Cardiac imaging refers to a variety of techniques used to visualize the heart's structure and function. Common methods include echocardiography, cardiac MRI, and CT angiography. These imaging techniques help doctors diagnose heart conditions, assess blood flow, and evaluate the effectiveness of treatments. These imaging modalities provide detailed information about the heart's chambers, valves, and blood vessels. By using ultrasound, magnetic resonance, or computed tomography, healthcare professionals can identify issues such as heart disease, congenital heart defects, and valvular disorders, ultimately guiding patient management and treatment decisions.
