GGA is a nonspecific finding. ? When diffuse GGA is observed, radiologists should… I. Pay attention to the additional radiographic findings and clinical features. II. Keep in mind that pulmonary edema is the most common cause of diffuse GGA. III. Also consider the possibility of viral pneumonia when infections are suspected. PCP or CMV pneumonia are the common life-threatening infectious complications in immunocompromised patients. 2019年已經(jīng)過去了一半,您是否還在為啞巴專業(yè)英語苦惱?告別啞巴專業(yè)英語,從朗讀開始?!睹刻炖首x一段醫(yī)學(xué)影像學(xué)英語》,開通一年多,已累積3.5萬篇打卡日記?,F(xiàn)在加入,和自律的人一起天天打卡,做最好的自己!原價每月20元,整個七月還能享受限時優(yōu)惠10元,還有7天免費試用期!現(xiàn)在就趕緊加入吧!如果覺得好,請推薦給周圍的朋友,請他們和您一起精進吧! 精彩PPT(032):中毒性、代謝性、自身免疫性腦病的磁共振成像:放射科醫(yī)生須知 精彩PPT(031):肺微結(jié)節(jié)的HRCT診斷及鑒別診斷思路 精彩PPT(030):具有對稱性DWI異常的非缺血性神經(jīng)綜合征:影像表現(xiàn)及診斷思路 精彩PPT(029):顱內(nèi)DWI高信號病變:從發(fā)現(xiàn)病灶到準確診斷 精彩PPT(027):磁敏感加權(quán)像的臨床應(yīng)用及限度 精彩PPT(026):小兒足踝骨折表現(xiàn)、鑒別診斷、并發(fā)癥及治療 精彩PPT(024):慢性胰腺炎與胰腺癌的影像學(xué)鑒別診斷思路 精彩PPT(023):腹部及盆腔脾種植:非典型表現(xiàn)、診斷陷阱及鑒別診斷 精彩PPT(022):海綿竇影像學(xué):影像-病理對照 精彩PPT(021):進展期前列腺癌下一代影像學(xué)檢查概覽 精彩PPT(018):冠狀動脈疾病報告和數(shù)據(jù)系統(tǒng)(CAD-RADS):挑戰(zhàn)極限 精彩PPT(017):白質(zhì)出了什么問題?根據(jù)獲得性脫髓鞘疾病的MRI特征進行鑒別診斷的病例分析 精彩PPT(016):上葉為主的病變的影像學(xué)鑒別診斷思路 精彩PPT(015):未來的乳腺影像專家:了解臨床醫(yī)生的需求 精彩PPT(014):肝細胞癌診斷中的誤區(qū):防止在2018版LI-RADS應(yīng)用中的人為失誤 精彩PPT(013):肝腺瘤的Bordeaux分型及其影像學(xué)特征 精彩PPT(012):心包疾病的多模態(tài)影像學(xué)評估及病理對照 精彩PPT(011):谷歌翻譯在放射學(xué)術(shù)語的英漢轉(zhuǎn)化中的準確性研究 精彩PPT(010):肺腺癌TNM分期第8版:放射科醫(yī)生須知 精彩PPT(009):當(dāng)心!原發(fā)腫瘤為小細胞肺癌的腦轉(zhuǎn)移 精彩PPT(005):散發(fā)性腦小血管病的觀念演變及對放射科醫(yī)生的啟示 精彩PPT(004):TB or not TB? 骨結(jié)核影像特征 精彩PPT(002):MRI在唇腭裂的產(chǎn)前診斷中的價值評估 彭洋:腎上腺中空征在感染性休克患者中的發(fā)生率、CT表現(xiàn)及預(yù)后研究 王煥軍:盆腔內(nèi)外疾病導(dǎo)致的梗阻性精子缺乏的MRI表現(xiàn) 關(guān)鍵:盆腔內(nèi)外疾病導(dǎo)致的非梗阻性精子缺乏的MRI表現(xiàn) 神經(jīng)系統(tǒng)疾病的胸部表現(xiàn):全面圖文復(fù)習(xí) 放射科醫(yī)生的間質(zhì)性肺病(ILD)多學(xué)科會診(MDC)“生存指南” RSNA期間,中國學(xué)者團訪問美國西北大學(xué)放射科 原發(fā)及繼發(fā)性硬化性膽管炎:基于影像模式的診斷管理指南 RSNA期間,中國學(xué)者團訪問美國西北大學(xué)放射科 柳學(xué)國:CT影像組學(xué)模型預(yù)測早期肺癌生存期 RSNA2018:虛擬放射醫(yī)生:深度學(xué)習(xí)在放射學(xué)的現(xiàn)狀及其未來趨勢 |
