    Area of Science:

    • Medical Imaging
    • Cardiovascular Research
    • Biomedical Engineering

    Background:

    • Vascular stenosis poses significant health risks.
    • Accurate quantitative assessment of stenosis is crucial for effective treatment.
    • Existing methods for stenosis quantification have limitations.

    Purpose of the Study:

    • To develop and validate a quantitative method for analyzing vascular stenoses.
    • To utilize digital subtraction angiography (DSA) for precise stenosis measurement.
    • To establish a reliable method for assessing the degree of vascular narrowing.

    Main Methods:

    • Experimental studies using vessel phantoms with controlled stenoses.
    • Development of a quantitative analysis method based on DSA.

  • Application of video densitometry to measure relative contrast density.
  • Relating contrast density to the transverse vessel area and stenosis degree.

    • Main Results:

    • A method for quantitative analysis of vascular stenoses using DSA was successfully developed.
    • Digital information from DSA provided quantitative measurements of contrast within vessels.
    • Relative contrast density was found to be proportional to the transverse vessel area.
    • The method provides a quantitative measure of the relative degree of stenosis with a standard deviation not exceeding 7.5%.

    Conclusions:

    • The developed DSA-based method offers accurate and quantitative analysis of vascular stenoses.
    • Video densitometry provides a reliable means to assess stenosis severity.
    • This technique has the potential to improve the clinical evaluation of vascular diseases.
