Cerebrovascular (stroke) is defined as a sudden focal neurological deficit, caused by a cerebrovascular disease that lasts more than 24 hours. Cerebrovascular insult is divided into ischemic and hemorrhagic. Ischemic stroke is more common, while about 10% of all strokes manifest as hemorrhagic. Along with cardiac and malignant diseases, cerebrovascular diseases are the most common cause of mortality and disability in modern humans. Every year, about 5.5 million people worldwide suffer from stroke. Due to this fact, this disease is the leading cause of disability. Prevention is the most important strategy in the approach to stroke, it is especially important for risk factors that we can influence in a timely manner, such as: smoking, diet, alcohol, obesity, etc .. In prevention, treatment of diseases such as hypertension, heart disease is important , diabetes, hypercholesterolemia. Diagnosis and determination of stroke type requires neuroimaging with computed tomography. Detailed history and recording usually preclude imitation of a stroke. CT is one of the first diagnostic modalities by which the brain is imaged, to discern the difference between ischemic and hemorrhagic stroke. The objectives of this retrospective analysis in this paper were to estimate the frequency of cerebrovascular insult in patients who underwent CT examination of the brain at the Clinical Department of Radiology at the University Hospital Center Rijeka, in the period from 1. January 2020 to 31. December 2020. During the period, 255 data from a patient's medical records were collected anonymously. In addition to conducting a statistical link between patients with cerebrovascular insult and morphologically normal CT findings or without signs of ischemic stroke, without definite ischemic or hemorrhagic changes and without the presence of tumor mass, this study sought to conclude which group, determined by sex and age more often results in proven radiological finding of CVI and the incidence of CVI according to the type of pathological change of stroke based on the radiological finding.
