胃双对比造影贲门区正面像对早期贲门癌的诊断价值

早期贲门癌诊断是胃肠X线检查难点之一,尤其是癌肿尚未侵入食道下端,临床无吞咽困难症状时,胃肠检查极易漏诊。本文通过200例正常人与11例早期贲门癌的对比观察,着重分析胃双对比造影贲门区正面像的正常形态及早癌X线征象。同时介绍显示贲门区正面像的检查方法、注意事项及有关鉴别诊断问题。认为贲门区正面像显示该区结构清晰,容易发现异常X线征象,对早期贲门癌诊断极为有益,尤其当癌肿未侵入食道下端时,显示病变往往优于其它投照体位。

早期贲门癌的胃肠双对比造影X线征象分析

目的探讨早期贲门癌的X线表现，提高对本病的认识。方洼回顾性分析经手术及病理证实的36例早期贲门癌的X线表现。结果36倒患者在钡餐造影检查中，主要表现黏膜异常增粗、紊乱、肥大，钡剂通过贲门缓慢，贲门痉挛，黏膜纠集、中断，局部呈结节样或大小不一的颗粒状阴影等。结论双对比造影时体位变换和流动技术的合理应用及胃泡充气良好是诊断早期贲门癌的关键技术，仰卧左前斜一右侧位的动态观察方法是早期贲门癌不可缺少的流动观察体住。     

胃底贲门区低张双重造影的一些体会

胃底贲门区用常规钡餐方法检查较难。而采用低张气钡双重造影,周定体位摄片,对显示胃底贲门区病变,尤其是早期癌的诊断有一定实用意义,现介绍我们的一些体会于下。检查前准备和操作方法一、检查前准备:1、检查前准备同胃双重造影法,需禁食、禁水十二小时。2、硫酸钡的选用:我们采用上海马陆厂生产的1号     

浅谈贲门癌的钡餐检查技术

本文报告１０８例贲门癌,着重胃双对比造影时,各种检查体位对于贲 吕的诊断价值,由于贲门胃底部位置高,粘 规则,没有时而动等不利因素,所以在钡餐检查中采取多种体位和方法加以克服显得尤为重要。     

贲门癌的X线诊断

著者总结7O例证实的贲门癌并对41例胃底贲门和食管下端的正常X线表现作了研究。认为: 1.贲门癌侵犯食管下端是常见而重要的征象。诊断中应检出胃底贲门区的粘膜,必要时作气钡双重造影。     

贲门区的检查技术与贲门癌的特殊X线表现

发生在胃底贲门区的癌，由于其所处的解剖部位特殊，有着和胃其它部位发生的癌不同的特点，常需采用一些特别的检查方法以发现其特有的X线表现。贲门区局部解剖复杂，粘膜排列不规律，又缺乏蠕动，并高居于肋弓下，单对比手法触诊或者加压技术常难以施行。双对比造影对贲门癌的检查比胃其它部位癌的检查更为必要。     

正常贲门若干问题的X线研究

由于贲门解剖上的某些特殊性,X线与内窥镜对贲门的检查均受一定的限制.虽然近年对贲门的解剖、形态及功能等方面的研究有所加强,但仍不能满足诊断工作上的要求.自1984年8月起我们以140名贲门正常者为研究对象,采用多体位摄片与录像,进行贲门低张与普通双重对比造影的比较,对贲门双重对比造影中应用低张药的实际效果作进一步观察与评价.测量了正常食管——胃角.对一些易误为病变的X线征象进行了分析.     

贲门癌的X线分析

本文根据130例正常人贲门区的双对比造影检查，对正常人贲门区X线形态及其与功能状态的关系和52例贲门癌X线征象进行分析。正常人贲门区X线表现基本概括有（1）长口型；（2）环行口；（3）放射口状；（4）混合型。在同一检查过程中，当贲门的功能状态发生变化时，贲门形态可从一种类型转变为另一种类型。52例贲门癌（1）胃底贲门块影变形；（2）胃底贲门区溃疡；（3）食管下端受累。

The gastric cardia in double-contrast study: its dynamic image

Difficulties in evaluating the gastric cardia are well known and may often be resolved with the double-contrast technique. Special views to show the cardia en face were obtained in 200 double-contrast examinations. Four basic patterns were recognized. Similar appearances could be reproduced by protruding or retracting the lower end of the esophagus during the radiography of intact stomachs obtained at autopsy. Influenced by muscle relaxants, swallowing, or deep breathing, cardia patterns were found to be interchangeable in the same patient and same examination. The disappearance of the protrusion pattern at the cardia in the course of swallowing is an important means of distinguishing normality from a tumor in this area. Any significant deviation from the normal geometry of the cardia as displayed by double contrast indicates an abnormality. Examples of abnormalities are illustrated.     

