Interobserver agreement for the detection of atherosclerotic plaque in coronary CT angiography: comparison of two low-dose image acquisition protocols with standard retrospectively ECG-gated reconstruction.

摘要

? Low-dose CT protocols permit coronary plaque detection with good interobserver agreement. ? Image noise is a major predictor of interobserver variability. ? Interobserver agreement is significantly higher for calcified than for non-calcified plaque.
