Nontraumatic Intracranial Hemorrhage
Nontraumatic (or spontaneous) intracranial hemorrhage most commonly involves the brain parenchyma and subarachnoid space. This entity accounts for at least 10% of strokes and is a leading cause of death…
NEUROLOGICAL IMAGING
Spine and Spinal Cord Emergencies: Vascular and Infectious Causes
This content presents infectious and vascular spinal emergencies, including epidural abscess, nontraumatic epidural hematoma, vascular malformations, and spinal cord infarction. The spine is subjected to multiple potential insults, such as…
Diffusion MR Imaging: An Important Tool in the Assessment of Brain Tumors
For over 20 years, conventional MR imaging has been used for assessing brain tumors. However, conventional MR imaging tends to underestimate the extent of the tumor, perhaps leading to suboptimal…
Head Trauma
Worldwide, an estimated 10 million people are affected annually by traumatic brain injury (TBI). More than 5 million Americans currently live with long-term disability as a result of TBI and…
Seizures: Emergency Neuroimaging
The various findings observed on computed tomography (CT) and magnetic resonance (MR) imaging examinations in patients with seizures reflect the variety of different causes that give rise to this common…
Acute Neurointerventional Therapies
In the past two decades, minimally invasive neurointerventional therapies have become the standard of care for a variety of neurologic diseases. This article reviews some of the principal areas in…
Intracranial Hypotension and Intracranial Hypertension
Intracranial pressure (ICP) is the pressure within the intracranial space. Intracranial hypotension is a clinical syndrome in which low cerebrospinal fluid volume (CSF) results in orthostatic headache. Severe cases can…
Maxillofacial (Midface) Fractures
Recognizing typical midface fracture injuries and describing the imaging findings that are relevant to the maxillofacial surgeon are important. Particular attention should be paid to findings that potentially result in…
Orbital and Intracranial Complications of Acute Sinusitis
This article addresses the imaging considerations for subtle early studies of imaging findings in sinusitis, focusing on early detection by the radiologist, which depend on dedicated imaging protocols and a…
Imaging of Acute Ischemic Stroke
In this article the individual components of multimodal computed tomography and multimodal magnetic resonance imaging are discussed, the current status of neuroimaging for the evaluation of the acute ischemic stroke…
