1、血管造影用多少造影剂?
常血管与其邻近的软组织,在X线平片中两者不能相互区别,因此必须引入改变对X线吸收率的物质(即造影剂)。理想的造影剂应发具有高密度、低毒性、低粘稠度以及易与血液混合和易于排泄等特点。目前常用于周围动、静脉造影的均匀水溶性含碘造影剂。

Feng Kai: SK-II by the arrogance and strength of the mind
ghd italia, SK-Ⅱ Mask, SK-Ⅱ key whitening liquid foundation Suji OD-3, SK-Ⅱ Run Mining Capture powder Cream OB-2 family were detected in imported procts banned substances chromium and its content is 0.77mg/kg to 2.0 mg / kg.
management article published in vPro line | / darticle3/list.asp? id = 63118 | 1
9 月 14 on the matter the day P & G's statement said procts in the proction process did not add the components involved in the text. Why did not respect the national quality inspection department, said the test results?
9 月 22 日 delisting of P & G said in a statement , but still make the decision until the confirmation that we found in the sale of cosmetics in China contained trace the relevant provisions of chromium and neodymium. Why not declare a Here, we want to say is: Goodbye, SK-II. Bo also called Hing Yan, Xing Yan and Dying. The P & G SK-II heavy storm excessive arrogance, exposing the public relations aspects of the crisis on the local ignorance, and for the services of a famous P & G's international public relations firm is even more agitated, and performance in a crisis too hectic and incompetence.
In fact, P & G should take the initiative to recall the procts, and not return. Had experts believe that the law does not identify the proct in question is indeed the case, return is to protect their own interests. Because the The result is more intensified development of the situation can be described as wasted.
In China, the crisis, first solve the Do not mistake this order! You do not admit, consumers will not forgive you! Unfortunately, more than 400 multinational companies in addition to the marketing staff that embodies the generous paid leave, other humane measures inadequate.
talked about the idea of ??public relations point of crisis, let's look at corporate credit crisis crisis, which is foreign and domestic enterprises should be of concern. This is a very serious and very real problem, because maybe the development of technology, which instry Which companies might have to face and through the examination and tribulations of this lesson!
1. First, the credit crisis from the perspective of foreign brands, he has a deep level of reality and history of the soil.
of the Chinese nation by the bullying powers and the oppressed countries, foreigners and proct potential of distrust and suspicion that has existed in varying degrees. On foreign garbage and foreign environmental protection enterprises will migrate when the newspapers reported that China's side, there are instructions in English and Chinese well-known enterprises does not match the systems on the vehicle recall and two standards with foreign countries and so undoubtedly compromised the image of foreign companies, but also buried the no-confidence the fuse! So the sudden outbreak of anything is the accumulation of quantitative to qualitative change results. So the sense of threat and distrust is the mind of consumers has not been screened, once the outbreak is so foreign brands will be a blow to the credibility and major losses, and his restoration may take many years, not a period of prime-time ad can make up. These procts are not stained with the political atmosphere, for last year's Colgate crisis for Mitsubishi, we really can not imagine.
3、医学影像的PA和AP是什么意思
医学影像的PA和AP表示的是后前位和前后位。
在医学影像中,例如在拍胸片时:
AP是anterior posterio的缩写,指的是胸片的前后位。lateral 胸片侧位,而pa则是面朝板背对球管;ap是背靠板面向球管。多数的胸片为后前位像,也就是说病人面对暗盒,X线束由病人背部射入,经胸腔由前胸壁射出然后到达胶片。前后位胸片为病人面对暗盒的反方向。
注:医学影像是为了医疗或医学研究,对人体或人体某部分,以非侵入方式取得内部组织影像的技术与处理过程。它包含以下两个相对独立的研究方向:医学成像系统(medical imaging system)和医学图像处理(medical image processing)。

