This study introduces efficient MRI quality control methods using AAPM protocols. It proposes practical tools for analyzing DICOM images to ensure scanner performance and identify malfunctions in clinical settings.

Area of Science:

  • Medical Imaging Physics
  • Radiology Quality Assurance

Background:

  • Quality control (QC) in Magnetic Resonance Imaging (MRI) encompasses initial acceptance testing and ongoing performance monitoring.
  • Acceptance tests verify procurement specifications but are time-consuming.
  • Clinical practice requires efficient QC methods to detect equipment malfunctions without disrupting workflow.

Purpose of the Study:

  • To evaluate the feasibility of established AAPM (American Association of Physicists in Medicine) protocols for MRI QC.
  • To propose practical procedures and tools for efficient MRI scanner performance evaluation and malfunction detection.

Main Methods:

  • Utilized AAPM QC protocols (1,2).
  • Captured MRI images in DICOM (Digital Imaging and Communications in Medicine) format.
