          T1型造影劑介紹及產(chǎn)品列表(包括MRI產(chǎn)品列表)

          核磁共振成像MRI造影劑可以分為縱向弛豫造影劑 (T1制劑)和橫向弛豫造影劑(T2制劑)。T1制劑是通過水分子中的氫核和順磁性金屬離子直接作用來縮短T1,從而增信號,圖像較亮;T2制劑是通過對外部局部磁性的不均勻性進行干擾,使鄰近氫質(zhì)子在弛豫中很快產(chǎn)生相(diphase)來縮短T2,從而減弱信號,圖像較暗。

          弛豫效率是MRI造影劑關(guān)鍵指標(biāo)之一。弛豫效率的樣品,可以使用少的量效果;在造影劑研究領(lǐng)域,紐邁開發(fā)了小型的核磁共振成像分析儀,可測試的測試造影劑T1、T2弛豫時間,并可對試管樣品進行成像,提供定量和定性評價數(shù)據(jù),為造影劑產(chǎn)品的與改進提供的檢測手段。

          目前市面上的T1造影劑產(chǎn)品是Gd釓及Gd的衍生物產(chǎn)品,的就是Gd-DTPA釓噴替酸葡

           

          Magnetic resonance imaging (MRI) is an imaging technique usedprimarily in medical research to produce high quality images of in vivosystems. To track materials within in vivo systems, compounds-of-interest aretagged with materials that possess magnetic properties. These materials, aswell as MRI contrast agents, generally fall into two classes. The first issoluble gadolinium compounds that act through the T1 relaxation process and arebrightening agents. The second is particulate iron oxides that act through theT2 relaxation process and are darkening agents. Each type of contrast agent hasits benefits.
