Summary
Multimodal imaging, including computed tomography (CT) and CT angiography, is crucial for stroke patients. These methods aid in diagnosing arterial blockages and selecting candidates for mechanical thrombectomy.
Area of Science:
- Neurology
- Radiology
- Medical Imaging
Background:
- Stroke management relies on rapid diagnosis and intervention.
- Mechanical thrombectomy has shown efficacy in treating acute ischemic stroke.
- Patient selection for thrombectomy is critical and relies on imaging.
Purpose of the Study:
- To review imaging techniques used in stroke code patients.
- To evaluate the role of different imaging modalities in selecting patients for mechanical thrombectomy.
- To provide evidence-based recommendations for imaging in acute stroke.
Main Methods:
- Analysis of multimodal imaging techniques in stroke patients.
- Review of five recent clinical trials on mechanical thrombectomy.
- Literature synthesis of imaging's role in patient selection.
Main Results:
- Conventional CT with Alberta Stroke Programme Computed Tomography Score (ASPECTS) and CT/MR angiography are essential.
- Perfusion imaging (CT/MR) is beneficial in specific clinical scenarios.
- Imaging protocols varied across recent thrombectomy trials.
Conclusions:
- Conventional CT and angiography are recommended for all stroke patients undergoing evaluation for thrombectomy (Level I, Grade A).
- Perfusion imaging offers adjunctive value in select cases.
- Standardized imaging protocols are needed to optimize stroke care.

Cardiovascular magnetic resonance imaging, or CMRI, is a non-invasive diagnostic test that employs a magnetic field and radiofrequency waves to create precise images of the heart and arteries. It provides comprehensive information about cardiac anatomy, function, perfusion, and tissue characterization without ionizing radiation.IndicationsCMRI diagnoses various heart conditions, including tissue damage from heart attacks, ischemic heart disease, myocarditis, aortic issues (tears, aneurysms,...

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...

Introduction:Magnetic Resonance Imaging, or MRI, can include a specialized imaging technique of the urinary system known as Magnetic Resonance Urography (MRU). This radiation-free technique uses strong magnetic fields and radio waves to produce detailed images with the help of a computer. MRU is particularly effective for visualizing fluid-filled structures like the kidneys, ureters, and bladder.Applications of MRI in the Genitourinary SystemKidneys and Ureters: MRI detects tumors, cysts,...
