Iterative Reconstruction Technique for Reducing Body ...
Objective: The purpose of this study was to evaluate the image noise, low-contrast resolution, image quality, and spatial resolution of adaptive statistical iterative reconstruction in low-dose body CT. Materials and methods: Adaptive statistical iterative reconstruction was used to scan the American College of Radiology phantom at the American College of Radiology reference value and at one ......
Emergency assessment of patients with acute abdominal pain ...
To determine if radiation dose delivered by contrast-enhanced CT (CECT) for acute abdominal pain can be reduced to the dose administered in abdominal radiography (<2.5 mSv) using low-dose CT (LDCT) with iterative reconstruction algorithms. One hundred and fifty-one consecutive patients requiring CECT for acute abdominal pain were included, and their body mass index (BMI) was calculated.

 Iterative Reconstruction Technique for Reducing Body ...
Quantitative Analysis Two abdominal imaging fellows not involved in qualitative data analysis made quantitative noise measurements on a total of 36 data sets: 12 low-dose CT without adaptive statistical iterative reconstruction, 12 low-dose CT with adaptive sta-tistical iterative reconstruction, and 12 routine-dose comparison CT....
Comparative assessment of three image reconstruction ...
Methods: In this Institutional Review Board-approved study, contrast-enhanced (CE) abdominopelvic CT scans from 23 patients were reconstructed using filtered back projection (FBP), adaptive statistical iterative reconstruction (ASiR) and iterative reconstruction in image space (IRIS) and were reviewed by two blinded readers....
