1、血管造影用多少造影劑?
常血管與其鄰近的軟組織,在X線平片中兩者不能相互區別,因此必須引入改變對X線吸收率的物質(即造影劑)。理想的造影劑應發具有高密度、低毒性、低粘稠度以及易與血液混合和易於排泄等特點。目前常用於周圍動、靜脈造影的均勻水溶性含碘造影劑。

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、醫學影像的PA和AP是什麼意思
醫學影像的PA和AP表示的是後前位和前後位。
在醫學影像中,例如在拍胸片時:
AP是anterior posterio的縮寫,指的是胸片的前後位。lateral 胸片側位,而pa則是面朝板背對球管;ap是背靠板面向球管。多數的胸片為後前位像,也就是說病人面對暗盒,X線束由病人背部射入,經胸腔由前胸壁射出然後到達膠片。前後位胸片為病人面對暗盒的反方向。
註:醫學影像是為了醫療或醫學研究,對人體或人體某部分,以非侵入方式取得內部組織影像的技術與處理過程。它包含以下兩個相對獨立的研究方向:醫學成像系統(medical imaging system)和醫學圖像處理(medical image processing)。
(3)血管造影三維軟組織成像GE擴展資料:
醫學影像技術的應用:
作為一門科學,醫學影像屬於生物影像,並包含影像診斷學、放射學、內視鏡、醫療用熱影像技術、醫學攝影和顯微鏡。另外,包括腦波圖和腦磁造影等技術,雖然重點在於測量和記錄,沒有影像呈顯,但因所產生的數據俱有定位特性,可被看作是另外一種形式的醫學影像。
在臨床應用方面,醫學影像應用於醫學成像,有些醫院會設有影像醫學中心、影像醫學部或影像醫學科,並配備相關的儀器設備,編制有專門的護理師、放射技師以及醫師,來負責儀器設備的操作、影像的解釋與診斷,這與放射科負責放射治療有所不同。
在醫學、醫學工程、醫學物理與生醫資訊學方面,醫學影像通常是指研究影像構成、擷取與儲存的技術、以及儀器設備的研究開發的科學。而研究如何判讀、解釋與診斷醫學影像的是屬於放射醫學科,或其他醫學領域的輔助科學。
4、心血管造影儀在中國的市場大嗎?這方面的設備那一家公司的最牛?GE的心血管造影儀在中國市場佔有率高嗎?
不大 一般正規醫院都有專門配備的 不適合投資
5、血管造影的具體操作
為了使檢查在最佳的衛生條件下完成,您必須位於檢查床旁,在檢查床上鋪上消毒單。 在整個檢查過程中,必須有護士和醫生在場。 腹股溝局部麻醉後將細針插入動脈中。 通過細針將導絲插入血管中。 導絲的作用是曝光下引導合成導管到達需要的位置。通過使用導管注射含碘的造影劑,可以顯示不同器官的血管。 取出導管後,使用綳帶、敷料包紮壓迫穿刺部位進行止血。
血管造影通常指數字減影血管造影(digital substraction angiography, DSA)是指利用計算機處理數字化的影像信息,以消除骨骼和軟組織影像,使血管清晰顯示的技術。Nuldelman於1977年獲得了第一張DSA圖像,已經廣泛應用於臨床,取代了老一代的非減影的血管造影方法。近年來,平板DSA的發展越來越快,在圖像質量和醫患安全性上也不斷進行改善,出現了以西門子Artis zee系列數字平板DSA為代表的新一代診斷設備,為臨床心血管診療提供了數字化新技術。
DSA的成像方式分為靜脈注射數字減影血管造影(IVDSA)及動脈注射數字減影血管造影(IADSA)。前者指經靜脈途徑置入導管或套管針注射對比劑行DSA檢查,可分為非選擇性IVDSA即導管置入外周靜脈或上腔靜脈內顯示動脈影像,及選擇性IVDSA即導管頭置於受檢靜脈或心腔內注射對比劑顯影。後者也可分為非選擇性動脈造影及選擇性動脈造影。非選擇性IADSA是指經動脈途徑穿刺插管後,將導管頭端置於靶動脈的主動脈近端注射對比劑作順行顯影;而選擇性IADSA是指將導管頭端進一步深入到靶動脈的主幹或主幹的分支內進行造影。
6、CT三維重建
核磁共振是可以做三維重建的,而且相對於CT的效果要好,因為核磁的精度高一些,掃描間距也可以設置得小一些。對於軟組織來說,核磁和CT都是可以的。至於三維重建的問題,你要找認識的醫生,否則這是非標准測量,一般的醫院醫生未必會同意的。拿到掃描的核磁或者CT圖片,利用MIMICS軟體可以進行三維重建。

7、血管造影是什麼?
血管造影是在血管里注入顯影劑,X光能夠利用在顯影劑中無法穿透的原理幫助觀察血管的病變情況。血管造影在心臟和大腦檢查中應用較多,醫生通過血管造影能夠正確判斷患者病情,從而做出有效的治療計劃,幫助病人盡快恢復健康.
8、什麼是血管造影
血管造影就是往血管內打入液體狀的血管造影劑,然後用血管造影機照射。碘造影劑是血管造影最常用的造影劑,但是對碘造影劑過敏或腎臟功能不好的患者,就無法採用碘造影劑進行血管造影。血管造影是指將造影劑引入靶血管內,使目的血管顯影,從而達到診斷目的。現在的血管造影通常指數字減影血管造影(,DSA)是指利用計算機處理數字化的影像信息,以消除骨骼和軟組織影像,使血管清晰顯示的技術。Nuldelman於1977年獲得了第一張DSA圖像,目前已經廣泛應用於臨床,取代了老一代的非減影的血管造影方法。