医学影像技术的应用:
作为一门科学,医学影像属于生物影像,并包含影像诊断学、放射学、内视镜、医疗用热影像技术、医学摄影和显微镜。另外,包括脑波图和脑磁造影等技术,虽然重点在于测量和记录,没有影像呈显,但因所产生的数据俱有定位特性,可被看作是另外一种形式的医学影像。
在临床应用方面,医学影像应用于医学成像,有些医院会设有影像医学中心、影像医学部或影像医学科,并配备相关的仪器设备,编制有专门的护理师、放射技师以及医师,来负责仪器设备的操作、影像的解释与诊断,这与放射科负责放射治疗有所不同。
在医学、医学工程、医学物理与生医资讯学方面,医学影像通常是指研究影像构成、撷取与储存的技术、以及仪器设备的研究开发的科学。而研究如何判读、解释与诊断医学影像的是属于放射医学科,或其他医学领域的辅助科学。
4、心血管造影仪在中国的市场大吗?这方面的设备那一家公司的最牛?GE的心血管造影仪在中国市场占有率高吗?
不大 一般正规医院都有专门配备的 不适合投资
5、血管造影的具体操作
为了使检查在最佳的卫生条件下完成,您必须位于检查床旁,在检查床上铺上消毒单。 在整个检查过程中,必须有护士和医生在场。 腹股沟局部麻醉后将细针插入动脉中。 通过细针将导丝插入血管中。 导丝的作用是曝光下引导合成导管到达需要的位置。通过使用导管注射含碘的造影剂,可以显示不同器官的血管。 取出导管后,使用绷带、敷料包扎压迫穿刺部位进行止血。
血管造影通常指数字减影血管造影(digital substraction angiography, DSA)是指利用计算机处理数字化的影像信息,以消除骨骼和软组织影像,使血管清晰显示的技术。Nuldelman于1977年获得了第一张DSA图像,已经广泛应用于临床,取代了老一代的非减影的血管造影方法。近年来,平板DSA的发展越来越快,在图像质量和医患安全性上也不断进行改善,出现了以西门子Artis zee系列数字平板DSA为代表的新一代诊断设备,为临床心血管诊疗提供了数字化新技术。
DSA的成像方式分为静脉注射数字减影血管造影(IVDSA)及动脉注射数字减影血管造影(IADSA)。前者指经静脉途径置入导管或套管针注射对比剂行DSA检查,可分为非选择性IVDSA即导管置入外周静脉或上腔静脉内显示动脉影像,及选择性IVDSA即导管头置于受检静脉或心腔内注射对比剂显影。后者也可分为非选择性动脉造影及选择性动脉造影。非选择性IADSA是指经动脉途径穿刺插管后,将导管头端置于靶动脉的主动脉近端注射对比剂作顺行显影;而选择性IADSA是指将导管头端进一步深入到靶动脉的主干或主干的分支内进行造影。
6、CT三维重建
核磁共振是可以做三维重建的,而且相对于CT的效果要好,因为核磁的精度高一些,扫描间距也可以设置得小一些。对于软组织来说,核磁和CT都是可以的。至于三维重建的问题,你要找认识的医生,否则这是非标准测量,一般的医院医生未必会同意的。拿到扫描的核磁或者CT图片,利用MIMICS软件可以进行三维重建。

7、血管造影是什么?
血管造影是在血管里注入显影剂,X光能够利用在显影剂中无法穿透的原理帮助观察血管的病变情况。血管造影在心脏和大脑检查中应用较多,医生通过血管造影能够正确判断患者病情,从而做出有效的治疗计划,帮助病人尽快恢复健康.
8、什么是血管造影
血管造影就是往血管内打入液体状的血管造影剂,然后用血管造影机照射。碘造影剂是血管造影最常用的造影剂,但是对碘造影剂过敏或肾脏功能不好的患者,就无法采用碘造影剂进行血管造影。血管造影是指将造影剂引入靶血管内,使目的血管显影,从而达到诊断目的。现在的血管造影通常指数字减影血管造影(,DSA)是指利用计算机处理数字化的影像信息,以消除骨骼和软组织影像,使血管清晰显示的技术。Nuldelman于1977年获得了第一张DSA图像,目前已经广泛应用于临床,取代了老一代的非减影的血管造影方法。
