光子计数CT在头颈血管成像中的应用进展
Advances in the application of photon-counting CT in head and neck vascular imaging
摘要
Abstract
Head and neck CT angiography(CTA)is currently the first-line non-invasive imaging modality for diagnosing cerebrovascular diseases.Compared with conventional CT,photon-counting CT(PCCT)provides higher spatial and spectral resolution,enhanced multi-material decomposition capability,and a lower radiation dose,showing promising potential for head and neck vascular imaging.This review briefly describes the imaging principles and core technical advantages of PCCT,summarizes current strategies for optimizing acquisition and reconstruction parameters for PCCT-based head and neck CTA,and reviews advances in its clinical applications for visualizing small head and neck vessels,identifying high-risk plaques in the head and neck arteries,assessing intracranial aneurysms before and after treatment,and performing follow-up after head and neck vascular stent placement.关键词
