When working with cardiac imaging, a set of medical imaging techniques that visualize the structure and function of the heart. Also known as heart imaging, it helps clinicians diagnose, monitor, and treat cardiovascular conditions. Cardiac imaging encompasses several sub‑modalities, each suited for different clinical questions.
Echocardiography, ultrasound‑based imaging that captures real‑time heart motion is often the first line test because it’s quick, safe, and reveals valve function, chamber size, and ejection fraction. Cardiac MRI, high‑resolution magnetic resonance scans that detail tissue characteristics requires magnetic resonance technology and excels at detecting fibrosis, cardiomyopathies, and congenital anomalies. CT angiography, contrast‑enhanced computed tomography that maps coronary arteries influences diagnosis of coronary artery disease by showing plaque burden and stenosis. Nuclear cardiology, radioisotope scans that assess perfusion and viability provides functional data that guides treatment for heart failure and ischemia.
These techniques don’t work in isolation. For example, stress testing often pairs with imaging to evaluate hypertension‑related heart changes, while contrast agents improve CT clarity in patients with renal concerns. The interplay of structure (echo, MRI, CT) and function (nuclear scans, stress echo) creates a comprehensive picture that drives personalized therapy.
Below you’ll find articles that dive deeper into each modality, compare their strengths, and link them to common heart conditions such as heart failure, hypertension, and coronary artery disease. Whether you’re a patient looking for clear explanations or a professional needing quick reference points, the collection ahead provides practical insights you can act on.
