A novel method models perfusion imaging markers using CT and MR data. This technique estimates bolus shape, dilation, and delay for improved analysis.

Area of Science:

  • Medical Imaging
  • Biomedical Engineering
  • Radiology

Background:

  • Perfusion imaging (CT and MR) is crucial for assessing tissue perfusion.
  • Accurate modeling of contrast agent dynamics is essential for quantitative analysis.
  • Existing modeling techniques may have limitations in capturing complex perfusion patterns.

Purpose of the Study:

  • To introduce a new computational approach for modeling perfusion imaging markers.
  • To evaluate the performance of this novel technique on Perfusion CT and Perfusion MR datasets.
  • To provide initial results demonstrating the feasibility and potential of the new method.

Main Methods:

  • The technique involves estimating the dilation and delay of an estimated contrast agent bolus shape.
  • A template fitting approach is applied to a new solution of the heat equation.
