CI.E Produce Magnetic Resonance images for diagnostic purposes

Overview

This standard is concerned with the use of Magnetic Resonance imaging (MRI) equipment and procedures to produce images for diagnostic purposes.

Users of this standard will need to ensure that practice reflects up to date information and policies

Version No 1

    6. use of medical devices and product liability
    7. security within the workplace
    8. consent to magnetic resonance examinations
    9. patient identification
    10. data entry, utilisation, recording and transfer
  2. your responsibilities and accountability under the current European and national legislation and local policies and protocols
  3. limitations of own knowledge and experience and the importance of not operating beyond this
  4. the roles and responsibilities of other team members
  5. clinical justification of the examination request
  6. the information that should be given to patients:
    1. before commencing the examination
    2. during the examination
    3. on completion of the examination
  7. contra-indications, including absolute and relative, to Magnetic Resonance scanning including the clinical implications of any allergy relevant to the examination
  8. the gross, surface and cross-sectional anatomy of the areas to be scanned
  9. medical terminology relevant to the examination, including abbreviations

  11. the common normal variants and their appearance on Magnetic Resonance images
  12. common pathologies of the areas to be scanned and their appearance on Magnetic Resonance images
  13. manifestations of patients’ physical and emotional status
  14. when additional images are required to aid diagnosis and to enhance the examination
  15. the principles of Magnetic Resonance physics
  16. controlled areas and safety requirements in the Magnetic Resonance environment
  17. the ways in which Magnetic Resonance images can be captured, processed, transferred and permanently stored
  18. the physical principles of Magnetic Resonance scanning including number of acquisitions, number of slices and Magnetic Resonance contrast media
  19. the process involved in the production of Magnetic Resonance images, scanning techniques and protocols
  20. technical and diagnostic quality requirements of the image
  21. artefacts on images - their causes and avoidance strategies
  22. factors which influence the decision to repeat images or take additional images
  23. alternative imaging examinations
  24. safe operation of the Magnetic Resonance scanner and accessories in use
  25. the use of quality assurance (QA) equipment, recording results and taking appropriate action
  26. equipment capabilities, limitations and routine maintenance including the quality control processes required by the operator
  27. the importance of timely equipment fault recognition and local procedures for reporting these
  28. patient preparation procedures for Magnetic Resonance scanning
  29. the importance of checking for presence of metallic objects/prostheses, including cardiac pacemakers, and the appropriate action to take
  30. preparation of environment and equipment for Magnetic Resonance scanning
  31. patient and equipment positioning, including those required for comfort and immobilisation, relevant to examination being performed
  32. local procedures and procedures pertaining to recording, collating and preparing appropriate patient documentation and images for transfer or storage according to local protocols

Performance Criteria

You must be able to do the following:

  1. apply standard precautions for infection prevention and control and other appropriate health and safety measures
  2. receive the patient and check his/her identification details in accordance with local protocols
  3. check for Magnetic Resonance imaging safety by use of the department Magnetic Resonance imaging safety check list which will include checking for the presence of metallic objects/prostheses, including cardiac pacemakers, and take appropriate action
  4. examine previous relevant images and clinical information, where available, to ensure that the correct procedure and techniques are employed
  5. assess the patient’s clinical and physical condition prior to the start of the examination with a view to proceeding
  6. check females of child-bearing age for pregnancy or potential pregnancy, if appropriate to the examination, and take action in accordance with local protocols
  7. confirm the status of carers before the examination and, where their presence is required, adhere to local guidelines and rules
  8. enter the identification details of the patient into the Magnetic Resonance scanner or, if previously entered, check for accuracy
  9. accurately select all sequences required for the scan according to local protocols for the procedure, assess and any required modifications and take appropriate action
  10. position the patient and adjust their clothing according to the protocols for the examination to be performed in a manner which allows an optimal outcome to be achieved while:
    1. recognising the patient’s need to retain their dignity and self respect
    2. ensuring his/her comfort as far as possible
    3. preventing the appearance of artefacts
  11. correctly and safely position appropriate Radio Frequency (RF) coils
  12. check the room prior to taking the scan to ensure that only essential protected persons remain and that all local rules have been adhered to, taking appropriate action where necessary
  13. commence the scan and monitor the patient’s condition and compliance throughout the procedure and take action appropriate to the his/her needs
  14. review the images on completion of the scan to ensure they are technically acceptable and suitable for diagnostic purposes
  15. review images for clinical acceptability, take appropriate action, including further imaging if required
  16. inform the patient or carer of the results procedure and answer any questions or refer them to the appropriate person
  17. refer to the referring clinician or departmental radiologist if an abnormality is observed on the image which is likely to require further investigation or treatment, following departmental protocols
  18. optimise, record, collate and prepare appropriate patient documentation and images for transfer or storage according to local protocols
  19. recognise where help or advice is required and seek it from appropriate sources
