Magnetic Resonance Imaging01:24

Magnetic Resonance Imaging

10.2K
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,...

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
  • Magnetic Resonance Imaging
  • Radiation Oncology

Background:

  • Previous MR guided radiation therapy (MRgRT) coil arrays were limited to 1-2 rows due to circuitry placement constraints.
  • Limited coil rows restrict parallel imaging undersampling in the head-foot direction, impacting MRgRT performance.
  • A three-row array with remote circuitry previously improved parallel imaging while maintaining SNR and radiolucency.

Purpose of the Study:

  • To evaluate a prototype four-row radiofrequency coil array for MRgRT.
  • To determine if a four-row design offers further parallel imaging advantages over existing MRgRT coil configurations.
  • To assess the feasibility of advanced coil designs for enhanced MRgRT capabilities.

Main Methods:

  • Developed remote circuits to position radio-opaque components outside the radiation beam path.
  • Engineered circuits included phase shifters, tuning, matching, detuning, and preamplifier decoupling.
  • Tested coil performance using an abdominal phantom and a 16-channel four-row array.

Main Results:

  • The four-row array achieved SNR comparable to two- and three-row designs.
  • Enabled 3x head-foot acceleration (min reciprocal g-factor = 0.74).
  • Supported 2x3 multi-directional acceleration (min reciprocal g-factor = 0.72), surpassing previous designs.

Conclusions:

  • Demonstrated the technical feasibility of four-row MRgRT coil arrays.
  • These designs can significantly benefit MRgRT applications demanding high SNR and temporal resolution.
  • The advanced coil configuration offers improved parallel imaging capabilities for radiation therapy.
