Insights

128-slice dual-source CT coronary angiography offers accurate, non-invasive assessment of coronary artery disease (CAD). This advanced cardiac imaging technique provides high sensitivity and specificity, aiding in the diagnosis of CAD.

Area of Science:

  • Cardiology
  • Radiology
  • Medical Imaging

Background:

  • Coronary artery disease (CAD) is a leading cause of morbidity and mortality globally and in India.
  • Invasive catheterization remains the gold standard for CAD evaluation.
  • Advancements in cardiac imaging, such as 128-slice dual-source CT, are crucial for 21st-century diagnostics.

Purpose of the Study:

  • To evaluate the diagnostic accuracy of 128-slice dual-source CT coronary angiography.
  • To compare CT coronary angiography with conventional catheter coronary angiography.

Main Methods:

  • Forty patients with suspected CAD underwent both CT coronary angiography and conventional catheter coronary angiography.
  • Siemens 128-slice Dual Source Flash Definition CT scanner was utilized.
  • Patient heart rates influenced the CT scanning mode (Retrospective or Prospective).

Main Results:

  • A total of 600 out of 609 segments were assessable via CT coronary angiography.
  • The study reported a specificity of 95.12%.
  • Sensitivity and positive predictive value were 95.26% and 88.46%, respectively, with 21 false positives and 8 false negatives.

Conclusions:

  • 128-slice dual-source CT scanner enables accurate non-invasive assessment of coronary artery disease.
  • This technology presents a viable alternative to invasive diagnostic procedures for CAD.

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...

Acute Coronary Syndrome III: Diagnostic Studies

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

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...

Cardiac Catheterization I: Pre-Procedure Overview

Cardiac catheterization is an invasive diagnostic technique used to identify and evaluate structural and functional diseases of the heart and major blood vessels. This technique diagnoses congenital heart disease, coronary artery disease, valvular heart disease, and coronary spasms and assesses ventricular function. It helps guide treatment decisions, including the need for revascularization procedures like percutaneous coronary intervention (PCI) or coronary artery bypass grafting (CABG) and...
