Imaging Studies for Cardiovascular System VI: Calcium -Scoring CT

222
Calcium-Scoring CT ScanA calcium-scoring CT scan, also known as coronary artery calcium (CAC) scan, detects calcium deposits in the coronary arteries. This test assesses the risk of coronary artery disease (CAD), which can lead to cardiovascular events such as angina, heart failure, and sudden cardiac arrest.A calcium-scoring CT scan is generally recommended for individuals at intermediate risk of CAD without symptoms. It includes:Men aged 40-75 and women aged 50-75: Especially those with a...

Atherosclerosis II: Clinical Manifestations and Diagnostic Tests

188
Atherosclerosis is a progressive disorder that leads to the thickening and narrowing of arterial walls due to plaque buildup. This condition can cause various symptoms depending on the arteries affected:Coronary Artery Disease (CAD): This condition affects the coronary arteries and may lead to chest pain (angina), shortness of breath (dyspnea), heart attacks, and other heart disease symptoms.Cerebrovascular Disease: This affects blood flow to the brain, causing transient ischemic attacks (TIAs)...

Area of Science:

  • Medical Imaging
  • Biomedical Engineering
  • Cardiovascular Research

Background:

  • Magnetic resonance imaging (MRI) is crucial for atherosclerosis risk assessment, classifying carotid plaques.
  • MRI provides insights into plaque size, composition, and vessel lumen beyond simple stenosis.
  • Commercial software for carotid artery stenosis assessment is costly and inaccessible to many.

Purpose of the Study:

  • To develop a cost-free software system for carotid artery plaque analysis.
  • To enable registration, marking, and 3D visualization of the carotid artery wall and lumen.
  • To create a streamlined, open-source tool for enhanced atherosclerosis risk assessment.

Main Methods:

  • Development of a software system using open-source tools and libraries.
  • Modification and significant improvement of the QDCM library's image loading and display module.
  • Implementation of a Bezier function for polygon smoothing and 3D visualization.

Main Results:

  • Achieved a >10,000% improvement in the image loading and display module.
  • Enabled smoother 3D visualization of the carotid lumen and wall through curve interpolation.
  • Created a functional, streamlined software for carotid plaque analysis.

Conclusions:

  • The developed open-source software offers an accessible alternative for carotid artery stenosis assessment.
  • The software facilitates improved 3D visualization and risk stratification of carotid plaques.
  • This tool can aid practitioners in evaluating atherosclerosis risk without high costs.
