Snoeren et al. described a high-resolution 3D X-ray imaging protocol for intracranial nitinol stents with C-arm flat panel detector. Images obtained with stents of various brands are provided. Generally, 2D fluoroscopy only enables the visualization of the stent end-markers. Today 3D imaging of such objects with some extremely small details remain challenging but with such optimized protocols nitinol struts can be well viewed while keeping absorbed dose below recommended values. They are used in order to judge wall apposition and stent conformity in cases of curved vascular anatomy. High-resolution imaging is of major interest to assure good stent deployment particularly when using flow-diverter devices.
