What procedure is used to visualize lesions in blood vessels by injecting contrast material?

The procedure that is used to visualize lesions in blood vessels by injecting contrast material is neuroangiography. This technique specifically focuses on the blood vessels of the brain and other parts of the body, allowing for detailed imaging of vascular structures. By injecting a contrast agent into the bloodstream, neuroangiography enhances the visibility of blood vessels on imaging studies, enabling healthcare professionals to identify abnormalities such as blockages, aneurysms, and other lesions.

Neuroangiography is particularly valuable in diagnosing cerebral vascular conditions, as it provides clear and detailed images of the arteries and veins. This can be crucial in planning treatments or interventions related to vascular issues, such as endovascular procedures.

In contrast, other imaging modalities like MRI and CT scans are broader in scope and can visualize various tissues, but they are not specialized for vascular imaging to the same extent as neuroangiography. Ultrasound, while useful for certain types of vascular assessments, does not involve contrast agents in the same manner and has limitations regarding the visualization of deeper structures like those found in the brain.
