I Had A Right Supraclinoid ICA Blister Aneurysm That Ruptured

I had a right supraclinoid ICA blister aneurysm that ruptured 6 months ago. The doctor installed a flow diverting stent and it was successful. This happened 6 moths ago. Can you please advise with the test/method to find if there is plaque build up or if there is any leakage. I feel very normal and I am stable and able to do everything I used to do before. Thank you
