Is it possible to locate cholesterol clogs in specific arteries?

Hypothetically: You go into some kind of scanner and a 3D model mapping all of your arteries shows up on the computer. The scan also picks up on any stagnant cholesterol. So a doctor can visually see if there are any severely clogged arteries.

^ That was a very arbitrary example. But you get my point...

Is there a test out there that can detect atherosclerosis in a specific location in the body? Maybe even measure the amount of cholesterol / the severity of blood flow restriction in that specific artery?

If it does exist, do we have some kind of procedure that can definitively correct the problem using this information?

Hereâs another hypothetical example: You have a severe blockage in your common carotid artery and stroke is almost immanent. Since we know exactly where the problem is, surgeons rip the artery open and take out the fatty substance.

*If there is no way to locate the specific sites of clogs, wouldnât ^^^ be a plausible cure for stroke and heart attacks if we DID have the technology? Itâs crude, but they already do surgery on major arteries like they aorta. They already know how to stop hearts and shit. Iâm pretty sure they could do this.*

Answer
Yes. The first video is how to find arterial blockage, the second video is how to correct arterial blockage and the third link is how to help avoid both these procedures. :)

Answer
here some x-rays you can use to show how food enters and exits the body from swallowing to pooing, the images are taken by getting the patient to swallow a powdered based drink called barium. barium is a dense material which allows doctors to investigate whether your insides are working properly.

swallowing (food entering mouth, going down oesophagus into stomach):

here is a youtube video of a barium swallow in real time, this person has somesort of oesophagile reflux - this were food travels back up toward the mouth instead of going into stomach.

this is the stomach, the arrow points to were the oesophagus meets the stomach:

This one is called a small bowel enema, a tube (which you can see on the x-ray) is inserted down the oesophagus into the small bowel. this is were food goes after the stomach.

This one is called a barium enema, this image is of the large bowel, this is were food goes after the small bowel... after this, its time for your food to meet the toliet

http://www.youtube.com/watch?v=BF_1sUYHL5M - the colon (large bowel)

heres another one

http://www.youtube.com/watch?v=8BVY5qfZKwk&feature=related - again 3d colon taken using a CT scanner, a ct scanner is a hi-tech x-ray mechine which rotates around the body also called cat scan.

if you talk about the structures of each segment/body piece, you might be able to distinguish them on the x-rays

bored now so hope this is ok etc...
