Case Presentation: A 14 month old female paediatric patient underwent a non-contrast CT scan of their chest post drain tube insertion to the right lung under CT guidance. Multi-planar reconstruction images and 3D rendered images were produced using an iterative reconstruction (IR) technique. The ...

For a chest scan to be considered ‘low-dose’, it should be 2 millisieverts (mSv) or lower, compared to a ‘standard’ lung CT dose of approximately 8 mSv. Scans are considered ‘ultra-low-dose’ if they are <1 mSv; however, these definitions are the subject of debate.41 More ...
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 ...
In addition to methodologically justified decisions, we also decided on the basis of the fact that some relevant pre-existing diseases might potentially be undiagnosed at the time of the initial CT scan. While several pre-existing conditions or comorbidities can certainly be regarded as causally ...
Adipose tissueComputed tomography angiographyMultidetector computed tomographyObjects The purpose was to determine whether the epicardial adipose tissue (EAT) area on low-dose chest CT (LDCT) could be used to predict coronary atherosclerosis in an asymptomatic population......
Each image was labeled as either “1″, if the patient was diagnosed with lung cancer within one year from the scan, or “0” otherwise. This dataset was collected from many different centers that consist of large variations in image quality and acquisition parameters. More specifically, the ...
