in a small number of patients, may indicate the earliest stages of the disease. LDCT uses less than a quarter of the radiation of a conventional CT scan.
Background: Contrast-enhanced chest computed tomography (CT) is useful for the detection and follow-up of patients with lung cancer. However, reaching balance between diagnostic image quality, radiation dose, and iodixanol dose is a cause of concern. Objectives: To invest...
Low radiation dose computed tomography (CT) has been shown to have a much higher sensitivity for small pulmonary nodules, which are believed to be the most common presentation of early lung cancer. As, however, small pulmonary nodules are common and most are not malignant, non-invasive ...
To evaluate the feasibility of using a whole-body photon-counting detector (PCD) CT scanner for low-dose lung cancer screening compared to a conventional energy integrating detector (EID) system. Radiation dose-matched EID and PCD scans of the COPDGene 2 phantom were acquired at different radiati...
TU-H-207A-08: Estimating Radiation Dose From Low-Dose Lung Cancer Screening CT Exams Using Tube Current Modulation Purpose:The purpose of this work is to estimate effective and lung doses from a low-dose lung cancer screening CT protocol using Tube Current Modulation (T... A Hardy,M Bostan...
AlgoMedica is a Sunnyvale-based company using deep learning reconstruction technology to deliver high-quality CT scan with low radiation dosage.

For the aspect of each coronary branches, correlation is lowest (r = 215) in posterior descending artery but high enough in other coronary branches (r > 0.654). CONCLUSION In spit of using low radiation dose and un-gated scan, lung cancer screening CT can detect CAC and proved results of...
The aim of our study was to assess the image quality, radiation dose, and clinical applicability of low-dose, volumetric helical CT in the evaluation of bronchiectasis. Volumetric helical CT scans (120 kVp, 3-mm collimation, pitch of 2, and reconstruction interval of 2 mm) were obtained thro...
An ultra-low dose (ULD) method for CT-guided lung lesion biopsies was implemented.A 57.5% reduction in radiation dose was achieved for the ULD protocol.ACR... S Adiga,S Athreya - 《Clinical Radiology》 被引量: 17发表: 2014年 Safety, efficacy, and feasibility of an ultra-low dose radiati...
