Plos One:具有FOV的超高分辨率计算机断层扫描能够提高对肺结节的诊断率?

近期,一项发表在杂志Plos One上的研究旨在评估使用具有小扫描视场(FOV)的超高分辨率CT(UHRCT)扫描的CT成像能否提供更高的图像质量,并且与传统高分辨率CT(CHRCT)扫描相比,能否有助于减少随访周期。研究者们自2015年7月至2015年11月招募至少一个肺结节的患者。在所有入选患者中进行CHRCT和UHRCT扫描。由三位经验丰富的放射科医生使用5分评分评估图像质量并作出诊断。以随

近期,一项发表在杂志Plos One上的研究旨在评估使用具有小扫描视场(FOV)的超高分辨率CT(UHRCT)扫描的CT成像能否提供更高的图像质量,并且与传统高分辨率CT(CHRCT)扫描相比,能否有助于减少随访周期。

研究者们自2015年7月至2015年11月招募至少一个肺结节的患者。在所有入选患者中进行CHRCT和UHRCT扫描。由三位经验丰富的放射科医生使用5分评分评估图像质量并作出诊断。以随机方式同时显示配对的图像,并且去除扫描信息的注释。评估了以下参数:图像质量,放射科医师的诊断置信度,随访建议和诊断准确性。

此项研究共纳入52例患者(62个结节)。与CHRCT相比,UHRCT扫描提供了更好的结节边界和实性结节内部成分的图像质量(P <0.05)。阅片专家对UHRCT图像的诊断可信度较CHRCT图像更高(P <0.05)。随访建议在UHRCT和CHRCT图像之间有显着差异(P <0.05)。与手术病理结果相比,UHRCT的诊断准确率高于CHRCT(P> 0.05)。

这些研究结果表明与CHRCT相比,UHRCT原型扫描仪可以对亚实性结节提供更好的图像质量,也可以显着减少患者的随访周期。

综述:双源CTVNC技术在诊断隐匿性骨折中的应用进展

作者:陈婷婷,刘白鹭,哈尔滨医科大学附属第二医院CT室 隐匿性骨折是指不易被传统影像学检查方法发现而实际存在的细微骨折,临床上容易漏诊。如果诊断不及时,可能会延误治疗、影响治疗效果,若错过治疗时机可造成不可逆的局部松质骨坏死、退行性骨关节病以及骨软骨缺损等严重后果。所以提高隐匿性骨折的检出率十分必要。 隐匿性骨折(骨挫伤)由于松质骨骨小梁微观压缩断裂导致骨髓水肿(BME),

CHEST:医生就比电脑牛!肺结节的良恶性还是医生评估的准!

肺结节的年发病率估计为157万。指南建议使用对恶性结节概率(pCA)的初步评估。以前的研究发现,尽管指南推荐这个建议,但是很多医生没有遵循指南。近期,一项发表在CHEST杂志上的文章研究了对肺结节诊断和检查的现状。此项研究基于最终诊断,对337例患者的肺结节的良恶属性分别进行医师评估(n=337)和此前确定的风险模型评估,并对两者进行比较。医师评估pCA分为低,中和高风险,并评估下一个诊断检查。研

来自德国的研究人员开展了一项前瞻性随机化单中心研究,该研究的目的是评估有中等概率冠状动脉疾病的患者是否应该接受有创冠状动脉造影或计算机断层扫描(CT)。该研究在德国的大学医院进行。该研究共包括340例疑似冠状动脉疾病患者,基于非典型心绞痛或胸痛具有冠状动脉造影的临床适应症。168例患者被随机分配接受CT,172例患者接受冠状动脉造影。随机化后,1例患者拒绝CT,10例患者拒绝接受冠状动脉造影,最后
