Photon-counting CT versus regular CT for evaluating carotid artery narrowing before stenting
Part of Brain & nervous system, Heart & circulation clinical trials.
This study compares two types of CT scans to evaluate the arteries in your neck before you have a stent placed. The newer photon-counting CT may provide more detailed images, which could help your doctor plan the procedure more precisely.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You must be 18 years or older.
- You must have narrowing of the carotid artery or plaque in the carotid artery.
- You must be scheduled to have a stent placed in the carotid artery.
- You must be able to understand and sign a consent form.
- You must not be allergic to iodine-based contrast dye.
- You must not have severe kidney disease or other conditions that prevent a contrast CT scan.
- You must not be pregnant or suspect pregnancy.

This study looks at an approach to better plan treatment for people with significant narrowing of the carotid artery (the main artery to the brain). It may help doctors choose safer, more effective care after surgery.
This study tests how well a special PET-MR scan can help evaluate carotid artery plaque in people who have significant narrowing but no symptoms. It may help researchers better understand disease activity to guide treatment decisions like medication alone or medication plus surgery.
This study tests a new way to measure pressure inside the carotid artery during a standard procedure to place a stent (a small mesh tube) to open a narrowed artery. The goal is to see if this pressure measurement can help doctors make better decisions during the procedure and possibly improve outcomes for people with carotid stenosis.
This study tests a new type of CT scan that takes very detailed pictures of the heart and stents. It may help doctors see whether stents remain open and guide future care.
This study looks at whether a new type of CT scanner can take clearer pictures of stents in the brain. The goal is to help doctors see if the stent is working well after it's been placed.
This study uses a special CT scan to look at the inside of your heart arteries and find any high-risk fatty deposits (plaque) that might cause problems later. It aims to see if this scan can predict future heart events, so you and your doctor can make better treatment choices.
