This study introduces a new protocol and software for MRI equipment quality assessment. The system ensures consistent MRI performance by analyzing key image parameters weekly over 3.5 years.

Area of Science:

  • Medical Imaging
  • Magnetic Resonance Imaging (MRI) Technology

Background:

  • Quality assessment is crucial for reliable MRI diagnostics.
  • Standardized protocols ensure consistent MRI performance and data integrity.

Purpose of the Study:

  • To develop and validate a protocol and software for automated MRI equipment quality assessment.
  • To monitor MRI performance metrics over time using a commercial test object.

Main Methods:

  • Developed a protocol and software for automated image analysis of MRI scans.
  • Utilized a commercial test object to assess signal-to-noise ratio, uniformity, distortion, slice thickness, profile, and resolution.
  • Performed weekly measurements on three Siemens MRI scanners (1.5T, 1.0T, 0.2T) over 3.5 years.

Main Results:
