如何用英文向病人解释MRI并告知注意事项
摘要: MRI(磁共振成像)是一种不使用辐射的医学影像技术,通过强磁场和无线电波生成身体内部结构的高对比度详细图像,常用于脑部、脊柱、心脏及肿瘤等疾病的诊断。向患者解释MRI时,应说明其安全性、检查过程、所需配合事项及注意事项,以减轻焦虑并确保检查顺利进行。
- MRI不使用电离辐射,比X光和CT更安全,尤其适用于软组织成像。
- 患者需在检查前完成安全问卷,并移除所有金属物品,包括衣物上的金属配件。
- 检查过程中需保持静止,可能听到较大噪音,医院会提供耳塞或耳机。
- 如有幽闭恐惧症,可提前请医生开具镇静药物;检查期间可通过报警按钮与技师沟通。
- 部分MRI需注射造影剂,若注射时感到不适应立即告知技术人员。
小白老师说:MRI has become the preferred procedure for diagnosing a large number of potential problems in many different parts of the body. It’s quite a skill for doctors to explain** to patients what MRI is used for, how safe it is and prepare them for an MRI.
How do you prepare patients for Magnetic Resonance Imaging (MRI)?
Patient safety tips prior to the procedure
MRI is safer than X-rays because it does not use radiation. It provides more information than Computed Tomography about some head, neck and spinal disorders because the images are more detailed and have more contrast, meaning the differences between dark and light areas are stronger. Unlike CT, the images can be taken on any plane—any surface of the body seen from an angle. It is now used for imaging—taking images of—the brain and heart, and in oncology.
You will need to have completed a safety questionnaire and have it with you. It is important that there is no metal on your clothing or person. Prior to the scan you can eat and drink normally. Your details and safety questionnaire will be checked with you by the radiographer, who will explain the procedure and answer any questions you may have. You will be asked to remove any metallic objects, as well as credit cards.
Other Tips
1. Please leave your valuables at home, including jewelry, to prevent it from being lost or stolen, for they have to be removed prior to entering the scan room.
2. If you don’t want to change into hospital attire, please wear cotton clothing without any metal zippers, hooks, or buttons.
3. Please let us know if you need interpreting services, this can be arranged for you.
4. Please bring a list of your current medications.
5. If you have claustrophobia, your doctor may prescribe an oral medication for you to take with you for your MRI appointment.
How do you explain to a patient what happens during the MRI scan?
The duration of the procedure will vary but the average is 45 minutes to one hour per body part.
You will be required to lie still during the actual MR scanning. Depending on the body part that is being examined, you may be instructed to hold your breath for up to 30 seconds.
The magnet is permanently open on both ends. It is well lit and there is a fan for patient comfort. There is also a two way intercom system for communication between patient and technologist. The part of the body being scanned will be placed in the middle of the magnet.
During the actual imaging, you will hear a loud intermittent banging noise. You will be provided with earplugs or head phones to minimize the noise during the procedure.
The technologist will also provide you with an alarm button to alert the technologist of any discomfort you may experience at any point during the MRI exam.
Some MRI exams require an injection of intravenous MRI contrast. Inform the technologist if you experience any discomfort during the injection.
常见问题
MRI检查有辐射吗?
没有。MRI使用强磁场和无线电波,不涉及电离辐射,因此比X光或CT更安全。
做MRI前可以吃饭喝水吗?
可以。除非医生特别指示,否则MRI检查前可正常饮食。
为什么不能带金属物品进入MRI室?
MRI设备使用强磁场,金属物品可能被吸引造成危险,或干扰图像质量。
MRI检查会很吵吗?
是的,扫描时会产生间歇性敲击声,但医院会提供耳塞或耳机以降低噪音。
如果我有幽闭恐惧症怎么办?
可提前告知医生,医生可能会开具口服镇静药物帮助您完成检查。
