影像学技术在颅内动脉瘤介入栓塞术后复查中的应用进展

Application Progress of Imaging Techniques in Re-examination of Intracranial Aneurysm After Interventional Embolization

数字减影血管造影是颅内动脉瘤栓塞术后常用复查手段,但患者耐受性差。随着医学影像技术发展,MRI受金属伪影影响降低,具备无辐射、无创、高分辨率等优势。零回波磁共振血管成像和高分辨率血管壁成像技术具有更好的临床应用价值,既能更好地显示血管的狭窄程度和残留动脉瘤的大小,又可以显示血管壁的强化程度和预后情况。随着能谱CT的发展,CT血管造影在动脉瘤术后复查中的应用价值进一步提升。本文主要阐述不同影像学技术在颅内动脉瘤术后复查中的应用进展。

Digital subtraction angiography examination is a common reexamination method after intracranial aneurysm embolization,but it is poorly tolerated by patients.With the development of medical imaging technology,MRI examination is less affected by metal artifacts and has the advantages of non-radiation,non-invasive and high resolution.Zero echo magnetic resonance angiography and high resolution vessel wall imaging technology will have better clinical application value:it can not only better show the degree of vascular stenosis and the size of residual aneurysm,but also show the degree of vascular wall enhancement and prognosis.With the development of spectral CT,the application value of computed tomography angiography in the postoperative review of aneurysm has been further improved.This article mainly describes the application of different imaging techniques in postoperative reexamination of intracranial aneurysms.
