This study developed a virtual reality visualization method for fast breast MRI analysis. The system enhances lesion detection and localization by integrating functional and anatomical data.

Area of Science:

  • Medical Imaging
  • Radiology
  • Biophysics

Background:

  • Breast MRI is increasingly used alongside mammography.
  • Analyzing dynamic contrast-enhanced MRI requires efficient methods.
  • Understanding microcirculation is key for breast cancer detection.

Purpose of the Study:

  • To develop a fast and efficient method for analyzing dynamic breast MRI series.
  • To enable simultaneous visualization of morphological and functional tissue information.
  • To improve the detection and localization of breast lesions.

Main Methods:

  • Acquisition of dynamic saturation-recovery-turbo-FLASH and morphological 3D-FLASH MRI datasets.
  • Analysis of dynamic data using tracer kinetic modeling for microcirculation parameters.

  • Development of a multidimensional real-time virtual reality visualization system with 3D-texture mapping.

    • Main Results:

    • The developed system allows for spatially differentiated representation of functional parameters superimposed on anatomical information.
    • Enhanced discernibility of contrast enhancement and improved lesion localization in 3D space.
    • Feasibility study confirmed the practicability of multidimensional virtual reality visualization for contrast enhancement analysis.

    Conclusions:

    • Multidimensional visualization of contrast enhancement in virtual reality is a practical approach for breast MRI analysis.
    • The system facilitates intuitive human-computer interaction and improved recognition of topological coherencies.
    • This method shows significant potential for detecting and localizing multiple breast lesions efficiently.
