新型納米磁共振成像(MRI)造影劑/核磁共振納米燈/順磁性MRI造影劑技術(shù)

全新的納米磁共振成像(MRI)造影劑技術(shù)，能夠大幅度提升醫(yī)學(xué)圖像的可識別度。動物實驗結(jié)果表明，使用該造影劑，實驗鼠異常組織的亮度是周圍健康組織亮度的10倍。新的造影劑技術(shù)具有選擇性，形成的核磁共振圖像對**癥等特定代謝的標志物敏感。

納米造影劑基于磁諧振技術(shù)，主要由兩種磁性材料組成，包括“開關(guān)材料”(磁性納米顆粒)和“顯影材料”(順磁性MRI造影劑)，兩種材料之間的距離不同，核磁共振圖像的亮度也不同。兩種材料之間的臨界距離大于7納米時，開關(guān)材料對顯影材料的影響消失，順磁性造影劑在MRI圖像上充分顯影，此時相當于開關(guān)的“開”;當二者距離小于7納米時，順磁性顯影材料在MRI圖像上的狀態(tài)則是“關(guān)”。

研究人員制造了一種足以探測實驗鼠體內(nèi)**癥的造影劑。造影劑使用一種能夠被**癥代謝產(chǎn)物MMP-2酶切斷的生物材料連接“開關(guān)材料”和“顯影材料”，令兩種材料之間的初始距離低于7納米。顯影劑注入實驗鼠組織后，如果組織中存在**變，兩種材料之間的連接將會被MMP-2酶切斷，導(dǎo)致兩種材料分離，MRI圖像會將病灶區(qū)域顯示為高亮度。

使用納米造影劑技術(shù)，MRI檢查能夠顯示**的存在和具體分布，還可以通過圖像揭示**組織中MMP-2酶的濃度，獲得**變分期等進一步信息。
