2. Preparation for breast magnetic resonance imaging
Performer: radiologist and radiologist specialized in radiology. Equipment: Resonator 3.0 Tesla Medicine: can be used to support sedation in cases of patients with fear of the dark, claustrophobia of narrow spaces. Patient: You will be assigned by your doctor to do a checklist on magnetic resonance safety before the scan. Before the scan, the technician or the doctor in the magnetic resonance room will check the checklist again to make sure it is safe to take the MRI.
You will be asked to remove jewelry, watches, credit cards, pins, hair clips, metal zippers, phones and similar metal items before entering the studio. Implantable medical devices can be damaged when entering the MRI room, so during the pre-exam MR safety checklist, the technician or doctor will ask you about this.
Then you need to wear a hospital gown. Pre-scan preparations such as eating and drinking instructions before MRI vary from case to case. If your doctor does not recommend fasting or fasting, you can eat and drink as usual before the scan.
In the case of contrast agents, you may need blood tests to determine if your kidneys are working properly. You will have an intravenous line placed in your arm or forearm before the scan. Your doctor will take your allergy history into account before deciding to use contrast agent.