Study of the lymph flow of the cardia by endoscopic RI-lymphography with SPECT

Endoscopic RI-lymphography was performed in 29 patients, with single photon emission computed tomography (SPECT) also performed in 19 of them. The lymph flow from the cardia was directly evaluated in lymphograms and compared with the RI uptake of each lymph node and the incidence of lymph node metastasis of previously resected carcinoma of the cardia in patients according to the location of the lymph node. Endoscopic RI-lymphography performed in combination with SPECT was considered to be highly useful for imaging lymph flow of the cardiac region. SPECT and RI-lymphography indicated rich lymph flow from the cardia to the periaortic region, and this finding was consistent with the incidence of lymph node metastasis according to the location of the lymph node in patients who had previously undergone resection of cancer of the cardia. Careful examination for metastasis to lymph nodes around the abdominal aorta was considered to be necessary, especially in patients with carcinoma of the cardia.     

二维超声和数字胃肠对照诊断贲门癌的价值

目的:探讨二维超声与数字胃肠检查对贲门癌的诊断价值。方法:将68例经胃镜活检或手术证实的贲门癌患者的超声及胃肠检查结果与病理结果进行对照。结果:超声与胃肠检查对贲门癌的诊断符合率分别为86.8%、92.6%,无明显差异。对早期贲门癌胃肠检查诊断符合率为77.3%,高于超声的诊断符合率59.1%。而在癌肿对周围组织浸润及远处转移方面的诊断,超声具有无法比拟的优势。结论:超声与胃肠检查相结合诊断贲门癌,可以为临床提供较全面的诊断信息,对临床决策及选取手术方案具有重要价值。     

Malcolm Hanson memorial lecture. MR of the heart: anatomy, physiology, and metabolism

During the initial years, the use of MR imaging focused on the display of normal and abnormal cardiac anatomy. ECG-gated spin-echo imaging provides high-quality static images that clearly depict cardiac anatomy and a variety of anatomic abnormalities. However, it is now becoming clear that, with the addition of recent innovations, MR also is capable of evaluating cardiovascular physiology. With the use of fast imaging techniques, we can acquire images with essentially high temporal resolution so that cardiac function can be quantitated. Moreover, the use of proton and 31P MR spectroscopy provides additional information, which should enable the sequential monitoring of both cardiac function and metabolism.     

Late-onset en coup de sabre of the skull

En coup de sabre is a rare subtype of linear scleroderma that characteristically affects the skin, underlying muscle, and bone of the frontoparietal region of the face and scalp. It typically presents in the first two decades of life, and may be associated with focal neurological deficits. We present a case of late-onset en coup de sabre of the frontal bone where the diagnosis was further complicated by a history of breast cancer, prior trauma to the region, and use of topical medication.     

超声心动图对胎儿主动脉弓峡部血流的频谱分析

目的探讨超声心动图对胎儿主动脉弓峡部血流的频谱分析价值。方法选取我院孕妇156例,行超声心动图检查主动脉峡部内径、血流速度、搏动指数、阻力指数及胎儿左心室排血量、右心室排血量、动脉导管流量以及主动峡部流量情况,并分析上述检测参数与孕周的相关性。结果孕周与峡部内径、收缩早起流速、收缩末期流速、舒张早期流速、舒张中期流速、舒张末期流速、PI、RI呈正相关关系。孕周与胎儿左心室排血量、右心室排血量、联合心输出量、主动脉峡部血流、动脉导管流量呈正相关关系。回归方程结果显示:孕周与峡部内径、收缩早起流速、收缩末期流速、舒张早期流速、舒张中期流速、舒张末期流速、PI、RI拟合程度相对较差,与胎儿左心室排血量、右心室排血量、联合心输出量、主动脉峡部血流、动脉导管流量拟合程度较好。结论正常胎儿超声心动图检查主动脉血流频谱各参数与孕周呈现正相关,其能够为诊断胎儿血流异常提供帮助。     

贲门区常规钡餐造影的正常X线表现

目的分析贲门区常规钡餐造影的正常X线表现。材料与方法采用不使用低张药物和发泡剂的常规钡餐造影检查,取半立位左前斜位摄取贲门区正面X线照片。分析120例正常贲门区的形态。结果贲门区正面图像均可在半立位左前斜位照片上得以清晰显示。正常形态可归纳为四型Ⅰ隆起型,Ⅱ星芒型,Ⅲ环绕型,Ⅳ花朵型。结论正常贲门区域常规钡餐造影具有规律性表现,熟悉其正常形态有助于识别该区域的病变。     

The distribution of gastric ulcers: Double contrast barium meal and endoscopy findings

One thousand consecutive double contrast barium meals and 424 consecutive upper gastrointestinal endoscopic examinations have been reviewed. 70 gastric ulcers were found radiologically in 56 patients and 82 gastric ulcers endoscopically in 70 patients. 55% of radiological and 53.6% of endoscopic ulcers were located in the mid or upper body of the stomach. The distribution is contrary to previous radiological findings with the traditional barium meal. Age did not seem to be a major factor. The double contrast meal and in particular the left anterior oblique view with the head elevated, display en face the lesser curve of the upper body around the cardia where many benign ulcers and carcinomas arise.
