Imaging Studies for Cardiovascular System IV: CMRI

542
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,...

Magnetic Resonance Imaging

7.6K
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...

Imaging Studies for Cardiovascular System V: CT

674
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...

Mitral Stenosis II: Clinical features and Diagnostic Tests

565
Mitral stenosis is a heart condition in which the mitral valve, which allows blood to flow from the left atrium to the left ventricle, becomes narrowed or stenotic. This narrowing hinders blood flow and leads to clinical symptoms requiring specific medical evaluations and management strategies. The following overview outlines the clinical symptoms, assessments, diagnostic findings, prevention methods, and treatments for mitral stenosis.Clinical ManifestationsDyspnea (shortness of breath): This...

Pulse rhythm01:30

Pulse rhythm

1.7K
Pulse rhythm refers to the pattern of pulsations within specific intervals, offering valuable insights into the regularity or irregularity of the heart's beats as observed through the pattern of pulsation within specific intervals. A regular pulse exhibits a consistent heart rate with uniform waveforms and pulsation force, variations of which can be classified as normal, weak, or bounding.
Conversely, an irregular pulse pattern is termed dysrhythmia, stemming from disruptions in cardiac...

Area of Science:

  • Cardiovascular Imaging
  • Medical Device Technology

Background:

  • Cardiac implantable electronic devices (CIEDs) traditionally contraindicate MRI scans.
  • MRI-conditional pacemakers offer potential for expanded MRI accessibility in pacemaker patients.

Observation:

  • A 62-year-old male patient with acute coronary syndrome and atrial fibrillation underwent pacemaker implantation.
  • A dual-chamber, MRI-conditional pacemaker system was implanted due to sinus node dysfunction.

Findings:

  • Cardiovascular MRI was successfully performed 6 weeks post-implantation.
  • Diagnostic quality images of an anterior myocardial infarction were obtained despite the presence of the pacemaker.

Implications:

  • This demonstrates the feasibility of cardiovascular MRI in patients with MRI-conditional pacing systems.
  • It highlights the potential for improved diagnostic capabilities in pacemaker patients.
  • Further research into MRI safety and efficacy with CIEDs is warranted.
