Diagnostic Work-Up of a Giant Calcified Intracranial Aneurysm: Comparing 4D-CTA and Cerebral Angiogram Findings
The risks associated with unruptured intracranial aneurysms can be neurologically debilitating and even fatal. Evaluation of these aneurysms is critical for determining what type of intervention is warranted, if at all. Cerebral angiography has long been the gold standard in the evaluation of intracranial aneurysms. However, this diagnostic modality is accompanied by several risks that are made...
متن کاملCerebral Angiographic Findings in Non-Traumatic Intracranial Hemorrhage: A Single Center Experience in the West of Iran
Background and Aim: This study aimed at analyzing the demographic characteristics of the patients with non-traumatic intracranial hemorrhage, their angiographic results and the correlation between computed tomography (CT) scan and angiography findings. Methods and Materials/Patients: In a descriptive study, we retrospectively reviewed the records of the patients with non-traumatic intracranial...
متن کاملCardiac cycle-related volume change in unruptured cerebral aneurysms: a detailed volume quantification study using 4-dimensional CT angiography.
BACKGROUND AND PURPOSE The hemodynamic factors of aneurysms were recently evaluated using computational fluid dynamics in a static vessel model in an effort to understand the mechanisms of initiation and rupture of aneurysms. However, few reports have evaluated the dynamic wall motion of aneurysms due to the cardiac cycle. The objective of this study was to quantify cardiac cycle-related volume...
متن کاملThe Prevalence and Properties of Intracranial Vascular Abnormalities in CT Angiography of Patients with Non-traumatic Intracranial Hemorrhage
Introduction:Intracranial hemorrhage (ICH) is divided into two traumatic and non-traumatic categories. The present study sought to investigate the anatomical properties of non-traumatic intracranial hemorrhage in Kerman, Iran. Method:A total of 305 non-traumatic ICH cases were chosen in Shafa medical center. Data from patients’ files and CT scan images, including demographic factors and type o...
متن کاملExploring the age of intracranial aneurysms using carbon birth dating: preliminary results.
BACKGROUND AND PURPOSE There is a controversy about the time span over which cerebral aneurysms develop. In particular, it is unknown whether collagen in ruptured aneurysms undergoes more rapid turnover than in unruptured aneurysms.(14)C birth dating of collagen could be used to address this question. METHODS Aneurysmal domes from patients undergoing surgical treatment for ruptured or unruptu...
