International PRospective Multicenter Study On RadiaTion Dose Estimates Of Coronary CT AngIOgraphy IN Daily Practice — PROTECTION-I  

Coronary Disease Clinical Trial

Official title:
International PRospective Multicenter Study On RadiaTion Dose Estimates Of Coronary CT AngIOgraphy IN Daily Practice

Clinical Trial Summary

Estimation of radiation dose of coronary multislice computed tomography (MSCT) angiography in daily practice in an international, multicenter and vendor-independent trial.

Clinical Trial Description

Prospective analysis of cardiac CT angiographies enrolled over 1 month

Collection of 1 axial data set and the "patient dose protocol" (including kV, mAs, CTDI, DLP, etc.) on a CD

Dose estimation in dose/cm with the use of a method proposed by the European Working Group for Guidelines on Quality Criteria in CT.

Assessment of diagnostic, qualitative image quality on a per-vessel basis by the participating study sites and in randomly selected cases by the primary study investigators (approximately 5-10% of patients to "spot check" interobserver variability of image quality assessments)

Assessment of image quality with the use of quantitative parameters including image noise, signal-to-noise and contrast-to-noise ratios ;

Study Design

Observational Model: Case-Only, Time Perspective: Prospective
