体会
随着医疗水平的提高,高压注射器在CT增强扫描中的应用也日趋普及,但如何更好、更有效地使用它并有利于提高我们的诊断水平,仍值得深入探讨.我院自1993-05至今,利用高压注射器做了大量增强病例,约有5000多例并就此体会说明如下:

B超、CT在原发性肝细胞癌与胆管细胞癌鉴别诊断中的意义
原发性肝癌中胆管细胞癌(CGC)远较肝细胞癌(PHC)少见,但近年来有增多趋势[1],二者的明确诊断对患者的治疗方案的选择有重要的临床意义.本文回顾性分析了46例PHC和25例CGC的B超、CT检查结果,并对两种影像进行对比研究,着重讨论PHC和CGC两组病例的B超、CT鉴别诊断要点.为临床治疗、术前估计胆管细胞癌(Ρ<0.01);而胆管细胞癌则在合并淋巴结转移及结石上显著高于肝细胞癌(Ρ<0.01),这是两者在临床上的特征性表现.

Objective: To assess the relationship between the prognosis of the patients with diffuse traumatic brain swelling (DTBS) and the changes of the ventricles and the cisterns in CT scans.Methods: The outcome of the patients with DTBS and the changes of the ventricles and the cisterns in CT scans were studied and analyzed in a group of 268 cases.We focused on the changes of the third ventricle and the basal cistern, age and Glasgow Coma Scale (GCS).Results: Of 268 cases, there were changes of the third ventricle and/or the basal cistern in 124, 65 died. In 18 cases, the third ventricle and the basal cistern were both absent and 16 died (88.9%). The third ventricle changed significantly in 59 cases, 33 died (55.9%), while the basal cistern changed in 47 cases and 16 died (34%). Of the 124 patients with changes of the third ventricle and/or the basal cistern, 26 were children, 8 died; 98 adults, 57 died.Conclusions: For patients with DTBS, the outcome was in direct correlation with the change of the third ventricle and/or the basal cistern, the change of the third ventricle was much more important in assessment of the outcome than that of basal cisterns. There is no significant difference in, the incidence of DTBS between children and adults while the outcome of children is much better than that of adults. The patients with the changes of the third ventricle and the basal cistern accompanied with lower GCS scores have poor outcome.
