Zhongshan Daxue xuebao. Yixue kexue ban, 2015 【目的】 探讨超声造影（ＣＥＵＳ）在困难部位恶性肿瘤放射性粒子植入治疗中的应用价值。【方法】 超声造影引导下对２４例共３１个困难部位（肿瘤边缘与胆囊、肝门部、胃肠、左右门静脉主干或三支肝静脉、下腔静脉距离不足０．５ｃｍ）的恶性肿瘤行放射性碘粒子植入治疗术。分别于术前和术后１、３、６、１２月进行增强ＣＴ及超声造影随访。根据ＲＥＣＩＳＴ判定标准评价局部疗效，根据超声造影早期增强程度评估病灶血供变化。【结果】平均随访时间１１个月，范围１～４６个月。增强ＣＴ显示术后１、３、６、１２月总有效率分别为０％、７．７％、

The diagnostic value of elastography and ultrasound contrast in papillary thyroid microcarcinoma [PDF]
目的 评估弹性成像与超声造影（CEUS）两种检查技术对鉴别诊断甲状腺微小乳头状癌（TMC）的价值。方法 对常规超声检测出且定性困难的73例80个甲状腺微小结节进行弹性成像及CEUS检查，所有结节均经手术病理证实。比较两种检查方法的准确性。结果 80个结节中CEUS诊断正确率为85.0%（68/80）,其中6例TMC误诊为良性病变，6例良性结节误诊为TMC；弹性成像5分法诊断正确率为92.5%（74/80）,其中3例TMC误诊为良性结节，3例良性结节误诊为TMC。性成像诊断甲状腺微小癌的敏感性94.0%，
