Abstract:
The authors draw attention to the importance of X-ray examinations in craniocerebral gunshot injuries. A life-saving neurosurgical operation of a victim resulted in changes occurring not only in the soft tissue, but also in the bony structures of the cranium, which practically rendered impossible any assessment of and differentiation between the location of entrance and exit wounds during autopsy. The assessment of preoperative head X-ray demonstrated the presence of characteristic crater-like bone defects, what allowed for determining the location of the entrance and exit wounds. The medico-legal examination of bone defects indicated that the entrance wound was situated on the left side, contrary to information provided by hospital medical records.

Definition and Purpose
An X-ray, or radiograph, is a non-invasive method that uses ionizing radiation to take images of internal structures. It is mainly used in cardiac imaging to examine the heart, lungs, and major blood vessels, aiming to identify abnormalities in the heart's size, shape, and position, such as heart failure, congenital defects, and vascular...
Radiological Investigation I: X-ray and CT
Computed Tomography
The technique was invented in the 1970s and is based on the principle that as X-rays pass through the body, they are absorbed or reflected at different levels. In the technique, a patient lies on a motorized platform while a computerized axial tomography (CAT) scanner rotates...
Types of Radioactivity
Alpha (α) decay is the emission of an α particle from the nucleus. For example, polonium-210 undergoes α decay:
X-ray Diffraction of Biological Samples
According to Bragg's law, when X-rays strike the sample positioned on a stage, the rays are scattered by the electron clouds around the sample atoms. The X-ray diffraction or scattering is caused by constructive interference of the X-ray waves that reflect off the internal crystal...
