Article Synopsis
- - The study aimed to compare the image quality, contrast medium volume, and radiation dose between high-pitch and low-pitch renal computed tomography angiography (CTA).
- - Fifty patients were scanned using high-pitch settings with less contrast medium and another fifty with low-pitch settings, finding no significant difference in image quality but a significantly lower radiation dose in the high-pitch group.
- - The results suggest that high-pitch scanning can achieve similar image quality as low-pitch while using less contrast medium and reducing radiation exposure.
Objective: To evaluate the performance of sinogram-affirmed iterative (SAFIRE) reconstruction on image quality of low-dose lung computed tomographic (CT) screening compared with filtered back projection (FBP).
Methods: Three hundred four patients for annual low-dose lung CT screening were examined by a dual-source CT system at 120 kilovolt (peak) with reference tube current of 40 mA·s. Six image serials were reconstructed, including one data set of FBP and 5 data sets of SAFIRE with different reconstruction strengths from 1 to 5.
Objectives: To evaluate the capability of spectral CT imaging to detect the different stages and angiogenesis of myocardial infarction (MI).
Methods: MI was surgically induced in 40 rabbits that were evenly divided into four stages of MI: 6 h (6H), 3 days (3D), 7 days (7D) and 14 days (14D). Spectral CT was performed at 10 s, 1 min and 3 min after intravenous contrast medium administration.
Contrast media volume optimization in high-pitch dual-source CT coronary angiography: feasibility study.
Int J Cardiovasc Imaging
January 2013
To investigate the feasibility of contrast media (CM) volume reduction in dual-source coronary computed tomography angiography high-pitch mode without affecting coronary artery enhancement. Eighty patients were involved in a preliminary experiment with a default injection protocol (60 ml of CM). The age, BMI, test bolus (TB) enhancement peak and the CT values of coronary artery for each patient were recorded and the key factors for determining coronary artery enhancement were investigated.
