Prospective Study of High-penetration Super-resolution Transcranial Ultrasound for Early Identification of Postoperative Intracranial Metallic Targets After Aneurysm Clipping
Starting soon
Conditions studied: Intracranial Aneurysms
In brief
To evaluate the patient-level early diagnostic performance of high-penetration super-resolution transcranial ultrasound for identifying intracranial metallic targets, and to further assess clip-level detection, localization, agreement, and its complementary value to routine postoperative imaging.This study does not alter routine clinical treatment. All participants will undergo standardized high-penetration super-resolution transcranial ultrasound within 3 hours after surgery. Postoperative CT is mandatory for all participants; CTA or other routine postoperative imaging will be obtained only when clinically indicated.

Who can join
Age: 18 and older, up to 85. Sex: any. Healthy volunteers: not accepted.
You may qualify if…
- Age 18-85 years;
- Positive group: patients undergoing intracranial aneurysm clipping with implanted metallic clips; negative control group: postoperative craniotomy patients without implanted clips;
- Ability to complete transcranial ultrasound within 3 hours after surgery;
- Availability of postoperative CT;
