Imaging Studies for Cardiovascular System V: CT01:28

Imaging Studies for Cardiovascular System V: CT

483
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...

Acute Coronary Syndrome III: Diagnostic Studies

357
Diagnosing acute coronary syndrome or ACS begins with a thorough patient history. Notable symptoms include central, crushing chest pain radiating to the left arm, neck, jaw, or back, along with shortness of breath, sweating (diaphoresis), nausea, vomiting, dizziness, and palpitations.It is crucial to note any history of cardiac illnesses and assess risk factors, including age, gender, smoking, hypertension, diabetes, hyperlipidemia, and a sedentary lifestyle.During physical examination, vital...

Imaging Studies for Cardiovascular System VI: Calcium -Scoring CT

679
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...

Coronary Artery Disease II: Pathophysiology

860
Coronary Artery Disease (CAD) originates from a series of events that impair the function of coronary arteries, the blood vessels responsible for delivering oxygen-rich blood to the heart muscle. The pathophysiology of CAD is closely linked to atherosclerosis, a chronic inflammatory and lipid-driven condition affecting the vascular endothelium.1. Endothelial DamageThe process begins with damage to the vascular endothelium, which serves as a protective barrier between the blood and the vessel...

Area of Science:

  • Forensic Radiology
  • Cardiovascular Pathology
  • Medical Imaging

Background:

  • Multi-phase post-mortem CT-angiography (MPMCTA) shows potential for improving post-mortem investigations, particularly in sudden death cases.
  • Standardization is needed to establish MPMCTA as a routine tool in forensic pathology.

Observation:

  • A study included 10 adult sudden unexpected death cases investigated between 2012 and 2013.
  • Non-contrast CT scans were performed before angiography, followed by MPMCTA.
  • Experienced radiologists interpreted MPMCTA findings, comparing them with autopsy results.

Findings:

  • MPMCTA demonstrated a strong correlation with autopsy findings in all 10 cases.
  • The combined approach of post-mortem CT and MPMCTA showed high diagnostic sensitivity.
  • MPMCTA proved advantageous in identifying causes of sudden death, irrespective of initial suspicion.

Implications:

  • MPMCTA can significantly contribute to the diagnostic accuracy of sudden death investigations.
  • This technique offers valuable insights into cardiovascular and ischemic events.
  • Further standardization could integrate MPMCTA as a routine component of the forensic pathology toolkit.
