Quantified analysis of a carotid angiogram

Area of Science:

• Neuroradiology
• Medical Imaging Analysis
• Biomedical Engineering

Background:

• Standardized analysis of carotid angiograms is challenging due to anatomical variations and magnification differences.
• Accurate mapping of supratentorial structures is crucial for diagnosing neurological conditions.

Purpose of the Study:

• To develop an objective and efficient method for analyzing lateral skull angiograms.
• To compensate for anatomical and magnification variations in angiographic imaging.

Main Methods:

• Utilizing a hand-held programmable calculator to remodel the lateral skull view profile.
• Employing statistical analysis on 85 normalized carotid angiograms.
• Generating a numbered map of supratentorial structures.

Main Results:

• The developed method successfully remodels skull profiles to fit reference outlines.
• A numbered map of supratentorial structures was created from statistical analysis.
• Objective angiogram analysis is achievable within 20 minutes.

Conclusions:

• The programmable calculator method offers a rapid, objective, and accessible approach to carotid angiogram analysis.
• This technique reduces the need for sophisticated equipment in neuroradiological assessments.
• The method provides a reliable tool for evaluating supratentorial structures.
