Summary
The hyperdense artery sign is the earliest computed tomography finding in acute ischemic stroke. This review covers its pathology, incidence, and clinical significance in stroke diagnosis.
Area of Science:
- Neurology
- Radiology
- Medical Imaging
Background:
- Computed tomography (CT) remains the primary imaging modality for acute stroke patients.
- Magnetic resonance imaging (MRI) is increasingly available but not universally the first choice.
- Early detection of ischemic stroke is crucial for timely intervention.
Purpose of the Study:
- To review the pathology, incidence, clinical aspects, and imaging findings of the hyperdense artery sign.
- To discuss the significance of the hyperdense artery sign in acute ischemic stroke.
- To identify future research questions regarding this early stroke marker.
Main Methods:
- Literature review of studies on the hyperdense artery sign in acute ischemic stroke.
- Analysis of imaging findings on computed tomography.
- Discussion of clinical implications and diagnostic value.
Main Results:
- The hyperdense artery sign is the earliest CT marker of acute ischemic stroke.
- Its presence indicates a higher likelihood of early ischemic changes.
- Understanding this sign aids in rapid stroke diagnosis and management.
Conclusions:
- The hyperdense artery sign is a critical finding on CT for diagnosing acute ischemic stroke.
- Further research is needed to fully elucidate its prognostic and therapeutic implications.
- Radiologists and clinicians should be proficient in identifying and interpreting this sign.

01:26Transient Ischemic Attack l: Introduction
A transient ischemic attack (TIA) is a brief episode of neurological dysfunction caused by a temporary, focal reduction in cerebral blood flow. Although symptoms resemble those of an ischemic stroke, the interruption in perfusion is short-lived and does not cause permanent infarction. TIAs are clinically important because they often serve as early warning events for future stroke.Mechanisms of Transient Cerebral IschemiaTransient cerebral ischemia may arise through several mechanisms. One...
01:15Ischemic Stroke l: Introduction
Ischemic stroke is an acute cerebrovascular condition in which blood flow to a brain region is suddenly interrupted, leading to tissue infarction. Neurons depend on continuous oxygen and glucose supply, so even brief reductions in perfusion cause energy failure, ionic imbalance, and irreversible injury. Ischemic strokes are classified into thrombotic and embolic types based on their underlying mechanisms.Thrombotic MechanismsThrombotic stroke develops when a clot forms within a cerebral artery.
01:15Ischemic Stroke ll: Pathophysiology
An ischemic stroke occurs when a cerebral blood vessel becomes obstructed, most often by a thrombus or embolus, interrupting the delivery of oxygen and glucose to brain tissue. Because neurons rely on continuous aerobic metabolism, energy failure begins within minutes of reduced perfusion. The region receiving the least blood flow becomes the infarct core, an area of irreversible cellular death. Surrounding this core lies the penumbra, a zone of hypoperfused but still viable tissue that is...
01:17Hemorrhagic Stroke l: Introduction
A hemorrhagic stroke is an acute neurological event that occurs when a weakened cerebral blood vessel ruptures, allowing blood to accumulate within or around the brain. The sudden release of blood forms a focal hematoma that increases intracranial pressure, displaces neural tissue, and can obstruct cerebrospinal fluid pathways. These effects may be compounded by intraventricular extension of the hemorrhage, cerebral edema, or compression of adjacent structures, all of which contribute to...
01:29Hemorrhagic Stroke ll: Pathophysiology
A hemorrhagic stroke develops when a cerebral blood vessel ruptures, allowing blood to escape into the surrounding brain tissue, as in intracerebral hemorrhage (ICH), or into the subarachnoid space, as in subarachnoid hemorrhage (SAH). Because the skull is a rigid compartment, the sudden presence of extravascular blood rapidly increases intracranial pressure and compresses adjacent neural structures, leading to immediate tissue injury and impaired cerebral perfusion.Mass Effect and Primary...
01:25Imaging Studies for Cardiovascular System VI: Calcium -Scoring CT
Calcium-Scoring CT ScanA calcium-scoring CT scan, also known as coronary artery calcium (CAC) scan, detects calcium deposits in the coronary arteries. This test assesses the risk of coronary artery disease (CAD), which can lead to cardiovascular events such as angina, heart failure, and sudden cardiac arrest.A calcium-scoring CT scan is generally recommended for individuals at intermediate risk of CAD without symptoms. It includes:Men aged 40-75 and women aged 50-75: Especially those with a...
