Magnetic Resonance Imaging

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...

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.
