• OCTA與皮膚傷口愈合——OCTA監(jiān)測(cè)急性創(chuàng)傷及愈合過(guò)程中的結(jié)構(gòu)和脈管系統(tǒng)變化

  在臨床、醫(yī)學(xué)和皮膚病學(xué)研究中，對(duì)皮膚血管和結(jié)構(gòu)特征檢查是必不可少的程序，然而目前還沒(méi)有比較合適的非侵入式成像工具能夠清晰準(zhǔn)確地評(píng)估皮膚的血管和結(jié)構(gòu)特征。華盛頓大學(xué)的Wendy Wang等人使用光學(xué)相干斷層掃描血管造影術(shù)(OCTA)，對(duì)急性創(chuàng)傷及愈合過(guò)程中的組織結(jié)構(gòu)和脈管系統(tǒng)進(jìn)行了深度達(dá)1.2 mm的成像和分析，測(cè)量了不同深度的血管密度和直徑等關(guān)鍵血管參數(shù)。觀察發(fā)現(xiàn)皮膚脈管系統(tǒng)的改變與主動(dòng)愈合有關(guān)，淺血管的第一反應(yīng)是直徑增加，而深血管的第一反應(yīng)是密度增加。此外，與較深的血管相比，淺血管似乎會(huì)更早恢復(fù)正常。該研究成果為表征皮膚的血管結(jié)構(gòu)特征提供了可靠依據(jù)，并以“Optical Coherence Tomography Angiography and Cutaneous Wound Healing”為題發(fā)布于SPIE. Photonics West BIOS, 2018會(huì)議期刊。[詳細(xì)]

• Biomed. Opt. Express：OCTA表征早期皮膚輻射損傷

  皮膚輻射損傷（CRI）是由暴露于高劑量電離輻射（IR）引起的皮膚損傷。由于Z初的臨床潛伏期和隨后的炎癥爆發(fā)，導(dǎo)致CRI的診斷和治療較為困難。因此臨床癥狀出現(xiàn)前早期檢測(cè)CRI將有助于有效治療。韓國(guó)研究人員JUNGBIN LEE等證明光學(xué)相干斷層掃描血管造影術(shù)（OCTA）可以非侵入性地檢測(cè)CRI小鼠模型潛伏期內(nèi)的皮膚變化。通過(guò)暴露于各種紅外劑量在小鼠后肢誘導(dǎo)CRI，通過(guò)OCTA縱向成像損傷的皮膚區(qū)域直到臨床癥狀出現(xiàn)。觀察發(fā)現(xiàn)OCTA檢測(cè)到皮膚的一些變化，包括皮膚增厚、大血管擴(kuò)張和血管邊緣不規(guī)則。組織學(xué)研究也證實(shí)了OCTA的發(fā)現(xiàn)。表明OCTA可用于早期CRI檢測(cè)。研究成果以“Characterization of early-stage cutaneousradiation injury by using optical coherence tomography angiography”為題發(fā)表于Biomedical Optics Express。[詳細(xì)]
