Abstract

Since the authors are not responding to the editor’s requests to fulfill the editorial requirement, the article has been withdrawn.

Bentham Science apologizes to the readers of the journal for any inconvenience this may have caused. The Bentham Editorial Policy on Article Withdrawal can be found at https://benthamscience.com/editorial-policies-main.php

Bentham science disclaimer: It is a condition of publication that manuscripts submitted to this journal have not been published and will not be simultaneously submitted or published elsewhere. Furthermore, any data, illustration, structure, or table that has been published elsewhere must be reported, and copyright permission for reproduction must be obtained. Plagiarism is strictly forbidden, and by submitting the article for publication, the authors agree that the publishers have the legal right to take appropriate action against the authors if plagiarism or fabricated information is discovered. By submitting a manuscript, the authors agree that the copyright of their article is transferred to the publishers if and when the article is accepted for publication.

利用双层光谱检测器CT衍生的电子密度图像评估非增强CT图像上的肺栓塞:一项在急诊科进行的单中心前瞻性研究
目的评估非增强光谱成像、电子密度(ED)和覆盖电子密度(OED)图像在评估疑似或确诊急性肺栓塞(APE)患者肺栓塞中的应用价值。从光谱检测器CT (SDCT)、ED和OED图像中可以推断出多光谱图像。ED和OED图像对富含水分的组织高度敏感。在非增强胸部CT图像中检测肺动脉血栓的潜在用途。目的评价SDCT非增强图像上ED和OED图像检测肺栓塞的敏感性、特异性和准确性。方法回顾性研究于2021年11月至2022年4月期间,采用双层光谱检测器CT进行非增强和CT肺血管造影评估APE的79例患者。根据未增强的光谱和CTPA图像,两名放射科医生在ED和OED图像上确定了主要、大叶和节段肺动脉的高密度区域,并使用咨询方法在增强图像上检测肺栓塞(PE)。CTPA结果被认为是金标准。分析ED和OED对PE的诊断效果。结果40例(40/79)患者检出PE,其中主动脉17例,大叶动脉69例,节段动脉20例。PE在ED图像上的灵敏度为69.7-94.7%,特异性为58.5-98.2%。对OED影像的敏感性为94.1 ~ 95.2%,特异性为80.0 ~ 98.1%。ED影像的阳性预测值(PPV)为53.6 ~ 87.7%,阴性预测值(NPV)为69.7 ~ 95.9%,OED影像的阳性预测值为48.5 ~ 88.9%,阴性预测值为94.1 ~ 98.9%。ED和OED的准确率分别为76.0 ~ 98.9%和87.3 ~ 96.2%。研究发现,无论是有血栓的肺动脉主干、肺叶还是肺节段动脉,EDW值在108.1- 108.8%之间,比无血栓的动脉EDW值高3.9- 4.2%。栓塞肺动脉ED标准化值为103.6- 104.3% EDW。结论不使用造影剂的频谱CT诊断ED和OED具有较高的诊断价值,可提高PE的可视化程度。
