JCO:MRI获胜!90%乳腺癌可通过MRI筛选出来

2015-04-08 Zhang JL译 MedSci原创

大约90%的乳腺癌可以通过磁共振成像(MRI) 明确诊断。相比之下,乳房钼靶检查结合超声检查对乳腺癌的检出率仅为37.5%。这是一个最新发表在Journal of Clinical Oncology杂志上研究的关键发现。该项研究由维也纳医科大学的放射科、核医学科与妇产科和临床病理学研究所联合进行。“在有丝毫怀疑的情况下,尤其是对于风险增加的女性,显然核磁共振是可取的选择。我们的研究清楚地显示了磁共

大约90%的乳腺癌可以通过磁共振成像(MRI) 明确诊断。相比之下,乳房钼靶检查结合超声检查对乳腺癌的检出率仅为37.5%。这是一个最新发表在Journal of Clinical Oncology杂志上研究的关键发现。该项研究由维也纳医科大学的放射科、核医学科与妇产科和临床病理学研究所联合进行。

“在有丝毫怀疑的情况下,尤其是对于风险增加的女性,显然核磁共振是可取的选择。我们的研究清楚地显示了磁共振成像优于乳房钼靶检查和乳腺超声检查,” 该研究的共同研究者、Thomas Helbich与Christopher Riedl说,“核磁共振的优越性也完全独立于的患者年龄、基因突变状态和乳房密度之外。”

为探讨MRI、乳房钼靶与乳腺超声检查在乳腺癌高危妇女人群中筛查的有效性和实用性,研究人员进行了一项单中心前瞻性的非随机对照研究。该研究以BRCA突变携带者和家族性高危的女性为乳腺癌筛查对象,通过乳房钼靶、超声和MRI每12个月一次检查进行普查。分别对比各个模式及它们的组合之间的诊断性能。此外,研究人员也基于突变状态、年龄、和乳房密度来对高危人群的亚种群进行二分筛查。

这项研究中共有559名女性完成总共1365轮影像学检查。结果显示,核磁共振的敏感性(90.0%)(P<0.001)明显高于乳腺钼靶影检查(37.5%)和超声检查的(37.5%)。在40例乳腺癌中,其中18例(45.0%)单独被核磁共振所检测到。两例乳腺癌仅靠乳房钼靶检查发现 (一例微小侵润性导管原位癌(DCIS)和一例侵润区域<10毫米的DCIS),但这并没有导致乳房钼靶的灵敏度较单独使用MRI显著增加(P=0.15)。单纯靠超声未能发现癌症。同样,14例DCIS全部被MRI检测到,而乳房钼靶检查和超声检测各检测到5例(35.7%)。年龄、突变状态和乳房密度并没有影像核磁共振对检出乳腺癌的敏感性,也并不影响MRI在筛查方面对比乳腺钼靶检查和乳腺超声检查的优越性。

“对于具有强大的乳腺癌家族病史以及手术切除乳房和卵巢需要的女性患者来说,一年一次的核磁共振扫描检查是她们这群高危人群的最佳选择,“Helbich说,“这绝不是过度诊疗,而是一种必要措施。在奥地利仍有大约13000名妇女处在罹患乳腺癌的高风险中。”

Helbich补充说:“这一研究结果,使我们有责任让女人更加意识到这样一个事实:使用乳房钼靶检查和乳腺超声无法检测到所有类型的乳腺癌。MRI是推荐的方法。”

腰椎间盘突出CT和MRI读片技巧

椎间盘突出症是一种多发病,要确诊自己是否患有腰椎间盘突出症,最好的方法是去医院拍一张腰部CT片或者MRI(磁共振片子)。 不过一般医生都没有充裕的时间把片子报告详细解释给你听,患者常常只能拿着“语言简练”的CT或者磁共振报告单对自己的病情似懂非懂。 不要着急~现在就来手把手教你,怎样自己也能看懂CT和MRI磁共振片子,做到自己心中有数。学习本看片教程不需要以前有医学知识背景,只

临床上CT、MRI、PET三种检查的比较

CT(X线电子计算机断层扫描)主要是利用X线断层扫描,电光子探测器接收,并把信号转化为数字输入电子计算机,再由计算机转化为图像,是一种无痛苦、无损伤的辅助检查工具。CT的特点:具有检查方便、安全、无痛苦、无创伤的特点。图像清晰、分辩力高、解剖关系明确、病态显影清楚。与MRI比较起来,CT的优点主要在于对骨性疾病、早期脑出血的显示优于MRI,同时成像速度快,器官的运动伪影较小,CT的优势还在对肺部、

NEJM:颅内压增高为脑型疟疾患儿死因

背景:患脑性疟疾的非洲儿童病死率范围在15%到25%,关键的发病经过和死因尚不明确。但是结合临床观察和病理结果表明,患脑性疟疾的非洲儿童死因很可能是因为脑内容物增加导致颅内压增高。2009年在马拉维可使用核磁共振(MRI)研究,因此,我们使用MRI来探讨并研究脑水肿在脑性疟疾的非洲儿童的发病机制。研究方式:我们对患脑型疟疾的非洲儿童进行了严格的筛选并登记,有详细而明确的脑型疟疾的标准(包括视网膜病

胎儿MRI检查安全吗?

1983年Smith等首次报道应用磁共振成像(Magnetic resonance imaging, MRI)技术对胎儿进行检查,国内应用较晚,始于1995年,近几年才开始越来越多地应用于胎儿各系统的检查,尤其是神经系统,已成为胎儿超声检查的重要补充手段。虽然MRI在胎儿腹部和盆腔的应用较胎儿中枢神经系统和胸部少,但是在超声诊断困难的情况下,MR检查能够提供重要的解剖信息,辅助诊断,帮助和指导

Eur Spine J:短反转时间反转恢复MRI可预判骨质疏松骨折椎体预后

胸腰段骨质疏松椎体骨折可引起剧烈背痛和后继后凸,不愈合和迟发性瘫痪,影响高龄患者的生活质量,甚至致死率增高。预测不愈合情况可帮助筛选出骨质疏松椎体骨折患者并加以防治。 近年来,MRI在诊断椎体骨折方面的重要性日益明显,但MRI预测骨质疏松椎体骨折进展的研究较少。在这方面,有学者报道短反转时间反转恢复MRI(STIR MRI)确定出28例骨质疏松椎体骨折中,普通影像检查未发现的8例骨折。亦
