Summary

Fast spin-echo (FSE) MRI sequences are superior to gradient-spin-echo (GRASE) for detecting brain lesions due to better lesion conspicuity and lower noise. GRASE may be useful for visualizing hemosiderin or ferritin depositions.

Area of Science:

  • Radiology
  • Medical Imaging
  • Neuroimaging

Background:

  • T2-weighted MRI is crucial for detecting brain lesions.
  • Fast imaging techniques are needed to improve patient throughput and reduce motion artifacts.

Purpose of the Study:

  • To compare the efficacy of gradient-spin-echo (GRASE) and fast-spin-echo (FSE) sequences for fast T2-weighted brain MRI.
  • To evaluate lesion conspicuity, tissue contrast, and image artifacts between GRASE and FSE.

Main Methods:

  • Thirty-one patients with high-signal-intensity lesions underwent brain MRI at 1.5-T.
  • Both FSE and GRASE sequences with identical parameters were acquired and compared.
  • Quantitative analysis included signal-to-noise, contrast-to-noise, and contrast ratios.

Main Results:

  • FSE demonstrated more lesions with better overall conspicuity compared to GRASE.
  • Smaller lesions were better visualized with FSE due to lower noise and fewer artifacts.
  • Gray-white matter differentiation was superior on FSE images.
  • GRASE provided better contrast for ferritin and hemosiderin depositions, appearing darker.

Conclusions:

  • FSE is generally preferable for routine fast T2-weighted brain MRI due to superior lesion detection and image quality.
  • GRASE may be a valuable alternative for specific applications, such as assessing hemosiderin or ferritin deposition.
