When undergoing an MR (Magnetic Resonance) scan, a powerful magnetic field temporarily realigns hydrogen atoms in the body. Radio waves are then used to generate signals, which are processed to create detailed images of specific organs and tissues.
Generally, no extensive special preparation is required for an MR scan. Patients can typically eat and take their medications as usual before the procedure. You will be asked to complete a form regarding your medical history before the scan.
Due to the strong magnetic field generated by the MR scanner, it is crucial that no metallic objects are brought into the MR room or worn by the patient. All items containing metal, such as watches, credit cards, metal jewelry, hairpins, glasses, dentures, hearing aids, and bras with metal components, must be removed before entering the scan room. Unless otherwise instructed, you may empty your bladder before the scan if it is full.
The patient lies on a movable table that slides into the tube-shaped MR scanner, which is typically open at both ends. A radiologist or technologist will monitor you from an adjacent room and communicate via a microphone. The MR device's narrow, tube-like appearance can be challenging for individuals with claustrophobia; appropriate patients may be offered a sedative.
The MR scan is a painless procedure, and its duration varies depending on the specific imaging required, typically ranging from 15 to 60 minutes. To ensure optimal image quality, it is essential to remain still throughout the entire scan. Any movement can affect the clarity of the images. The MR scanner produces loud knocking or buzzing noises during operation; to minimize discomfort, headphones or earplugs will be provided. For certain types of MR scans, a contrast agent may be administered intravenously to enhance image clarity and provide more detailed information.
