Summary
Neuroimaging is crucial for diagnosing acute stroke, guiding treatment, and predicting outcomes by evaluating brain tissue and blood vessels. It helps identify infarcts, bleeding, and assess blood flow in stroke patients.
Area of Science:
- Neurology
- Radiology
- Medical Imaging
Background:
- Acute stroke results from disrupted blood flow or bleeding in the central nervous system.
- Accurate diagnosis and timely intervention are critical for patient outcomes.
- Neuroimaging plays a pivotal role in the management of acute stroke.
Purpose of the Study:
- To outline the role of neuroimaging in the evaluation of patients with acute stroke.
- To describe how imaging features inform diagnosis, treatment decisions, and prognosis.
Main Methods:
- Review of neuroimaging techniques applied in acute stroke.
- Delineation of key imaging findings in the brain parenchyma and vasculature.
Main Results:
- Imaging identifies early ischemic changes, established infarcts, and penumbra (tissue at risk).
- Neuroimaging detects hemorrhage, arterial/venous steno-occlusive disease, and vascular malformations.
- Vessel imaging assesses collateral flow in cases of vessel occlusion.
Conclusions:
- Neuroimaging is indispensable for the comprehensive assessment of acute stroke.
- Imaging findings guide acute treatment strategies and prognostic evaluations.
- Understanding imaging characteristics is key for effective stroke management.

Brain imaging technologies provide critical insights into both the structure and function of the human brain, enabling medical professionals and researchers to diagnose, study, and treat neurological disorders or psychiatric disorders more effectively.
These technologies include computerized axial tomography (CAT or CT scans), positron-emission tomography (PET scans), magnetic resonance imaging (MRI), functional magnetic resonance imaging (fMRI), and Transcranial Magnetic...

DefinitionRenal angiography, also known as renal arteriography, is an imaging technique used to obtain a comprehensive view of blood flow and the vascular structure of blood vessels in the kidneys and surrounding areas.PurposeRenal angiography detects blood vessel abnormalities in the kidneys, such as aneurysms, stenosis, thrombosis, vascular tumors, and renal artery stenosis. It evaluates kidney function and guides interventional treatments like angioplasty or stent placement.Pre-Procedure...
