            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(guò)水分子中的氫核和順磁性金屬離子直接作用來(lái)縮短T1,從而增信號(hào),圖像較亮;T2制劑是通過(guò)對(duì)外部局部磁性的不均勻性進(jìn)行干擾,使鄰近氫質(zhì)子在弛豫中很快產(chǎn)生相(diphase)來(lái)縮短T2,從而減弱信號(hào),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(kāi)發(fā)了小型的核磁共振成像分析儀,可測(cè)試的測(cè)試造影劑T1T2弛豫時(shí)間,并可對(duì)試管樣品進(jìn)行成像,提供定量和定性評(píng)價(jià)數(shù)據(jù),為造影劑產(chǎn)品的與改進(jìn)提供的檢測(cè)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.

            Gadoluminate is the first commerciallyavailable ultra-small gadolinium oxide colloid for use in a wide range of MRIand MRA applications. This product is a 30 nm gadolinium colloid and itprovides a strong T1 brightening signal that is comparable to the same molarconcentration as Gd-DTPA. However, due to its colloidal size and neutralcharge, this reagent is retained in the vascular space. The measured bloodhalf-life (t½) of Gadoluminate in a swine model is approximately 12.5 hours andapproximately 11.9 minutes in a mouse model.

            Two ml of Gadoluminate is packaged in a 2ml sealed serum bottles. The product is a 30 nm gadolinium colloid atconcentration of 10 mg Gd/ml.
