U.S., Aug. 19 -- ClinicalTrials.gov registry received information related to the study (NCT07769814) titled 'Photon-counting CT for Intracranial Stent Assessment' on Aug. 08.
Brief Summary: Intracranial atherosclerotic disease is an important cause of ischemic stroke, and intracranial stent implantation is increasingly used for patients with severe stenotic lesions. Evaluation of stent patency and detection of in-stent restenosis are essential during follow-up. Digital subtraction angiography (DSA) remains the reference standard for intracranial stent assessment; however, it is an invasive procedure associated with potential complications and radiation exposure. Conventional CT angiography may be limited by stent-related artifacts, includi...
