Imaging Studies IV: Magnetic Resonance Imaging

114
Introduction:Magnetic Resonance Imaging, or MRI, can include a specialized imaging technique of the urinary system known as Magnetic Resonance Urography (MRU). This radiation-free technique uses strong magnetic fields and radio waves to produce detailed images with the help of a computer. MRU is particularly effective for visualizing fluid-filled structures like the kidneys, ureters, and bladder.Applications of MRI in the Genitourinary SystemKidneys and Ureters: MRI detects tumors, cysts,...

Magnetic resonance imaging (MRI) is a noninvasive medical imaging technique based on a phenomenon of nuclear physics discovered in the 1930s, in which matter exposed to magnetic fields and radio waves was found to emit radio signals. In 1970, a physician and researcher named Raymond Damadian noticed that malignant (cancerous) tissue gave off different signals than normal body tissue. He applied for a patent for the first MRI scanning device in clinical use by the early 1980s. The early MRI...

Introduction: MRI and CT scans are crucial advancements in medical imaging techniques, playing a vital role in diagnosing conditions related to the gastrointestinal (GI) system. Each scan serves distinct purposes, targets specific areas, and requires unique nursing duties.
Description of the Procedures
Computed Tomography (CT) scan:
Computed Tomography (CT) scans use X-ray technology to generate detailed images of bones, organs, and tissues. During the scan, the patient lies on a moving table...

Area of Science:

  • Medical Imaging
  • Oncology
  • Biopsy Technology

Background:

  • Prostate cancer is a leading cause of cancer death in US men, with significantly lower survival rates for advanced stages.
  • Early detection through screening and accurate diagnosis is crucial for improving patient outcomes.
  • Image-guided biopsies are essential for precise tissue sampling in prostate cancer diagnosis.

Purpose of the Study:

  • To assess the navigation accuracy of Promaxo's office-based Magnetic Resonance (MR) system for image-guided transperineal prostate biopsy.
  • To determine the feasibility of using this system in a clinical setting for prostate biopsies.

Main Methods:

  • A low-field MR system was used to image prostate phantoms with transperineally inserted needles.
  • Needle coordinates from the office-based MR system were compared against a 1.5T external reference scan (ground truth).
  • Navigation error was calculated as the distance from the planned target to the ground truth core center and trajectory.

Main Results:

  • The average error between the planned target and the ground truth core center was 2.57 ± 1.02 mm.
  • The average error for the actual core segment was 2.05 ± 1.24 mm.
  • Both error measurements were within the 95% confidence intervals.

Conclusions:

  • The average navigation errors were below the clinically significant threshold of 5 mm.
  • The Promaxo office-based MR system demonstrates feasibility for accurate prostate biopsies.
  • These initial phantom results support the potential of this system for clinical use in physician's offices.
