Magnetic Resonance Imaging01:24

Magnetic Resonance Imaging

10.5K
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 IV: CMRI

550
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,...

  • To highlight specific applications where 3 T MR imaging offers significant advantages.

Main Methods:

  • Clinical implementation and assessment of 3 T MR imaging systems.
  • Comparative analysis of image quality metrics (signal/noise ratio, contrast/noise ratio) between 1.5 T and 3 T.
  • Evaluation of advanced MR techniques, including functional MR imaging (fMRI), at 3 T.

Main Results:

  • 3 T MR imaging is clinically feasible and demonstrates improvements over 1.5 T.
