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 ...
To explore the effects of tube voltage, radiation dose and adaptive statistical iterative reconstruction (ASiR-V) strength level on the detection and characterization of pulmonary nodules by an artificial intelligence (AI) software in ultra-low-dose chest CT (ULDCT). Materials and methods An anthro...
The big news of the study, said Diane Stover, MD, from Memorial Sloan-Kettering Medical Center in New York City and President of the Chest Foundation, is that low-dose CT can be used for surveillance in lung cancer. "We don't have a screening tool for lung cancer, which is so importa...

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 ...
According to the corresponding principles or guidelines, the radiation dose received by patients should be in the safe range during nuclear medicine diagnosis and treatment. Radiation can cause deterministic or random effects on the human body. However, dose optimization helps to reduce the radiation ...
Low-dose CT in combination with appropriate diagnostic algorithms has been shown to detect many asymptomatic, small, early stage, resectable NSCLC with a low proportion of invasive procedures for benign lesions. Because of the huge implications of general screening recommendations definite proof of the...
[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 ...
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...
