Method: In this basic (experimental) study with CT images, 20 patients with different lung disease indications were scanned with ULD and routine dose chest CT protocols. ULD and routine dose CT images were reconstructed utilizing iDose and iterative model reconstructio...
The effective dose (ED) was calculated using a conversion coefficient for the chest 0.017.ResultsOf 42 patients, the image quality was good in 26 cases (62%) and moderate in 16 cases (38%). There was no statistical difference in the CT-attenuation and CNR of left atrium and central ...

In addition to routine evaluation (physical exam, ECG, and chest x-ray), two-dimensional and M-mode echocar- diograms, transcutaneous oxygen monitoring, and single film aor- tograms indicated the correct diagnosis in all except one infant with CHD and in all infants with No nstructural ...
This ultra-low dose chest CT (ULD-CT) has an image quality that is degraded on purpose, yet remains diagnostic in many clinical indications. Thus, its effectiveness is already validated for the detection and the monitoring of solid parenchymal nodules, for the diagnosis and monitoring of ...
detecting different types of lung lesions, such as cancer, using ultra-low dose (ULD) chest CT images.Method: In this basic (experimental) study with computed tomography (CT images), 20 patients with different lung disease indications were scanned with ULD and routine dose chest CT protocols. ...
Clinical relevance statement The study prospectively evaluated the contribution of DLR applied to chest low-dose CT for image quality improvement and lung parenchyma assessment. DLR can be used to reduce radiation dose and keep image quality for several indications....
We report a model for undertaking CTCA with low contrast dose providing excellent image quality and correlation with invasive coronary angiography. Method Over 800 CTCAs have been undertaken at our centre in the last year. We have refined our protocol to deliver an average contrast volume of 30mL...
