您可以相信您在横幅健康中的所有成像程序，包括MRA和MRIS。主頁(欢迎您)这些测试是我们全面照顾的一部分，帮助我们的员工更好地了解您的条件，为您提供最佳的治疗方式。
MRI（磁共振成像）是一种非侵入性成像技术，其使用磁场和无线电波来创建体内器官和组织的详细图像。MRI机器使用磁场暂时重新重新调节身体中的水分子。无线电波然后导致原子产生微弱信号。然后使用这些信号来创建身体的横截面或3D图像。
除了传统的MRI机器外，横幅还使用开放式MRI和宽孔MRI机器：
An open bore MRI machine can be open on three or all sides of the machine. This type of MRI allows for patients who are claustrophobic or do not fit into a closed bore MRI. Open bore MRIs are best for extremities over the torso, organs or skull. An open bore MRI, however, takes longer and cannot reach the same image quality as a closed bore MRI as the magnetic field strength maxes out at 1.2 T.
宽孔MRI将闭孔MRI的好处与隧道内的更多空间结合在一起。这种类型的MRI提供优质图像，同时为患者提供更舒适的舒适性。
MRI用于检查器官，组织和骨骼系统，以诊断各种问题。通常，MRIS用作脑和脊髓的成像测试，也用作其他内脏的问题，如心脏，血管，骨骼和关节或乳房。
MRIS可以帮助诊断异常，包括：
什么是mra？
An MRA is a type of MRI that looks specifically at blood vessels. During an MRA, you will still be asked to lie in a large tube-shaped machine. In some cases, you may need to have a special dye added to your bloodstream to make blood vessels easier to see.
如果他们认为您在身体某处封锁或缩小血管缩小，您的医生可能需要MRA。MRAS使用磁场提供更详细的地查看内器官，而不是CT扫描，这需要辐射X射线。
你的医生可能还需要一个查看:
在您的MRA或MRI之前，除非另有指示，您将能够正常吃并服用通常的药物。您将被问到您是否有可能会干扰MRI机器的任何条件或问题。这些可以包括：
如果您在MRA或MRI考试之前有任何这些问题，请与您的医生交谈。
An MRI is painless, but you will hear loud noises during the procedure. You may be given earplugs or ear protection of some sort. For MRAs, you will likely need a contrast agent, which will be injected into your veins prior to the exam.
在测试期间，您将躺在桌子上滑入MRI管的开口。您将拥有一名技术专家指导和与您交谈的另一个房间。如果你是幽闭恐惧症，你可能会有一种药物来帮助缓解焦虑。
The machine will produce magnetic waves around you while radio waves are directed at your body. You will be asked to remain still for the duration of your procedure. The combination of these waves will produce images of the body on the technologist’s screen. You may be asked to perform small tasks, like answering simple questions, to locate the portions of the brain that control these functions.
Depending on what is being analyzed, an MRI can last from 15 minutes to an hour. Unless you have been sedated, you can resume normal activities immediately after the scan.
虽然MRA和MRI程序是无痛和无侵入性的，但您可能会遇到一些罕见的风险，包括：
一旦放射科学家分析和解释了您的图像，他们将向您的医生报告他们的研究结果。您的医生将汇复向您讨论任何重要调查结果并提供后续步骤。
您可以在横幅保健医院，诊所或许多方便的横幅成像位置获得MRI或主頁(欢迎您)MRA。
