Vascular Imaging

Feb

Overview

Vascular imaging includes ultrasound CT angiography and MR angiography. It evaluates stenosis occlusion aneurysm and malformations. Imaging guides endovascular and surgical interventions.

Carotid Imaging

Carotid ultrasound assesses plaque and stenosis non invasively. CT and MR angiography provide detailed vascular maps. Findings inform stroke prevention strategies.

Peripheral Vascular

CT angiography and MR angiography evaluate peripheral arterial disease. Ultrasound assesses flow and duplex parameters. Imaging guides revascularization and intervention planning.

Aortic Imaging

CT angiography is the standard for aortic aneurysm assessment. MR angiography offers alternatives in selected patients. Imaging monitors aneurysm size and guides timing of repair.

Cardiac Valves

Overview

Cardiac valves ensure unidirectional blood flow and include the mitral tricuspid aortic and pulmonary valves. Valve leaflets chordae tendineae and papillary muscles coordinate opening and closure during the cardiac cycle. Valve integrity is essential for efficient cardiac function.

Mitral and Tricuspid Valves

The mitral valve controls flow from left atrium to left ventricle and the tricuspid valve from right atrium to right ventricle. Regurgitation or stenosis of these valves affects preload and ventricular loading conditions. Echocardiography evaluates valve morphology and hemodynamic impact.

Aortic and Pulmonary Valves

The aortic valve regulates outflow from the left ventricle to the aorta and the pulmonary valve from the right ventricle to the pulmonary artery. Calcific disease congenital anomalies and endocarditis affect valve function. CT and echo guide intervention planning including valve replacement.

Clinical Relevance

Valvular heart disease causes heart failure arrhythmia and embolic risk. Imaging quantifies severity and guides timing of repair or replacement. Multidisciplinary heart teams optimize patient outcomes.
