Hybrid imaging, combining radiology scanners with endoscopy or ultrasound, enhances interventional microtherapy. This allows real-time instrument guidance, improving minimally invasive procedures and potentially reducing costs.

Area of Science:

  • Radiology and Medical Imaging
  • Minimally Invasive Surgery
  • Interventional Microtherapy

Background:

  • Radiologic diagnostic scanners like MRI, CT, and EBCT are increasingly used for interventional microtherapy.
  • These scanners enable transparent visualization of the therapeutic field during procedures.
  • Hybrid imaging techniques combine tomographic scanners with endoscopy, fluoroscopy, angiography, and ultrasound.

Purpose of the Study:

  • To evaluate hybrid imaging suites for interventional microtherapy procedures.
  • To determine the optimal imaging approach for various minimally invasive interventions.
  • To assess the potential for improved instrument guidance and reduced complications.

Main Methods:

  • Integration of Magnetic Resonance Imaging (MRI), Computed Tomography (CT), and Electron Beam Tomography (EBCT) scanners.

  • Combination with endoscopy, fluoroscopy/digital subtraction angiography, and ultrasound for hybrid imaging.
  • Utilizing therapeutic systems such as lasers and radiofrequency alongside imaging guidance.

    • Main Results:

    • MRI provides 3D localization without ionizing radiation exposure.
    • Open access and keyhole imaging facilitate near real-time instrument guidance.
    • Minimally invasive techniques with hybrid tomographic guidance improve microinstrument tip tracking and reduce complications.

    Conclusions:

    • Hybrid imaging suites offer safer access for minimally invasive procedures.
    • These techniques support interdisciplinary cooperation and have the potential for significant cost reductions.
    • The study identifies suitable hybrid imaging approaches for procedures like drug instillations, stent implantation, and microoperations.
