radiation doseBackground: Radiation dose administration and its associated risks when performing computed tomography (CT) has been increasingly scrutinised in the recent past. The absorbed dose to organs and tissue in CT is high, therefore risks must be outweighed by benefit when considering a CT ...

试验详情 试验目的 This study aims to develop a novel ultra-low dose chest CT technology for use in Hereditary Hemorrhagic Teleangiectasia (HHT) patients and to determine the lowest possible radiation dose that is achievable without sacrificing the diagnostic quality. 试验详情 ...
本文提出了一种利用两个连续卷积神经网络在低剂量胸部CT中自动检测冠状动脉、胸主动脉和心脏瓣膜钙化点的方法。第一个网络根据潜在钙化点的解剖位置来识别和标记潜在钙化点,第二个网络识别检测到的候选钙化点中的真实钙化点。 这种方法是在国家肺... 查看原文 ...

Objective To assess the program of low dose chest CT screening with iterative reconstruction technique(iDose4).Methods Totally 120 subjects who underwent chest CT screening were divided into 3 groups according to body mass index(BMI): Group A(BMI≤22),group B(22BMI26) and group C(BMI≥26)...
Thin-section, high-resolution (1.0/1.5 mm thick slices), low-dose chest CT scans were performed in 55 infants and children. The studies were carried out with 1-and 2-s scan (data acquisition) times using a high-resolution (bone) algorithm. Although there was some motion artifact, the stu...
As used herein, the term “urgent hospitalization for angina requiring coronary revascularization” refers to an immediate need for a patient to be hospitalized due to severe chest discomfort felt due to ischemic heart disease which requires surgical intervention grafting and/or stenting approaches to ...
Low-dose computed tomography (LDCT) of the chest is a recommended diagnostic tool in early stage of COVID-19 pneumonia. High age, several comorbidities as well as poor physical fitness can negatively influence the outcome within COVID-19 infection. We investigated whether the ratio of fat to ...
