AR coregistration capabilities are adequate when revised by other intraoperative guidance devices. When performed with "freeware" software and conventional digital cameras, it is relatively inexpensive, which makes it a potential tool for surgical planning and noncontinuous intraoperative guidance in neurosurgery. Its largest drawbacks are the inability to function in deep-seated lesions and its lack of tracking devices, which gives it a noncontinuous coregistration nature.
Treatment of intracranial ruptured and unruptured aneurysms can be performed with surgical (vascular clips) or endovascular procedures (coils, stents, flow diverters). There are several devices and techniques for endovascular treatment. Knowledge of this techniques allows physicians to choose and interpret accurately imaging modalities for non-invasive follow-up. Through a pictorial essay of imaging follow-up of treated intracranial aneurysms we show the differences in characterization with computed tomography angiography, magnetic resonance angiography without contrast (time of flight or "TOF" technique), contrast enhanced MR angiography (C+) and digital subtraction angiography (DSA). Additionally we recommend imaging modalities for each treatment device.
