Insights

T1-weighted inversion recovery MRI can detect T1 hyperintensity in coronary artery plaques, indicating intraplaque hemorrhage. This imaging technique shows promise for non-invasive characterization of atherosclerotic plaques in coronary artery disease patients.

Area of Science:

  • Cardiovascular Imaging
  • Radiology
  • Biomedical Engineering

Background:

  • Intraplaque hemorrhage (IPH) is a critical factor in atherosclerotic plaque instability.
  • Pre-contrast T1-weighted magnetic resonance imaging (MRI) shows potential for detecting IPH in atherosclerotic plaques.

Purpose of the Study:

  • To evaluate T1 hyperintensity in coronary artery plaques of patients with coronary artery disease (CAD).
  • To correlate T1 hyperintensity findings with multi-detector computed tomography (MDCT) characteristics.

Main Methods:

  • Fifteen CAD patients underwent MDCT and T1-weighted inversion recovery (IR) MRI.
  • Plaques were analyzed for Hounsfield number (MDCT) and signal intensity (MRI).
  • Regions of interest were defined for signal and density measurements.

Main Results:

  • Forty-three plaques were identified; 12% showed T1 hyperintensity on IR-MRI.
  • Hyperintense plaques had higher signal-to-noise and contrast-to-noise ratios.
  • Hyperintense plaques demonstrated significantly lower CT density compared to hypointense plaques.

Conclusions:

  • T1-weighted IR-MRI is a potential tool for non-invasively detecting intraplaque hemorrhage in coronary artery plaques.
  • This technique may aid in the characterization of atherosclerotic plaques in CAD.

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 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,...

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...
Magnetic Resonance Imaging01:24

Magnetic Resonance Imaging

Magnetic resonance imaging (MRI) is a noninvasive medical imaging technique based on a phenomenon of nuclear physics discovered in the 1930s, in which matter exposed to magnetic fields and radio waves was found to emit radio signals. In 1970, a physician and researcher named Raymond Damadian noticed that malignant (cancerous) tissue gave off different signals than normal body tissue. He applied for a patent for the first MRI scanning device in clinical use by the early 1980s. The early MRI...

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...
