Reduction of radiation exposure and improvement of image quality with BMI-adapted prospective cardiac computed tomography and iterative reconstruction

Impact of Increasing Levels of Advanced Iterative Reconstruction on Image Quality in Low-Dose Cardiac CT Angiography

“…Thus, IR in combination with an edge-enhancing reconstruction algorithm (i. e. XCB) and "multi-resolution" represents an ideal combination, as high spatial resolution can be combined with a reduction in image noise while preserving an easy-to-adapt image appearance. The results of our study are in good agreement with those from a similar study performed with the iDose prototype, which, however, was restricted to a maximum iDose level of 5 and the use of the XCB kernel only [32]. As a prototype that was not approved as a medical device was used at the point in time when this study was conducted, only the influence of increasing IR levels on image quality at a constant dose could be investigated.…”

Low-dose, wide-detector array thoracic aortic CT angiography using an iterative reconstruction technique results in improved image quality with lower noise and fewer artifacts

“…[4][5][6][7][8][9][10][11][12][13][14][15][16] Along with other dosereduction strategies, IRT allows the user to achieve a balance among radiation dose, spatial and contrast resolutions, and noise. With the same radiation dose used in FBP, IRT can maintain or improve resolution while reducing noise.…”

Quantitative analysis of left ventricular dyssynchrony using cardiac computed tomography versus three-dimensional echocardiography

“…Radiation exposure was relatively high but in the upper range of the recently published PROTECTION I trial and other recently published studies using dual-source CCT [20,37]. In future studies, and according to recent reports the radiation exposure can be reduced markedly by using lowtube voltage (100 kV) acquisitions, BMI-adapted tube current and iterative reconstruction algorithms [38,39].…”
