Imaging Studies for Cardiovascular System VI: Calcium -Scoring CT

19
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

11
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)...

Atherosclerosis I: Introduction01:30

Atherosclerosis I: Introduction

9
Atherosclerosis is a progressive disorder characterized by the buildup of plaques on the arterial inner wall, causing them to narrow and harden over time. These plaques comprise lipids, calcium, blood components, carbohydrates, and fibrous tissue. The process primarily affects the intima of large and medium-sized arteries, reducing blood flow in any artery.Etiology and risk factorsThe cause of atherosclerosis is multifactorial, involving a complex interplay among endothelial injury, lipid...

Coronary Artery Disease I: Introduction

17
Coronary Artery Disease (CAD): An Overview with Scientific InsightsCoronary Artery Disease (CAD), often referred to as C-A-D, is a prevalent blood vessel disorder classified under the broader category of atherosclerosis. Atherosclerosis is a pathological process characterized by the hardening and narrowing of arteries due to the accumulation of atherosclerotic plaques. These plaques are composed of cholesterol, fatty substances, inflammatory cells, calcium, and fibrin, reducing blood flow to...

Atherosclerosis IV: Nursing Management

18
Nursing management for a patient with arteriosclerosis involves a comprehensive approach focusing on lifestyle modification, disease monitoring, education, and symptomatic care. Here is an overview of effective nursing strategies:Assessment and Monitoring: Initial and ongoing assessments are crucial. Nurses must document the patient's medical history, including any hypertension, diabetes, hyperlipidemia, and other cardiovascular diseases. Assessments also cover family history and lifestyle...

Imaging Studies for Cardiovascular System V: CT

22
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...

Area of Science:

  • Vascular Medicine
  • Radiology
  • Neurology

Background:

  • Carotid artery atherosclerosis is a significant risk factor for ischemic stroke.
  • Current reporting of carotid plaque features lacks consensus, hindering consistent interpretation.
  • Vulnerable plaque morphology is recognized but not uniformly reported.

Purpose of the Study:

  • To introduce the Plaque-RADS (Reporting and Data System) score for standardized carotid plaque imaging and reporting.
  • To establish a consistent and comprehensive approach for evaluating carotid plaque characteristics.
  • To develop a universal classification system for carotid plaque and its defining features.

Main Methods:

  • A panel of experts developed the Plaque-RADS categories through consensus.
  • Multimodality imaging analysis was employed to define plaque characteristics.
  • Existing published reports informed the development of the classification system.

Main Results:

  • The Plaque-RADS score provides a morphological assessment alongside stenosis quantification.
  • The score ranges from grade 1 (no plaque) to grade 4 (complicated plaque).
  • Visual examples are provided to clarify Plaque-RADS categories for researchers and clinicians.

Conclusions:

  • Plaque-RADS offers a standardized and reliable method for reporting carotid plaque using various imaging modalities (ultrasound, CT, MRI).
  • This scoring system can improve patient care by identifying individuals who may benefit from specific medical interventions.
  • Structured reporting and a standardized lexicon enhance communication among healthcare professionals and researchers.
