While the real-time reverse-transcription polymerase chain reaction test (RT-PCR) is considered the gold standard for the diagnosis of COVD-19, additional low-dose chest computed tomography (LDCT) is often performed, as CT is nearly ubiquitously available for diagnostic of COVID-19 with a high...
Low-dose CT screening for lung cancer with automatic exposure control: phantom study We conducted a study to determine optimal scan conditions for automatic exposure control (AEC) in computed tomography (CT)of low-dose chest screening in or... Shiho,Gomi,Yoshihisa,... - 《Radiological Physics ...
CTscreeninglungcancerROCcurveThe National Lung Screening Trial (NLST) reported a 20% reduction in lung cancer specific mortality using low-dose chest CT (LDCT) compared with chest radiograph (CXR) screening. The high number of false positive screens with LDCT (around 25%) raises concerns. NLST ...
Conclusion There is moderate inter- and intraobserver agreement for nodule classification by using current recommendations for low-radiation-dose CT examinations of the chest. Discrepancies in nodule categorization were mainly caused by disagreement on the size and presence of a solid component, which ...

A systematic review and lessons learned from early lung cancer detection trials using low-dose computed tomography of the chest. Computed tomography (CT) screening of the chest has shown promise for early detection of lung cancer, but evidence for a reduction in lung cancer mortality... G Bepler...
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 ...
[1]. These sequelae may be less frequent in individuals that received at least two doses of a two-dose COVID-19 vaccine regimen [2]. Cardiorespiratory fitness (CRF, herein defined as peak oxygen uptake—\(\dot{V}\)O2peak), a powerful predictor of mortality and risk factor for the ...
We have observed that DLIR provides promising results that are at least as good as those obtained with the ASIR-V reconstruction algorithm in an anthropomorphic study set-up for low-dose chest CT. Essentially, DLIR allows to achieve notable dose reductions of chest CT onto a level of ultra...
A low-dose chest CT exam was performed upon admission in 94.65% (n = 336) of patients. 2.4. Management Treatment initially consisted of hydroxychloroquine (2 × 400 mg day 1, 2 × 200mg day 2–5) as a single agent, but was later modified to include ...
