Effect of 70-kVp chest CT on surface dose at the mammary gland level in a neonatal phantom under matched CTDIvol conditions

Radiological Physics and Technology
To compare surface dose at the mammary gland level between 70- and 120-kVp non-contrast neonatal chest computed tomography (CT) under matched volume CT dose index (CTDIvol) conditions, a neonatal anthropomorphic phantom was scanned using a 256-row CT scanner.

Impact of Artificial Intelligence on Dose Reduction: Evaluating AIdriven Image Reconstruction to Lower CTDIvol without Increasing Image Noise

International Journal of Drug Delivery Technology
Objective: To evaluate whether a novel AI-driven image reconstruction algorithm can enable a reduction in CTDIvol without increasing image noise, compared to a standard hybrid iterative reconstruction (IR) algorithm. Methods: A prospective, intra-individual controlled study was conducted on 54 adult patients (mean age 56.3 ± 12.4 years, 29 male ...
