There was no statistically significant difference in the deviation of the observers' scores between low-dose CT and standard-dose CT. Low dose CT protocol at 50mAs can produce the screening results consistent with standard dose CT protocol (150mAs), supporting routine use of low dose chest CT ...

The purpose of this study was to evaluate the impact of ultralow radiation dose single-energy computed tomographic (CT) acquisitions with Sn prefiltration and third-generation iterative reconstruction on density-based quantitative measures of growing interest in phenotyping pulmonary disease. The effects ...
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)...
Low-dose chest CT scan protocol The image acquisition and analysis for the ImaLife study has been previously published30. ImaLife participants undergo a two-part low-dose CT using a third-generation dual- source CT scanner (SOMATOM Force, Siemens Healthineers, Germany). Firstly, participants under...
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...
An ultra-low dose (ULD) method for CT-guided lung lesion biopsies was implemented.A 57.5% reduction in radiation dose was achieved for the ULD protocol.ACR... Adiga,S.,Athreya - CLINICAL RADIOLOGY-EDINBURGH- 被引量: 16发表: 2014年 Efficacy and Radiation Exposure of Ultra-Low-Dose Chest CT...
dose chest CT that results in a radiation dose reduction of 42% when compared with traditional dose chest CT exams. In an era of heightened awareness ofradiation exposureto patients frommedical imaging, this is a significant finding," said Sonali Mehandru, MD, one of the authors of the ...
“We could clearly detect the increase of DNA damage and chromosome aberrations after standard chest CT,” says senior author Satoshi Tashiro from Hiroshima University. “In contrast, even using these sensitive analyses, we could not detect the biological effects of low-dose CT scans. This suggests...
Objective:To explore the value of low dose chest CT scan in evaluating the therapeutic effect of pulmonary tuberculosis.Methods:76 cases of pulmonary tuberculosis were treated,and the experimental group(with 37 cases) was discontinued according to the CT scan,and the control group(with 39 cases) ...
