What should you know about old mri scanner?

MRI uses a strong magnetic field and radio waves to create detailed images without ionising radiation. Scanner age alone does not determine whether a scan is appropriate. Image quality depends on the scanner’s field strength, coils, software, maintenance and the body area being examined. A radiologist may decide that an older machine is adequate for the clinical question or may recommend a different facility if more specialised imaging is needed.

Older equipment can also have a narrower opening, longer scan sequences or more noticeable noise. Tell the team about metal fragments, implants, pacemakers, hearing devices, pregnancy, kidney problems and previous reactions to contrast. The safety questionnaire is essential even when you have had MRI before.

Ask the imaging centre whether the scanner is suitable for the body part and question being investigated, whether contrast is planned, and how long the appointment may take. Bring implant details if available and remove metal objects before entering the scan room. During the examination, you can usually communicate with the technologist and receive an alarm button. Tell them if you feel uncomfortable, overheated or distressed.

Tell the imaging team immediately if you feel unwell during the scan, especially with breathing trouble, swelling, severe dizziness, chest discomfort or a sudden allergic-type reaction after contrast. After leaving, seek urgent help for worsening breathing difficulty, facial swelling, fainting or severe weakness. Contact the centre about a delayed rash, persistent vomiting or other unexpected symptom so they can advise you.

Is this scanner suitable for the area being examined? Will contrast be needed, and do I need kidney testing? Could my implant or metal exposure affect safety? Would a breast MRI or another MRI service provide information that this scan cannot? When and how will the images be reviewed?
