Magnetic Resonance Imaging01:24

Magnetic Resonance Imaging

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...

Brain Imaging

Brain imaging technologies provide critical insights into both the structure and function of the human brain, enabling medical professionals and researchers to diagnose, study, and treat neurological disorders or psychiatric disorders more effectively.
These technologies include computerized axial tomography (CAT or CT scans), positron-emission tomography (PET scans),  magnetic resonance imaging (MRI),  functional magnetic resonance imaging (fMRI), and Transcranial Magnetic Stimulation (TMS).

Imaging Studies IV: Magnetic Resonance Imaging

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:

  • Magnetic Resonance Imaging
  • Neuroimaging
  • Biophysics

Background:

  • Functional magnetic resonance imaging (fMRI) traditionally relies on k-space encoding, limiting acquisition speed.
  • Ultrafast fMRI is crucial for capturing rapid neural dynamics and improving data quality.

Purpose of the Study:

  • Introduce and validate constrained source space imaging (CSSI) for ultrafast fMRI acquisition.
  • Demonstrate the potential of CSSI for improved hemodynamic response characterization.

Main Methods:

  • Localized magnetization signals using radiofrequency selective excitation and spatial coil sensitivities, bypassing k-space encoding.
  • Acquired data using a prototype dual-band stimulated echo acquisition mode excitation at TR = 250 ms.
  • Analyzed T2* decays for contrast enhancement and hemodynamic response characterization.

Main Results:

  • Successfully separated magnetization signals from localized voxels.
  • Demonstrated good characterization of hemodynamic responses in motor cortices (M1) and supplementary motor areas.
  • Validated CSSI for a functional magnetic resonance imaging motor task.

Conclusions:

  • Constrained source space imaging enables rapid, targeted fMRI acquisition without complex reconstruction.
  • CSSI has potential for sub-100 ms TR functional magnetic resonance imaging experiments and other MR signal contrast measurements.
