Magnetic resonance (MR) imaging offers real-time guidance for prostate procedures like biopsy and brachytherapy. Advanced image processing and robotic assistance enhance precision in targeted prostate therapies.

Area of Science:

  • Medical Imaging
  • Interventional Radiology
  • Oncology

Background:

  • Magnetic resonance (MR) imaging is a valuable tool for visualizing soft tissues.
  • Prostate interventions traditionally rely on transrectal ultrasound or CT, which have limitations in soft tissue contrast.
  • The development of open interventional MR systems allows for simultaneous patient access and real-time imaging.

Purpose of the Study:

  • To review the experience and utility of an open 0.5-T magnetic resonance (MR) interventional unit for guiding prostate procedures.
  • To highlight the capabilities of MR guidance for prostate biopsy and brachytherapy.
  • To discuss advancements in image processing and robotic assistance for targeted prostate therapy.

Main Methods:

  • Review of clinical experience using an open 0.5-T MR interventional unit for prostate interventions.
