Imaging Studies for Cardiovascular System VI: Calcium -Scoring CT

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...

Imaging Studies for Cardiovascular System V: CT

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...

Imaging Studies for Cardiovascular System IV: CMRI

Cardiovascular magnetic resonance imaging, or CMRI, is a non-invasive diagnostic test that employs a magnetic field and radiofrequency waves to create precise images of the heart and arteries. It provides comprehensive information about cardiac anatomy, function, perfusion, and tissue characterization without ionizing radiation.IndicationsCMRI diagnoses various heart conditions, including tissue damage from heart attacks, ischemic heart disease, myocarditis, aortic issues (tears, aneurysms,...

Area of Science:

  • Radiology
  • Medical Imaging
  • Cardiovascular Disease

Background:

  • Carotid artery plaque characterization is crucial for stroke risk assessment.
  • Hounsfield unit (HU) values are used to classify plaque types on CT scans.
  • Multi-energy CT (MECT) offers advanced plaque analysis capabilities.

Purpose of the Study:

  • To analyze carotid artery plaque characteristics using MECT.
  • To investigate the impact of varying energy levels on plaque HU values.

Main Methods:

  • Retrospective analysis of 64 carotid arteries from 32 patients using MECT.
  • Contrast-enhanced imaging with a standardized protocol.
  • Quantification of plaque HU values at monoenergetic levels of 66, 70, 77, and 86 keV.

Main Results:

  • Significant differences in plaque HU values were observed across different keV levels (P=.0001).
  • Increasing keV values led to a statistically significant reduction in plaque HU values.
  • Exclusion of 11 arteries due to absence or heavy calcification of plaque.

Conclusions:

  • Carotid artery plaque HU values are energy-dependent.
  • Plaque classification based on HU values requires consideration of the applied kiloelectron volt (keV) level.
  • MECT provides a more nuanced approach to plaque characterization.
