[CT coronary angiography: indications, image acquisition, and interpretation]

Cardiac CT has advanced beyond experimental use into clinical practice. It is now a viable alternative to invasive catheterization for specific patient groups. Prior research has shown that CT can evaluate coronary anatomy and detect anomalies. Atypical chest pain is one condition where CT has proven useful. Before surgical interventions, CT provides detailed morphological data. Coronary revascularization outcomes can also be assessed with this modality. Emergency departments are exploring CT for acute chest pain evaluation. However, the heart's constant motion complicates image acquisition. Rapid technological progress requires frequent protocol adjustments. Users familiar with CT fundamentals can adapt to these changes.

This article aims to guide practitioners in performing CT coronary angiography. It addresses challenges like motion artifacts and contrast enhancement. The authors seek to standardize patient selection and imaging protocols. They emphasize the importance of radiation safety and medication protocols. The goal is to provide step-by-step guidance for image acquisition. The article also covers reconstruction and analysis techniques. It includes recommendations based on evolving CT technology. The focus is on practical implementation in clinical settings.

The authors describe a step-by-step approach to CT coronary angiography. They include patient selection criteria and pre-procedure medication use. Radiation protection strategies are outlined to minimize exposure. Contrast administration protocols are detailed for optimal enhancement. Acquisition parameters are adjusted based on scanner capabilities. Dual-source CT is highlighted as a preferred modality. Image reconstruction techniques are discussed for clarity. The radiological report structure is also explained.

The authors present a comprehensive protocol for CT coronary angiography. They emphasize dual-source CT as a preferred acquisition method. Patient selection and pre-medication are critical for success. Contrast enhancement is optimized using specific timing protocols. Image reconstruction is tailored to reduce motion artifacts. Radiation dose is minimized through protective measures. Image analysis techniques are detailed for accurate interpretation. The radiological report format is standardized for consistency.

The authors conclude that CT coronary angiography is a mature clinical tool. It can replace invasive catheterization in certain cases. Dual-source CT is recommended for routine clinical use. Proper patient selection and medication are essential. Radiation safety remains a priority in imaging protocols. Contrast enhancement and timing are key to image quality. Image reconstruction and analysis require specific techniques. The radiological report format ensures consistent documentation.
