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.

MR Angiography MRA

Feb

Overview

MRA uses flow sensitive sequences or gadolinium contrast to depict vascular anatomy and flow characteristics without ionizing radiation.

Technique

Time of flight phase contrast and contrast enhanced MRA each have strengths for different vascular territories.

Clinical Uses

Cerebral carotid renal and peripheral vascular assessment and evaluation of vascular malformations.

Limitations and Safety

Gadolinium risks in severe renal impairment and lower spatial resolution than CTA in some settings.
