TLDR
The ASIR reconstruction algorithm is a promising technique for providing diagnostic quality CT images at significantly reduced radiation doses in comparison with low-dose and standard-dose filtered back projection CT.Abstract:
OBJECTIVE. The purpose of this article is to discuss the application of a new CT reconstruction algorithm, adaptive statistical iterative reconstruction (ASIR), to reduce radiation dose at body CT and to provide imaging examples in comparison with low-dose and standard-dose filtered back projection CT.CONCLUSION. The ASIR reconstruction algorithm is a promising technique for providing diagnostic quality CT images at significantly reduced radiation doses.read more

ACG Clinical Guideline: Management of Crohn’s Disease in Adults
Gary R. Lichtenstein,Edward V. Loftus,Kim L. Isaacs,Miguel Regueiro,Lauren B. Gerson,Bruce E. Sands +5 more
TL;DR: This guideline is intended to be flexible, not necessarily indicating the only acceptable approach, and should be distinguished from standards of care that are inflexible and rarely violated.

Iterative reconstruction technique for reducing body radiation dose at CT: feasibility study.

TL;DR: These preliminary results support body CT dose index reductions of 32-65% when adaptive statistical iterative reconstruction is used and suggest that studies with larger statistical samples are needed to confirm these findings.

TL;DR: The facts are summarized about CT scans, which involve much higher doses of radiation than plain films, and the implications for public health are summarized.

TL;DR: The difficulties involved in quantifying the risks of low-dose radiation are reviewed, a linear extrapolation of cancer risks from intermediate to very low doses currently appears to be the most appropriate methodology, and a linearity assumption is not necessarily the most conservative approach.

TL;DR: Concerns arise when CT examinations are used without a proven clinical rationale, when alternative modalities could be used with equal efficacy, or when CT scans are repeated unnecessarily.

Diagnostic CT scans: assessment of patient, physician, and radiologist awareness of radiation dose and possible risks.
TL;DR: Patients are not given information about the risks, benefits, and radiation dose for a CT scan, and patients, ED physicians, and radiologists alike are unable to provide accurate estimates of CT doses regardless of their experience level.
