Wired active MR microcoils effectively correct head motion in brain PET scans, significantly improving image accuracy and contrast. This method reduces activity concentration bias and enhances image correlation compared to uncorrected scans.

Area of Science:

  • Medical Imaging
  • Neuroscience
  • Biophysics

Background:

  • Head motion during brain positron emission tomography (PET) scans introduces significant artifacts, challenging accurate quantitative analysis.
  • Motion artifacts compromise image quality and can lead to misinterpretations in clinical diagnoses.

Purpose of the Study:

  • To investigate the feasibility of using wired active MR microcoils for real-time head motion tracking.
  • To integrate motion data into iterative PET reconstruction for artifact reduction.

Main Methods:

  • Developed specialized wired active MR microcoils and a dedicated MR coil-tracking sequence.
  • Attached microcoils to an anthropomorphic phantom for simulated brain PET scans under controlled motion.
  • Acquired simultaneous PET list-mode and MR tracking data on a PET-MR scanner.

Main Results:

  • Motion correction using MR microcoils effectively removed motion artifacts, reducing activity concentration bias from -25.0%–16.6% to -0.6%–3.4%.
  • Contrast recovery improved by 37%–156% with motion correction.
  • Image correlation with a static reference improved significantly (R² = 0.978 ± 0.007) compared to uncorrected scans (R² = 0.588 ± 0.010).

Conclusions:

  • Wired active MR microcoil based motion correction substantially enhances quantitative accuracy in brain PET imaging.
  • This technique significantly improves image contrast and reduces motion-induced artifacts.
