Siemens Aera MRI scanner: what to know

The scanner records signals from tissues in the body and turns them into cross-sectional images. It does not use x-rays. The table moves through a short, open-ended tunnel, while the machine makes loud tapping or knocking sounds. Some examinations use contrast through a vein to make certain tissues easier to distinguish. The radiographer can speak with you and monitor you throughout the examination.

Tell the imaging team about a pacemaker, implanted pump, metal fragments, clips, hearing devices, pregnancy, kidney problems, allergies, or fear of enclosed spaces before the appointment. Remove jewellery, cards, keys, phones, and clothing with metal. Follow any fasting or medication instructions provided for your examination. During imaging, use the call button and follow breathing or stillness instructions; movement can blur the pictures.

Tell staff immediately if you feel unwell, unusually hot, short of breath, panicked, or unable to remain still. After contrast, report a widespread rash, facial swelling, wheezing, or severe dizziness urgently. A small amount of discomfort at an injection site should still be mentioned if it worsens. The scan itself should not cause pain, although lying in one position may be tiring.

Why is this body area being scanned? Will contrast be needed, and how should kidney concerns affect preparation? How long should I expect to remain in the scanner? When and how will the images be reviewed?
