Sample Drift Correction Following 4D Confocal Time-lapse Imaging10:04

Sample Drift Correction Following 4D Confocal Time-lapse Imaging

17.0K
Time-lapse microscopy allows the visualization of developmental processes. Growth or drift of samples during image acquisition reduces the ability to accurately follow and measure cell movements during development. We describe the use of open source image processing software to correct for three dimensional sample drift over...

Management of Respiratory Motion Artefacts in 18F-fluorodeoxyglucose Positron Emission Tomography using an Amplitude-Based Optimal Respiratory Gating Algorithm

6.1K
Amplitude-based optimal respiratory gating (ORG) effectively removes respiratory-induced motion blurring from clinical 18F-fluorodeoxyglucose (FDG) positron emission tomography (PET) images. Correction of FDG-PET images for these respiratory motion artefacts improves image quality, diagnostic and quantitative accuracy. Removal of respiratory motion artefacts is important for adequate clinical management of patients using...

Area of Science:

  • Cardiovascular Imaging
  • Medical Physics
  • Flow Dynamics

Background:

  • Respiratory motion significantly degrades the quality of thoracic 4D flow MRI data.
  • Current techniques often compromise scan efficiency or require gating, leading to unpredictable scan times.

Purpose of the Study:

  • To develop and evaluate a 4D flow MRI sequence minimizing respiratory motion artifacts.
  • To achieve predictable scan times with 100% scan efficiency for thoracic 4D flow MRI.

Main Methods:

  • A golden radial phase encoding (GRPE) 4D flow sequence was implemented in 9 healthy volunteers.
  • Respiratory motion was corrected retrospectively using self-navigation and k-t SENSE reconstruction.
  • GRPE datasets (motion-corrected and uncorrected) were compared to a Cartesian reference acquisition.

Main Results:

  • GRPE-motion-corrected (GRPE-MOCO) data showed no significant difference in aortic stroke volumes compared to Cartesian reference (CART-REF).
  • GRPE-MOCO demonstrated superior internal consistency accuracy compared to GRPE-uncorrected (GRPE-UNCORR) data.
  • Peak flow in GRPE-UNCORR was significantly different from CART-REF, highlighting the necessity of motion correction.

Conclusions:

  • The proposed GRPE 4D flow sequence enables straightforward planning and full thoracic coverage.
  • This method ensures predictable scan times, independent of breathing patterns and cardiac cycle variations.
  • GRPE-MOCO effectively minimizes respiratory motion artifacts in thoracic 4D flow MRI.
