Non-contrast cerebral computed tomography (CT) is frequently performed as a first-line diagnostic approach in patients with suspected ischemic stroke. The purpose of this study was to evaluate the ...

Computed tomography (CT) scans are responsible for more than two thirds of the total radiation dose associated with medical imaging exams. However, a newly adapted low-dose technique called adaptive ...

Estimated radiation doses are substantially lower for pediatric CT exams of the brain that used an adaptive statistical iterative reconstruction technique (ASIR) compared to those that did not use ...

Radiologists can interpret CT images made with iterative reconstruction as accurately as images made with filtered back projection, a new study shows. "Iterative reconstruction improves image quality ...

CT has become a routine imaging modality based on its excellent ability of displaying lung structures and diseases. But, how to reduce radiation dose of routine CT examination is a concern for ...
