A survey of MRI quality assurance programmes

Area of Science:

• Medical Imaging
• Radiology
• Healthcare Quality Management

Background:

• No established national guidelines exist for quality assurance (QA) test frequencies in clinical Magnetic Resonance Imaging (MRI) equipment.
• Variability in MRI QA practices can impact equipment performance and diagnostic accuracy.
• Standardization of MRI QA is crucial for maintaining high standards in clinical settings.

Purpose of the Study:

• To investigate current MRI quality assurance (QA) practices in English hospitals.
• To determine the range and frequency of QA tests performed.
• To identify staff groups responsible for conducting MRI QA tests.

Main Methods:

• A survey was conducted among 35 hospitals in England selected randomly.
• Questionnaires were distributed to gather data on MRI QA test frequencies, types, and personnel.
• A response rate of 68% was achieved, with 24 completed replies analyzed.

Main Results:

• 79% of responding hospitals perform some form of MRI QA, primarily by radiographic staff.
• Significant variation exists in the frequency and scope of QA tests across institutions.
• Signal-to-noise ratio (SNR) tests were commonly performed on head and body coils, but less frequently on other coils.

Conclusions:

• Current MRI QA practices in England are inconsistent, lacking national standardization.
• Survey results provide insights into existing QA approaches, informing departmental practices.
• There is a clear need to develop and implement standardized MRI QA programs.
