本研究旨在评价基于迭代算法模型的CT颅脑重建技术在检出脑转移瘤的价值,并将结果发表在Eur Radiol上。

本研究共纳入了115例经组织病理学证实为肺癌的患者,并采用256层MD在初始阶段行标准剂量(CTDIvol: 41.4 mGy)和50%标准剂量(CTDIvol: 20.7 mGy)两次CT扫描。两次扫描图像均采用滤过反向投影(FBP)和基于迭代模型重建(IMR)算法进行重建。以颅脑MRI作为参考标准。两名阅片者独立分析图像。

共有93例患者进行所有的检查。在标准剂量时,8例患者的IMR和FBP CT图像共分别发现17、15处病变。在50%标准剂量时,7例患者的IMR和FBP CT图像共分别发现15/13处病变。两种算法检查病灶的差异无统计学意义(p-value = 0.12)。在MRI图像上,11患者共发现46处转移病灶。CT检出转移病灶的特异性、阴性预测值和阳性预测值分别为98.9-100%、93.6-94.6%、75-100%。

本研究表明,在CT的两种重建方法间显示转移瘤病灶的价值并无显着性差异。

Eur Radiol:肺毛霉菌病:CT图像上影像学改变与临床和病理间的相关性

肺毛霉病(puhmonary mucormycosis)是由毛霉菌目致病菌引起的肺感染性疾病。虽然少见,但发展迅速,死亡率高。临床上以毛霉菌和根霉菌较为常见,前者主要侵犯肺,后者多累及到鼻窦、眼、脑及消化道,并可血行播散到全身。肺毛霉菌病可为原发感染,也可继发于鼻窦病变或毛霉菌败血症。本研究为了评价肺毛霉菌病CT的动态变化和外周血嗜中性粒细胞绝对计数(ANC)的相关性,并将结果发表在Eur Rad

Hepatology:CT和MRI对诊断肝细胞癌的的优劣

多相计算机断层扫描(CT)和磁共振成像(MRI)均可用于肝硬化肝细胞癌患者(HCC)的非侵入性诊断。近期,一项发表在杂志Hepatology上的研究旨在确定这两者之间是否存在相对的诊断优势,研究者们综合了CT,细胞外对比增强MRI和钆素增强MRI对肝硬化患者HCC诊断的相关性能的证据。此外,还评估了肝活检与对照替代成像的随访是否适用于肝硬化患者的CT或MRI不确定性肝结节。研究者们检索至2016年

Invest Radiol:光栅型相位对比CT对心肌结构改变的定性和定量分析的价值

Invest Radiol:在特发性肺纤维化患者中残存正常肺实质呼气相密度增高可能是病变蔓延的表现

特发性肺纤维化(IPF)是一种慢性进展性致死性肺疾病,目前病理机制尚不明确。影像学特点类似常见间质性肺炎,逐渐累及残存正常肺实质外周和底部。有一种假说是肺泡破裂后肺实质发生纤维化。本研究旨在探究正常表现的肺组织在呼气相时的破裂征象和与其他肺疾病及健康志愿者的差异,并将结果发表在Invest Radiol上。

Radiology:双源CT模拟Noncalcium技术在检出多发性骨髓瘤患者脊柱和盆腔骨质浸润诊断准确性

多发性骨髓瘤是恶性浆细胞病中最常见的一种类型,又称骨髓瘤、浆细胞骨髓瘤或Kahler病。虽然早在1844年对此病已有人作出描述,但直到1889年经Kahler详细报告病例后,多发性骨髓瘤才普遍为人们所了解和承认。多发性骨髓瘤的特征是单克隆浆细胞恶性增殖并分泌大量单克隆免疫球蛋白。恶性浆细胞无节制地增生、广泛浸润和大量单克隆免疫球蛋白的出现及沉积,正常多克隆浆细胞增生和多克隆免疫球蛋白分泌受到抑制,

Radiology:CT表现预测结肠憩室炎复发的价值。

结肠憩室是指肠粘膜经肠壁肌层缺损处向外形成囊状突出的病理结构。多个憩室的存在则称之为结肠憩室病。憩室绝大多数为后天形成的。结肠憩室炎急性发作时有程度不同的局限性腹部疼痛,可呈刺痛、钝痛和绞痛,大多疼痛部位都在左下腹,偶尔位于耻骨上、右下腹或整个下腹部。炎症邻接膀胱可产生尿频、尿急。根据炎症部位和严重性还可伴有恶心和呕吐。本研究旨在评价CT表现预测结肠憩室炎复发的价值并将结果发表在Radiology
