Cardiac CT

Feb

Overview

Cardiac CT provides non invasive assessment of coronary arteries and cardiac structures. It is used for calcium scoring and coronary CT angiography. It aids in risk stratification and procedural planning.

Acquisition Techniques

ECG gating and dose modulation optimize cardiac CT studies. Contrast timing and bolus tracking improve coronary opacification. Heart rate control may be used to improve image quality.

Clinical Indications

Indications include chest pain evaluation and pre procedural planning. Cardiac CT helps assess coronary anomalies and bypass grafts. It complements functional testing and invasive angiography.

Limitations and Safety

Radiation dose and contrast nephropathy are considerations in cardiac CT. Patient selection and protocol optimization mitigate risks. Alternative modalities may be preferred in some patients.

Cardiac Imaging

Overview

Cardiac imaging includes echocardiography CT MRI and nuclear techniques. It evaluates structure function and perfusion. It guides management of cardiac disease.

Echocardiography

Echocardiography uses ultrasound to assess cardiac function. It is portable and provides real time hemodynamic information. It is central to heart failure and valve disease evaluation.

Cardiac CT

Cardiac CT assesses coronary anatomy and calcium scoring. It provides non invasive coronary evaluation. It aids in planning interventions and surgery.

Cardiac MRI

Cardiac MRI offers detailed tissue characterization and function assessment. It is useful for cardiomyopathy and myocarditis evaluation. It complements other cardiac imaging modalities.
