Radiation exposure and image quality in staged low-dose protocols for coronary dual-source CT angiography: a randomized comparison
 |
To evaluate staged low-dose approaches for coronary CT angiography (CTA) in which a standard sequence was added if the low-dose sequence did not allow reliable rule-out of coronary stenosis. Read more

Evaluation of coronary stents and stenoses at different heart rates with dual source spiral CT (DSCT)
|
|
The utilization of dual source computed tomography (DSCT) might improve the visualization of the coronary arteries by imaging at a temporal resolution of 83 milliseconds, independent of heart rate. Read more

Detection of coronary artery stenoses by low-dose, prospectively ECG-triggered, high-pitch spiral coronary CT angiography
|
|
We sought to evaluate the diagnostic accuracy of a new prospectively electrocardiogram (ECG)-triggered high-pitch scan mode for coronary CTA, which allows an effective dose of less than 1 mSv. Read more

Comparison of Iterative and Filtered Back Projection Image Reconstruction Techniques for the Evaluation of Heavily Calcified Vessels with Coronary CT Angiography
 |
Iterative image reconstruction techniques appear superior to FBP for the evaluation of heavily calcified vessels with cCTA and should be preferentially used in patients with high calcium scores. Read more

Diagnostic accuracy of high-pitch dual-source CT for the assessment of coronary stenoses: first experience
 |
The objective was to prospectively investigate the diagnostic accuracy of high-pitch (HP) DSCT coronary angiography (CTCA) compared with catheter coronary angiography (CCA) for the diagnosis of significant coronary stenoses. Read more
