“…SAH appears as a hypointense area surrounded by hyperintense subarachnoid spaces on the GRE MRI pulse sequence [19,31,32]. The newer 3-dimensional CT angiography (CTA) and MR angiography (MRA) can facilitate the detection of very small aneurysms and are a good noninvasive alternative to digital subtraction angiography as a screening tool as well during the follow up after initial detection [33][34][35]. …”

Summary: Intracranial hemorrhage is the third most common cause of stroke and involves the accumulation of blood within brain parenchyma or the surrounding meningeal spaces. Accurate identification of acute hemorrhage and correct characterization of the underlying pathology, such as tumor, vascular malformation, or infarction, is a critical step in planning appropriate therapy. Neuroimaging studies are required not only for diagnosis, but they also provide important information on the type of hemorrhage, etiology, and the pathophysiological process. Historically, computed tomography (CT) scan has been the diagnostic imaging study of choice; however, there is growing evidence suggesting that magnetic resonance imaging (MRI) is at least as sensitive as CT to detect intraparenchymal hemorrhages in the hyperacute setting, and actually superior to CT in the subacute and chronic settings. Unique MRI and CT characteristics differentiate secondary causes of hemorrhage from the more common hypertensive hemorrhage. Baseline and serial studies can be used to identify patients who might benefit from acute interventions. In addition, new imaging modalities, (such as magnetic resonance spectroscopy, diffusion tensor imaging, and 320-row CT) are promising research techniques that have the potential to enhance our understanding of the tissue injury and recovery after intracranial hemorrhages.

“…2,3,[32][33][34] Because DSA and 3DRA do not necessarily include all vascular territories, analysis of results was performed per predefined anatomic aneurysm location and not per detected aneurysm. To minimize verification bias, we also included patients with no aneurysms found on DSA and CTA.…”

“…Among aneurysms detected on CTA and then undergoing surgery, 100% correlation was observed between CTA and catheter angiography [26]. CTA, as a less invasive alternative to cerebral angiography, is a widely accepted method for detection and characterization of cerebral aneurysms when planning surgical intervention [27].…”
