Increasingly, however, and similar to how radiologists have had the ability to read electronic studies remotely, new software options from many of the leading MRI manufacturers now allow the operating MRI technologist to be in an entirely different location from where the images are being acquired.

With the MRI technologist located remotely sometimes controlling two or more remote MRI scanners simultaneously , standards of point-of-care workflow and responsibilities have not yet been clearly defined.

The new section on remote scanning seeks to lay out an alternative path for remote scanning safety without entirely rewriting guidance for point-of-care scanning.

One of the challenges, however, is the multiplicity of ways that remote scanning can be deployed eg, technical, teaching, expert model, and full operation.

The sections of the proposed draft that cover remote scanning are largely dedicated to a discussion of staffing location, with comparatively little discussion devoted to how workflows, decision making, and communications would be required to change under remote scanning.

This necessitates alternative sets of standards as well as careful integration of MRI safety practices within the area s where the MRI scanner is operating. Ultimately, however, the next edition of the ACR Manual on MR Safety can likely be expected to continue defining the standard of care with respect to MR imaging performance and safety.

At all times, you will be monitored and you will be able to communicate with the MRI technologist using an intercom system or by other means. MRI is the preferred procedure for diagnosing a large number of potential problems or abnormal conditions that may affect different parts of the body.

In general, MRI creates pictures that can show differences between healthy and unhealthy or abnormal tissues. Physicians use MRI to examine the brain, spine, joints e.

The powerful magnetic field of the MR system can attract objects made from certain metals i. This can pose a possible risk to the patient or anyone in the object's "flight path.

As a patient, it is vital that you remove all metallic belongings in advance of an MRI examination, including external hearing aids, watches, jewelry, cell phones, and items of clothing that have metallic threads or fasteners.

Additionally, makeup, nail polish, or other cosmetics that may contain metallic particles should be removed if applied to the area of the body undergoing the MRI examination.

Various clothing items such as athletic wear e. These items can heat up and burn the patient during an MRI. Therefore, MRI facilities typically require patients to remove all potentially problematic clothing items prior to undergoing an MRI. Therefore, all MRI facilities have comprehensive screening procedures and protocols they use to identify any potential hazards.

When carefully followed, these steps ensure that the MRI technologist and radiologist know about the presence of any metallic objects so they can take precautions as needed. In some unusual cases, due to the presence of an unacceptable implant or device, the exam may have to be canceled.

For example, the MRI exam will not be performed if a ferromagnetic aneurysm clip is present because there is a risk of the clip moving and causing serious harm to the patient. Besides possible movement or dislodgement, certain medical implants can heat substantially during the MRI exam as a result of the radio waves i.

MRI-related heating may result in an injury to the patient. Therefore, as a patient, it is very important for you to inform the MRI technologist about any implant or other internal or external object that you may have prior to entering the MR scanner room.

The powerful magnetic field of the MR system may damage an external hearing aid or cause a heart pacemaker, electrical stimulator, or neurostimulator to malfunction or cause injury. If you have a bullet or any other metallic fragment in your body there is a potential risk that it could change position and possibly cause an injury.

In addition, a metallic implant or other object may cause signal loss or alter the MR images making it difficult for the radiologist to see the images correctly. This may be unavoidable, but if the radiologist knows about it, allowances can be made when obtaining and interpreting the MR images.

For some MRI exams, a contrast material known as a gadolinium contrast agent may be injected into a vein to help improve the information seen on the MR images. Unlike the contrast materials used in x-ray exams or computed tomography CT scans, a gadolinium contrast agent does not contain iodine and, therefore, rarely causes an allergic reaction or other problem.

If you are unsure about the presence of these conditions, please discuss these matters with the MRI technologist or radiologist prior to the MRI examination.

