Standards in neurosonology. Part I

Area of Science:

• Neurology
• Medical Imaging
• Vascular Ultrasound

Background:

• Standardization in medical imaging is crucial for consistent diagnostic interpretation.
• Current ultrasound imaging protocols for cerebral vasculature lack uniformity.
• Specific brain structures like substantia nigra hyperechogenicity require standardized assessment methods.

Purpose of the Study:

• To standardize the performance and description of ultrasound imaging for extracranial and intracranial cerebral arteries.
• To establish criteria for assessing substantia nigra hyperechogenicity using ultrasound.
• To provide practical diagnostic criteria for various cerebrovascular pathologies.

Main Methods:

• Development of comprehensive standards covering equipment, patient preparation, technique, and documentation.
• Inclusion of Duplex and Doppler ultrasound methods in Part I.
• Detailed standards for specific clinical scenarios in Parts II and III.

Main Results:

• Defined standards for ultrasound performance, documentation, and description.
• Presented practical diagnostic criteria for pathologies like vasospasm and stroke monitoring.
• Included guidelines for assessing cerebral circulation arrest and circle of Willis efficiency.

Conclusions:

• The proposed standards aim to enhance the reliability and reproducibility of cerebral ultrasound examinations.
• Implementation of these guidelines will facilitate more accurate diagnosis and management of cerebrovascular diseases.
• Standardized ultrasound assessment of substantia nigra hyperechogenicity is introduced.
