低剂量双源CT头颈主动脉联合扫描的可行 性及在A型主动脉夹层的临床应用价值
Clinical Application of Low-Dose Dual-Source of Cerebral and Carotid Arteries During Aortic CT Angiography in Type A Aortic Dissection
摘要
Abstract
Objective To evaluate the low-dose dual-source head, neck and aorta CT angiography (CTA) in assessing the arteries of type A aortic dissection (ATAAD).Methods Low-dose head, neck and CTA were performed in 133 consecutive patients with suspected ATAAD. The volume CT dose index (CTDIvol) and dose-length product (DLP) were obtained for all scans. Subjective image quality of intracranial, cervical, thoracic and abdominal arteries were assessed. In addition, the surgery related CTA features as well as the Willis circle variations were recorded and analyzed.Results One hundred and twenty-three patients with definite diagnosis of ATAAD were enrolled in this study. Mean CTDIvol and DLP for all patients were (3.4±0.3) mGy and (314.1±29.3) mGy·cm. The detection rates of interlayer tearing involved in cervical artery (n=58), decreased lateral carotid artery density (n=10), carotid atherosclerotic plaque (n=15), dysplasia of vertebral artery (n=12), left vertebral artery with autonomic arterial arch (n=4), right vagus subclavian artery (n=3), intracranial arterial stenosis (n=19) and intracranial aneurysm (n=7) were 47.2%, 8.1%, 12.2%, 9.8%, 3.3%, 2.4%, 15.5% and 5.7% respectively. The Willis circle anatomic variation was found in 57 (46.3%) patients.Conclusion A combined CTA of head, neck and aorta in ATAAD is feasible. The incremental craniocervical information may lead to improved clinical outcomes.关键词