You will typically receive a gown to wear during your MRI examination. Before entering the MR system room, you will be asked a variety of questions i. Next, you will be instructed to remove all metallic objects from pockets and hair, as well as metallic jewelry. Additionally, any individual that may be present during your MRI will need to remove all metallic objects and fill out a screening form.

If you have questions or concerns, please discuss them with the MRI technologist or radiologist prior to the MRI exam.

As previously indicated, you will be asked to fill out a screening form asking about anything that might create a health risk or interfere with the MRI exam. Items that may create a health hazard or other problem during an MRI include:.

Important note: Some items, including newer cardiac pacemakers, ICDs, neurostimulation systems, cochlear implants, and medication pumps are acceptable for MRI. However, the MRI technologist and radiologist must know the exact type that you have in order to follow special procedures to ensure your safety.

Therefore, please provide the name of the device and manufacturer to the MRI technologist prior to the MRI exam. Items that need to be removed by patients and individuals before entering the MR system room include:.

Objects that may interfere with image quality if close to the area being scanned include:. The MRI examination is performed in a special room that houses the MR system or "scanner.

The typical scanner is open on each end, or at least two sides.

Most MRI incidents can be avoided. Regular MRI safety training is one our greatest weapons in preventing accidents.

Many MRI safety incidents happen when non-MRI personnel are trying to help with patient care. Others happen during medical emergencies codes when personnel are focused on resuscitating a patient and forget about the invisible danger of the magnetic field.

Unfortunately, even with an increased focus on safety, accidents in MRI departments still happen. Every year OHSU Diagnostic Imaging requires annual training for anyone who might enter an MRI environment.

Compass training will launch on July 1 and is assigned to OHSU employees by their manager. Those seeking MRI Safety approval need to complete two steps: answer questions in Enterprise Health followed by completing a Compass training module.

Typical approval turnaround time is business days with a minimum of 24 hours. This year we will have tables set up in the HRC lobby to pick up your badge stickers, which are required to enter the MRI department. This year we will also be holding an MRI open house for those that have completed their MRI Safety Training.

Badge sticker pick-up will also be available during our MRI Open house. Contact us if you have more questions regarding MRI Safety. Magnetic Resonance Imaging MRI is a noninvasive diagnostic exam that uses radio waves RF and a strong magnetic field to move the electrical components of our cells.

The MRI scanner is an extremely powerful magnet that attracts items with ferromagnetic substances such as iron, steel, cobalt, and nickel. Be aware that the magnetic field from the scanner, though powerful, cannot be seen or felt.

Only ferromagnetic substances can be pulled to the magnetic field, and the strength of the pull grows the closer they get to the center of the magnet. When a ferromagnetic object gets within the scanner's magnetic field and is pulled rapidly into the scanner, this is called the "missile effect.

It's important to remember that the MRI machine is always magnetized—it's always on. OHSU MRI is fully accredited, and our yearly training follows the guidelines put forth by our accrediting body, The American College of Radiology ACR. The ACR has also defined 4 safety zones around MRI units.

Each zone represents an increased level of magnetic field exposure and, as a result, increased safety risks. Zones 3 and 4 can only be accessed after training and permission is given. Many patients and employees have different and complex medical histories.

The most important thing is to screen patients and yourself. Many implanted and electronic medical devices have ferromagnetic material in them. OHSU has become the leader in the state of Oregon for scanning patients with implants. Active implants Pacemaker, VNS, DBS, Spinal Cord Stimulators, Pain pumps, Insulin pumps, implanted chemotherapy pumps, and loop recorders require very specific scanning parameters to minimize risk to the implant and the patient.

A specific type of active implant could have many manufacturers and multiple models, and each manufacturer and model could have different requirements for safe scanning.

All implants that have been approved for scanning are required to be tested in an MRI environment for heating, torque, and rotational translation, and the data is presented to the FDA for approval. Once the FDA approves an implant as safe or conditional, the FDA labeling for safe scanning of a device is then set.

So, the Implant review process always requires that each implant be reviewed individually.
