Magnetic Resonance Imaging01:24

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...

Introduction:Magnetic Resonance Imaging, or MRI, can include a specialized imaging technique of the urinary system known as Magnetic Resonance Urography (MRU). This radiation-free technique uses strong magnetic fields and radio waves to produce detailed images with the help of a computer. MRU is particularly effective for visualizing fluid-filled structures like the kidneys, ureters, and bladder.Applications of MRI in the Genitourinary SystemKidneys and Ureters: MRI detects tumors, cysts,...

Two-Dimensional (2D) NMR: Overview

1.6K
The 1D NMR spectrum of large and complex molecules like natural products has complicated splitting patterns and overlapping signals, which can be easily interpreted using 2-dimensional (2D) NMR. Unlike 1D NMR, 2D NMR has two frequency axes that provide the coupling information between the nucleus A and nucleus B in a molecule. The process from which 2D spectra are obtained has four steps.
The first step is the preparation period, during which nucleus A is excited with a radiofrequency pulse....

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,...

Area of Science:

  • Medical Imaging
  • Biomedical Engineering
  • Physics

Background:

  • Magnetic Resonance Imaging (MRI) is a leading brain imaging modality.
  • Current MRI systems are large, heavy, and require specialized facilities.

  • Replaced gradient encoding with a rotating, lightweight, cryogen-free, low-field magnet (rSEM).
  • Utilized multiple receive channels to disambiguate the non-bijective encoding field for 2D image reconstruction.

Main Results:

  • Validated the system with experimental images of 2D test phantoms.
  • Achieved position-dependent spatial resolution, with central blurring, deemed sufficient for many medical applications.
  • Demonstrated successful proof-of-concept imaging with the novel architecture.

Conclusions:

  • The portable MRI scanner demonstrates feasibility by relaxing magnet homogeneity requirements and eliminating gradient coils.
  • The new architecture and encoding scheme offer a viable path toward more accessible MRI.
