New PET/CT imaging requires advanced software for effective interpretation and communication. Current tools are complex, limiting physician navigation and data sharing, hindering wider clinical adoption.

Area of Science:

  • Medical Imaging
  • Radiology
  • Nuclear Medicine

Background:

  • Multimodality imaging scanners combining Positron Emission Tomography (PET) and Computed Tomography (CT) offer new paradigms in image display.
  • Overlaying functional (PET) and anatomical (CT) data presents challenges in interpretation software, navigation, and communication.

Purpose of the Study:

  • To highlight the challenges and requirements for effective interpretation and communication of multimodality PET/CT imaging data.
  • To discuss the need for improved software tools for navigation and data visualization.

Main Methods:

  • PET/CT scanners acquire spatially registered images simultaneously.
  • Specialized reconstruction software and display programs are needed to overlay PET data (color-coded) onto CT images.

  • Interactive multidimensional navigation techniques are required to visualize data across spatial and temporal dimensions.

    • Main Results:

    • Color overlay techniques enable visual identification of high tracer activity and underlying anatomy.
    • Current software is often complex, requiring time-consuming manipulation for diagnostic interpretation.
    • Limited viewing software hinders the effective communication of fused PET/CT images to referring physicians.

    Conclusions:

    • Wider adoption of PET/CT depends on developing better image display and navigation tools for efficient multi-dimensional data interpretation.
    • Improved interactive tools are necessary for sharing and reviewing multimodality data with referring physicians and care providers.
    • Current static images of fused data are inadequate for comprehensive visualization.
