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.

Cardiac Chambers

Overview

The heart contains four chambers that coordinate blood flow through the pulmonary and systemic circuits. Atria receive venous return and ventricles generate pressure to eject blood into arteries. Chamber size wall thickness and function reflect physiologic and pathologic states.

Right Heart

The right atrium and ventricle handle systemic venous return and pump blood to the lungs. Right heart function depends on pulmonary vascular resistance and tricuspid valve competence. Right sided failure affects systemic venous pressures and organ congestion.

Left Heart

The left atrium receives oxygenated pulmonary venous blood and the left ventricle ejects blood into the aorta. Left ventricular function determines systemic perfusion and cardiac output. Imaging quantifies chamber volumes wall motion and ejection fraction.

Clinical Relevance

Chamber enlargement dysfunction and valvular disease are assessed by echocardiography CT and MRI. Heart failure cardiomyopathy and congenital anomalies affect chamber morphology and function. Targeted therapies address underlying causes and improve outcomes.
