Magnetic Resonance Imaging

5.3K
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...

The number of nuclear spins aligned in the lower energy state is slightly greater than those in the higher energy state. In the presence of an external magnetic field, as the spins precess at the Larmor frequency, the excess population results in a net magnetization oriented along the z axis. When a pulse or a short burst of radio waves at the Larmor frequency is applied along the x axis, the coupling of frequencies causes resonance and flips the nuclear spins of the excess population from the...

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,...

Area of Science:

  • Biomedical Engineering
  • Medical Imaging
  • Quantitative MRI

Background:

  • Conventional magnetic resonance imaging (MRI) sequences utilize static parameters, which may not be optimal for individual subjects.
  • This can lead to longer acquisition times and potential inefficiencies in data collection.

Purpose of the Study:

  • To design and evaluate a novel, personalized adaptive MRI approach.
  • To demonstrate real-time adjustment of pulse sequence parameters based on incoming subject data.

Main Methods:

  • Implemented an adaptive, real-time multi-echo (MTE) experiment for T2* estimation.
  • Combined a Bayesian framework with model-based reconstruction for parameter optimization.
  • Continuously updated prior distributions of tissue parameters to guide sequence parameter selection.

Main Results:

  • Computer simulations predicted 1.7- to 3.3-fold acceleration compared to static sequences.
  • Phantom experiments corroborated simulation predictions.
  • Healthy volunteers showed a 2.5-fold acceleration in T2* measurement for n-acetyl-aspartate.

Conclusions:

  • Adaptive pulse sequences offer substantial reductions in MRI acquisition times.
  • The proposed adaptive framework is generalizable to other MRI and magnetic resonance spectroscopy (MRS) applications.
  • Motivates further research into adaptive, model-based approaches for accelerated imaging.
