Stroke: Introduction and Types01:29

Stroke: Introduction and Types

A stroke is an acute neurological event caused by the sudden disruption of cerebral blood flow, leading to rapid loss of neuronal function. Neurons depend on continuous oxygen and glucose supply, so even brief interruptions can cause irreversible injury within minutes. Strokes are classified into ischemic and hemorrhagic types.Ischemic StrokeIschemic strokes are most common and occur due to arterial occlusion, depriving brain tissue of oxygen and nutrients. This leads to energy failure, ionic...

Imaging Studies II: Ultrasonography

IntroductionUltrasonography, or renal ultrasound, is a noninvasive medical imaging technique that uses high-frequency sound waves to visualize the kidneys, ureters, bladder, and surrounding tissues.Indications for Urinary System UltrasonographyUrinary system ultrasonography is indicated in various clinical scenarios, such as:Kidney Stones (Urolithiasis): To detect and monitor the size and presence of kidney or urinary tract stones.Hydronephrosis: To assess the dilation of the renal pelvis and...
Ultrasonography01:17

Ultrasonography

Ultrasonography is an imaging technique that uses high-frequency sound waves to visualize the body's internal structures. It is a non-invasive and safe procedure that does not involve the use of ionizing radiation, making it widely used in various medical fields. Ultrasonography is used to study heart function, blood flow in the neck or extremities, certain conditions such as gallbladder disease, and fetal growth and development.
During an ultrasonography procedure, a handheld device called a...

Imaging Studies VII: Vascular Imaging

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...

Imaging Studies for Cardiovascular System II:Types of Echocardiography

Echocardiography plays a role in assessing cardiac health and detecting heart conditions, with various types providing critical insights for diagnosis and treatment.
Types of Echocardiography
Transthoracic Echocardiography (TTE)
TTE is the most common type of echocardiogram which involves placing a transducer on the patient's chest, emitting sound waves to create heart images. TTE is invaluable for evaluating the heart's size, structure, and motion, making it particularly useful for diagnosing...

Area of Science:

  • Neonatal neurology
  • Pediatric neuroradiology
  • Cerebrovascular disease

Background:

  • Neonatal stroke diagnosis relies on imaging, but standardized templates are lacking.
  • Adult stroke templates provide a basis, but require adaptation for neonatal physiology.
  • Understanding evolving infarction stages is crucial for accurate assessment.

Purpose of the Study:

  • To develop arterial and venous stroke templates for neonatal brain ultrasound.
  • To adapt adult stroke templates for recognizing patterns in newborns.
  • To aid in the classification and understanding of neonatal cerebrovascular injury.

Main Methods:

  • Utilized adult stroke templates as a foundation.
  • Designed templates reflecting neonatal brain ultrasound imaging.
  • Incorporated stages of infarction: swelling, necrosis, organization, and tissue loss.
  • Developed templates for both arterial and venous stroke patterns.

Main Results:

  • Established templates for arterial stroke, including Circle of Willis and perforator branches.
  • Identified Middle Cerebral Artery (MCA) truncal stroke as a distinct entity.
  • Enabled recognition of combined infarction patterns and watershed injuries.
  • Developed venous stroke templates to understand thrombosis-related brain injury and intracranial hemorrhage.

Conclusions:

  • The developed templates facilitate the recognition of diverse neonatal stroke types using brain ultrasound.
  • These tools aid in differentiating stroke severity and prognosis, including MCA stroke.
  • Venous stroke templates improve understanding of neonatal venous sinus thrombosis and associated hemorrhages.
  • Templates offer a standardized approach to neonatal cerebrovascular disease assessment.
