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 ...
Purpose To determine the diagnostic capability of low-dose CT (50 mAs) in comparison to standard-dose CT (150 mAs). Materials and methods Fifty-nine consecutive patients underwent two non-contrast chest CT scans with different current-time products (50 and 150 mAs at 120 kVp) on a 64-detec...
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 ...
“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 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...
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 ...
"This is a preliminary study and further research with larger cohorts of patients is needed. However, it is a good starting point in demonstrating that radiation dose from chest CT's can be significantly reduced without compromising accuracy or reliability of anatomic evaluation. In preoperative pati...
