The most effective diagnostic tool for diagnosing clogged neck arteries is cerebral angiography, also known as carotid angiogram, states WebMD.

This allows the doctor to see narrowing or blockages on a live X-ray screen.

Carotid arteries are blood vessels that pass from the aorta to the brain through the neck, according to VascularWeb. These arteries provide oxygen-rich blood to the brain. Clogged carotid arteries can cause serious medical problems if untreated. Carotid artery disease is a serious condition that can lead to life-threatening complications such as stroke and transient ischemic attack. It is important to consult a physician with any questions about clogged carotid arteries or any other medical condition.
