Radiology:核磁共振”背景强化“检查可预测女性患乳腺癌风险

我们都知道,常规核磁共振(MRI)检查有助于诊断乳腺癌。不仅如此,一项最新研究发现,MRI检查还有助于女性预测日后患乳腺癌风险。

华盛顿大学医学院的研究人员、放射学家Habib Rahbar发现,高乳腺癌风险女性MRI扫描后,呈现其共有特点——乳腺组织背景区域呈现高亮白色,这种现象在核磁共振技术领域术语称为“背景强化”(background parenchymal enhancement, BPE)——这类人群在接下来的几年患乳腺癌的风险是正常人的9倍。

美国癌症协会建议,女性患乳腺癌风险超过20%,除了要进行常规X光检查,还要进行核磁共振检查。美国女性患乳腺癌风险平均为12%。

另外,携带突变基因BRCA 1和BRCA 2的女性致病风险更高,也会出现家族遗传现象。

研究于5月12日发表在Radiology杂志上。

Ann Neurol:DWI不能很好诊断短暂性脑缺血发作

短暂性脑缺血发作(TIA)的诊断主要依据临床病史,因为神经系统体征常很快消失。核磁共振(MR)弥散加权成像(DWI)对微小缺血灶敏感的优点,有助于诊断短暂性脑缺血发作(TIA),并且TIA伴DWI急性缺血灶阳性的患者,卒中复发风险将会增加。因此DWI既有助于提高TIA的诊断,还能预测短期卒中风险。 目前国家卒中指南建议对TIA患者进行DWI检测。世界卫生组织提出了通过

Stroke:六分钟核磁共振成像可用于评价急性缺血性卒中

背景及目的:对于急性缺血性卒中患者的评价,核磁共振成像(MRI)与计算机断层扫描相比,仍需要进一步提高采集速度。方法:此项前瞻、单中心研究的入选标准为急性缺血性卒中发作24h表现出临床症状的患者。美国国立卫生研究院卒中量表≥3,无MRI禁忌症。回波平面成像(EPI)结合平行采集技术用于3T磁共振(MR)扫描以加速收集速度。2位神经系放射专家独立分析图像。结果:62位患者符合入选标准,22位患者接受

Nat Med:核磁共振技术有望用于疟疾快速诊断

近日,发表在 Nature Medicine 杂志上的一项研究称,一台放在桌上的小设备可以通过检测血液中恶性疟原虫生长过程中产生的疟色素( haemozoin)诊断出疟疾感染。如果该技术能够广泛应用,将有助于偏远地区疟疾的检测和治疗,在这些地方常规的检测手段根本无法发挥作用。 常规检测手段 诊断疟疾感染的常规方法是通过显微镜在患者的血液样本中寻找导致该疾病的恶性疟原虫。这种方法需要一名

PNAS:MRI扫描可测手机使大脑受热方式

  美国科学家最新研究表明,核磁共振(MRI)扫描可以直接测出手机使大脑受热的方式。他们的研究结果发表在了最新一期的《美国国家科学院院刊》上。   世界卫生组织表示,不可能排除手机辐射的有害影响,该辐射被列为一种可能的人类致癌物。不确定的原因之一是,我们尚未得知辐射如何影响脑组织。   大多数科学家都认为,手机发出的微波辐射会使人体组织受热,就像微波炉加热肉类一样,但对人类大脑内的温度没有精确

Ann Surg:高分辨魔角旋转核磁共振或可用于结直肠癌分期及治疗

研究要点: 研究样本为肿瘤中心部位以及切缘周边5cm的新鲜组织样本 HR-MAS NMR检测可检出CRC肿瘤特异性代谢特征 结肠癌与直肠癌间具有代谢差异 不同T分期肿瘤间的代谢特征也分别具有独特性 既往研究证明,肿瘤细胞具有独特的代谢特征。基于该观点,伦敦大学帝国理工学院Jeremy K. Nicholson博士等人欲通过高分辨魔角旋转核磁共振(HR-MAS NMR)频谱手段,对结直

JNCI:核磁共振筛查可改善有乳腺癌家族史女性的预后

不同年龄段确诊肿瘤和治疗的花费 研究要点: 1.转移性病变造成乳腺癌患者死亡的主要原因,肿瘤转移的风险与发现时肿瘤的大小和受累的腋淋巴结数量相关,因此,早期诊断是至关重要的。 2.对于年轻的女性而言钼靶并非理想的筛查方法,采用何种方法进行评价目前还存在争议。 3.在具有乳腺癌家族史的女性中行核磁共振筛查能改善其预后,但在年轻女性中,会带来
