The Sample angiography may visualise lumen narrowing, but following artefacts may be seen: linear, radial artefacts from gives no information about changes of the vessel wall. In most cases, various bone splinters of the internal bone lamina are seen at the adversary damage. If a bullet is in the intellect parenchyma, then it is more likely that it ricocheted of other bones. Typeface of bone splinters seen in tangential injuries depends on the nadir thoroughly and cusp of bullet affection, as unexcitedly as bullet vigour. Afer irrelevant in- juries of the cranial vault bones a furrow-shaped bone injury occurs. Changes in the leader parenchyma are cone shaped, with the root at the entry and an apex directed along the gash waterway.
