Imaging Studies for Cardiovascular System V: CT

108
Cardiac computed tomography (CT) scanning is an advanced cardiac imaging technique that utilizes CT technology, with or without intravenous (IV) contrast, to produce accurate cross-sectional virtual slices of specific areas of the heart, coronary circulation, and major blood vessels such as the aorta, pulmonary veins, and arteries. The computer processes these slices to generate three-dimensional images. Multidetector CT (MDCT) is a rapid form of CT scanning that captures multiple slices...

Computed Tomography

Tomography refers to imaging by sections. Computed tomography (CT) is a non-invasive imaging technique that uses computers to analyze several cross-sectional X-rays to reveal minute details about structures in the body.
The technique was invented in the 1970s and is based on the principle that as X-rays pass through the body, they are absorbed or reflected at different levels. In the technique, a patient lies on a motorized platform while a computerized axial tomography (CAT) scanner rotates...

Imaging Studies for Cardiovascular System VI: Calcium -Scoring CT

178
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...

Area of Science:

  • Medical imaging
  • Biomedical engineering
  • Radiology

Background:

  • Coronary CT angiography (CCTA) is crucial for atherosclerosis detection.
  • Cardiac implants like pacemakers and defibrillators cause metal artifacts in CCTA, hindering plaque visualization.
  • Existing metal artifact reduction methods are insufficient for visualizing plaque near implant components.

Purpose of the Study:

  • To develop and evaluate a novel reconstruction method (STF-dKCR) for reducing metal artifacts in CCTA.
  • To improve the visualization of coronary artery plaque in patients with cardiac implants.
  • To specifically enhance the imaging of plaque located near pacemaker or defibrillator leads.

Main Methods:

  • The STF-dKCR method incorporates a deformable model for metal leads, including novel parameterization and 3D-2D preregistration.
  • A polyenergetic forward model estimates x-ray propagation and spectral properties through the metal component.
  • The method was validated using physical data from a cardiac phantom with a simulated vessel, metal wire, and Teflon sphere, compared against Filtered Back Projection (FBP) and FBP with metal artifact reduction (FBP-MAR).

Main Results:

  • STF-dKCR significantly reduced metal artifacts compared to FBP and FBP-MAR.
  • Only STF-dKCR substantially improved the visibility of a simulated plaque (Teflon sphere) near the metal wire.
  • The attenuation of the Teflon bead improved with STF-dKCR, closely matching the expected value, unlike FBP and FBP-MAR.

Conclusions:

  • The proposed STF-dKCR reconstruction method effectively reduces metal artifacts in CCTA.
  • This technique shows significant potential for improving plaque visualization in the challenging clinical scenario of patients with cardiac implants.
  • STF-dKCR offers a promising solution for enhanced atherosclerosis detection in the presence of wire-shaped metal components.
