Magnetic Resonance Imaging

10.6K
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...

Area of Science:

  • Magnetic Resonance Imaging (MRI)
  • Medical Imaging Technology
  • Biomedical Engineering

Background:

  • Compact portable low-field MRI systems face challenges with image distortions.
  • Field inhomogeneity and gradient nonlinearity severely impact imaging quality in these systems.

Purpose of the Study:

  • To develop and evaluate a novel Multi-Shot Multi-Echo cross-term Spatiotemporal Encoding (MS-ME xSPEN) sequence.
  • To enhance imaging performance in compact, portable low-field MRI systems.
  • To maintain the robustness of xSPEN techniques against severe field inhomogeneities.

Main Methods:

  • Implemented MS-ME xSPEN using segmented and interleaved image-domain multi-shot sampling.
  • Selected the segmented MS-ME xSPEN approach for evaluation.
  • Compared segmented MS-ME xSPEN with conventional single-shot xSPEN on a 110-mT portable MRI system.
  • Emulated a constant gradient environment by activating a single gradient axis.

Main Results:

  • MS-ME xSPEN demonstrated superior resilience to in-plane distortions caused by field inhomogeneities.
  • The new sequence achieved a higher signal-to-noise ratio (SNR) compared to standard xSPEN.
  • MS-ME xSPEN provided a wider range of T2-weighted contrasts.
  • Imaging was successfully performed on phantoms and the human brain.

Conclusions:

  • MS-ME xSPEN is well-suited for compact portable MRI systems.
  • The sequence offers improved SNR, flexible contrast options, and robustness to field inhomogeneity.
  • This advancement holds promise for improving diagnostic capabilities in portable MRI applications.
