Comparative Study
Dose reduction in oncological staging multidetector CT: effect of iterative reconstruction.
To compare radiation exposure and image quality of oncological staging multidetector CT (MDCT) examinations of the chest, abdomen and pelvis with and without iterative reconstruction (IR). ⋯ The algorithm tested in the present scientific study allows a >45% dose reduction at maintained image quality.

To compare image quality and radiation dose of abdominal CT examinations reconstructed with three image reconstruction techniques. ⋯ CT images reconstructed with FBP are frequently noisy on lowering the radiation dose. Newer iterative reconstruction techniques have different approaches to produce images with less noise; ASiR and IRIS provide diagnostic abdominal CT images with reduced image noise and radiation dose compared with FBP. This has been documented in this study.
