What is a common diagnostic procedure for detecting arteriovenous malformations?

EEG
MRI
Arteriogram
CT angiography

The correct answer is: Arteriogram

A common diagnostic procedure for detecting arteriovenous malformations (AVMs) is an arteriogram, also known as an angiogram. This procedure involves the injection of a contrast dye into the blood vessels and utilizing X-ray imaging to visualize the vessels in real-time. Because AVMs consist of abnormal connections between arteries and veins, an arteriogram provides detailed information on the blood vessels and the structure of the malformation, allowing for accurate characterization and evaluation. It helps determine the size, location, and associated complications of the AVM, which is essential for planning treatment. While MRI and CT angiography are also valuable imaging techniques for detecting AVMs, arteriograms are particularly advantageous in providing high-resolution images of the vascular structures, making it a preferred method for this specific diagnosis. EEG, on the other hand, is primarily used for assessing electrical activity in the brain and is not relevant to the detection of vascular malformations.
