Background: DynaCT (Angiographic CT) is a new imaging technique that with the use of the angiographic apparatus allows the researchers to obtain images of the human body comparable to standard CTs. Owing to this, only one procedure gives us the possibility to evaluate the vascular system together with the surrounding soft tissues Material/Methods: DynaCT, similarly to the 3D DSA method, involves the use of a C-arm rotating around the patient during the acquisition process. Like in CT, the acquired data may be processed into secondary reconstructions: multiplanar (MPR), maximum-intensity projections (MIP) and volume rendering (VR). Results: Neuroradiologically obtained images allow for an assessment of such brain structures as: ventricular system, subarachnoid cisternae and, to a lesser degree, brain tissue. In case of examinations with intra-arterial contrast administration we get precise images of the vascular system together with cranial bone structures and soft tissues, comparable (from the qualitative point of view) to those obtained during the angioCTs using multi-slice scanners. In case of angioplasty, DynaCT with contrast administration provides us with information on the exact location of a stent inside a vessel. Similarly, in patients with aneurysms embolised with stents, this technique enables the visualization of the stent position in relation to the neck of the aneurysm. Owing to DynaCT, it is possible to quickly evaluate the complications which may appear during endovascular procedures, especially the intracranial bleeding. Conclusions: DynaCT provides us with information that facilitates the process of qualification for the surgical or intravascular treatment. It also allows for a fast evaluation of possible complications which may appear during endovascular procedures, without wasting time for patient's transfer to the CT room.
