Imaging Studies for Cardiovascular System V: CT01:28

Imaging Studies for Cardiovascular System V: CT

131
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

202
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:

  • Cardiovascular Imaging
  • Medical Physics
  • Radiology

Background:

  • Coronary CT angiography (CTCA) is crucial for diagnosing coronary artery disease.
  • Motion artifacts, especially at high heart rates (>70 bpm), hinder CTCA interpretation and quantification.
  • Existing methods require improved motion correction for enhanced diagnostic accuracy.

Purpose of the Study:

  • To introduce a novel quantitative method for assessing motion degradation in CTCA.
  • To evaluate the effectiveness of the second-generation GE SnapShot Freeze software (SSF-2.0) in reducing motion artifacts.
  • To validate the software's performance using both objective and subjective measures.

Main Methods:

  • Analysis of 196 coronary segments with motion artifacts from 49 patients undergoing CTCA at heart rates >70 bpm.
  • Objective quantification of motion degradation using cross-section eccentricity before and after SSF-2.0 processing.
  • Subjective assessment of vessel clarity by an expert cardiothoracic radiologist before and after SSF-2.0 application.

Main Results:

  • A statistically significant decrease in vessel eccentricity (P < 0.001) was observed after SSF-2.0 processing.
  • A significant improvement in subjective vessel clarity (P < 0.001) correlated with SSF-2.0 application.
  • The quantitative method demonstrated a strong correlation with the software's motion reduction capabilities.

Conclusions:

  • The developed quantitative method effectively evaluates CTCA motion artifacts.
  • SSF-2.0 motion-correction software significantly reduces motion degradation in CTCA.
  • Both the novel evaluation technique and SSF-2.0 show potential for improving clinical CTCA interpretation.
