Prospective Study of High-penetration Super-resolution Transcranial Ultrasound for Early Identification of Postoperative Intracranial Metallic Targets After Aneurysm Clipping

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.
