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 ...
in Cleveland, OH. Researchers evaluated 29 patients who underwent prospectively-gated 100 kV whole chest CT for preoperative cardiothoracic surgery. The meanradiation dosewas determined and compared to a group of regular dose prospectively-gated exams. "The most significant aspect of our...
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...
Conclusion Low dose CT protocol at 50 mAs can produce the screening results consistent with standard dose CT protocol (150 mAs), supporting routine use of low dose chest CT protocol 展开 关键词: Radiation dose reduction Chest CT Diagnostic accuracy ...

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)...
Three CT scans were obtained at each dose level using both rings. Regions of interest for each material in the test object scans were automatically extracted. The Hounsfield unit values of each material using weighted filtered back projection (WFBP) at 1.5 mGy was used as the reference value ...
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...
Cancer patients have a higher risk of cardiovascular disease (CVD) mortality than the general population. Low dose computed tomography (LDCT) for lung cancer screening offers an opportunity for simultaneous CVD risk estimation in at-risk patients. Our de
Fig. 1. (a, standard dose image; b, low dose image) 75 year-old-male (body weight 46 kg) who had a chest CT examination for a suspected lung tumor in the right upper lobe. Visualization of a tumor with partially irregular margin and spicula (arrow) is clear in both images. Downloa...
