Radiation Dose Reduction with Hybrid Iterative Reconstruction for Pediatric CT - Article Review

Radiation Dose Reduction with Hybrid Iterative Reconstruction for Pediatric CT - Article Review

Introduction

The article penned by Singh (2012) was conducted to assess the importance of abdominal computed tomographic (CT) data and the images produced by it and the decline in the radiation dose as a consequence of it. This assessment of the data was made in reference to FBP or filtered back projection. The paper presents the analysis of the article and summarizes the findings of the article. This has been done in reference to the most important points in the article which are given in the appendix section.

Article Analysis

The need for conducting the research stems from the fact that more lately, there have been increasing concerns on the safety of use of dose in computed tomography. This was of major concern especially in children. The use of dosage determines the exposure to radiation for the person during the computed tomography scan. The best method to decrease exposure to radiation is to decrease the dosage associated with CT scan.

In order to compare FBR with ASIR, the research term working on the article collected a sample of 235 patients which varied widely in their ages. The selected group was of people aged as low as 6 weeks and went up to 18 years. This sample was selected carefully to ensure representation of the population. This was assessed for pediatric, abdominal and chest data. The retrospective study that was conducted by the research was complied as per the rules given by HIPAA. ASIR or adaptive statistical iterative reconstruction that was used for CT scan in this research was hybrid in its nature and construction and enabled 64 detector row.

On comparing FBR with ASIR, it can be seen that ...
