Safety Policy

The full CNI safe operating procedures and policy document is available as a pdf document. The CNI Subject Screening form is available as a pdf document.

The Stanford Center for Cognitive and Neurobiological Imaging (CNI) Committee uses the internationally accepted recommendations from the American College of Radiology to establish Research MR Safety Policies and Procedures. The CNI staff will ensure that all users of the CNI research MR facilities will be well acquainted with these policies and procedures to ensure a safe standard of practice.

Follow this Getting Started link if you are new to the CNI and would like to learn about the basic facilities, and how to get access and training in using the CNI facilities.


New Safety Updates will be posted here.

Safety Alert - January 11, 2012. Potential burn issues with "antimicrobial" clothing.

There is a recent article describing a sedated subject who received 2nd degree burns during an MRI exam. It appears the burns were caused by her wearing an "antimicrobial" shirt which contained invisible silver-embedded microfibers in the Coolmax/Lycra fabric. The presence of these silver fibers was not indicated on any labels on the shirt. The authors point out these antimicrobial fabrics are becoming more popular, especially in athletic wear, socks, and bras.

We currently recommend that during the screening process, study participants be instructed to wear 100% cotton or wool clothing (or in the words of the article, "other safe non-trade name fabrics"). As of now we are not requiring scan participants to wear scrubs.

We currently also recommend that participants be instructed to inform the scanner operator if they feel any uncomfortable local heating sensations during a scan.

Safety Alert - May 22, 2012 New Magnetic Nail Polish could be a safety issue

This is an information from Melissa Henry, who has come across this with her participants -

"We've been scanning teen girls and there seems to be a new nail polish on the market that is advertised as magnetic, I'm not sure if you've heard of it. This may or may not be a hazard but we have begun advising all participants to refrain from using such products on the day of their scan. Just a note on crazy trends that may pose a safety risk."

We currently have nail polish remover available at CNI.

Safety Alert - April 8, 2013 Concerns about colored contact lenses -

Circle contact lenses, also known as color contact lenses and big eye contact lenses, are a type of cosmetic contact lens. It is not generally known that a circle contact lens usually contains iron oxide and other metals, which means their use during magnetic resonance imaging (MRI) is a potential hazard.Case presentation We present a rare case of incidental discovery of circle contact lenses by MRI and MRI images of circle lenses in vitro.

Conclusions: Circle contact lenses usually contain iron oxide, which is a known source of susceptibility artifact on MRI.

Not only radiologists and radiographers but also referring physicians should be familiar with the imaging findings and potential risk of scanning circle contact lenses by MRI.

Safety Alert - June 30, 2014 Concerns about Yoga Pants

This is related to the safety item above dated January 12, 2012.

The comfortable, stretch, barely-there yoga pants all girls know and love have metal mesh built into the fabric, which is what helps keep the body dry during exercise. But it appears that a (seemingly) ordinary pair of yoga pants could end up causing burns in an MRI.

We currently recommend that during the screening process, study participants be instructed to wear 100% cotton or wool clothing (or in the words of the article, "other safe non-trade name fabrics"). As of now we are not requiring scan participants to wear scrubs.

We currently also recommend that participants be instructed to inform the scanner operator if they feel any uncomfortable local heating sensations during a scan.

Intrauterine contraceptive devices (IUD) are in general MR safe, however we currently do not recommend scanning participants with copper IUDs for research projects. Users can refer to this webpage for more information.

Facility and Resources

We think you will find the text for preparing Facilities and Resources useful when preparing sections of NIH or other grants.

Location, Parking Information, Transportation, and Directions

Location The Stanford Center for Cognitive and Neurobiological Imaging (CNI) is located in the basement of the Department of Psychology at Stanford University. The official address of the building is Jordan Hall, Building 420, Stanford, CA 94305. A map of building and parking locations is here and described additionally below.

Parking Information for Volunteers/Participants - "Q" parking passes are available for study participants. Please see the Facility Manager, Laima Baltusis to obtain the these parking passes. Please note that as of June 23, 2014, due to the Old Chemistry construction project, the "Q" parking spaces have been relocated to the corner of Roth Way and Palm Drive and are no longer on Lomita Drive across from the Old Chemistry building. There are now three Q-spaces reserved for study participants. Please fill out or have your participant fill out the 'Q' permit with the date of the appointment and leave it on the dash.

Campus Map
Q parking space

Campus directions are available as a pdf document.

If all "Q" spaces and the adjacent metered spaces are taken, your participant may park in the visitor spaces on Lomita Dr. by the Cantor Center for the Arts. Note, however, that these are pay spaces and that he/she will need to pay at one of the nearby parking kiosks (no maximum time limit). Payment is by debit/credit cards.

Additionally, your participant may also park in the visitor spaces on Palm Dr. along the Oval. Note, however, that these are also pay spaces and that he/she will need to feed the meter with coins (maximum two hours).

Transportation to and from Stanford Hospital to CNI - Study participants who are coming from the hospital can use the hospital tram ("golf cart" shuttle) to go between the hospital and CNI. Arrangements for pickup and drop off can be made be calling the hospital Patient Guest Services at 650 498 3333. The service is normally available between 7AM and 7PM. Off hour arrangements can be made in advance.

Incidental Findings

On occasion brain images collected during the course of a study may show a potential abnormality. In that case we refer the images to an appropriately qualified individual, designated by the CNI Board, for further review. The reviewer will determine if the potential abnormality merits further investigation and will inform the PI of the action to be taken.

Graduate students, RAs, and postdoctoral fellows should not be responsible for contacting a subject about the review. The PI should generally not attempt to explain to the subject the potential finding or offer medical advice on how to proceed. The report is not an official clinical diagnosis because the research protocol does not qualify as a clinical diagnostic scan. Further, the scans should not be offered to subjects and/or their physicians. However, an individual subject may be entitled to his or her data upon request under the terms specified in the consent form.

The CNI operations team refers images of potential abnormalities to the designated reviewer. The CNI promptly provides a DVD with the scans in question or in another way makes the images available to the reviewer to be read "as is". Subjects are informed of this practice in the research consent form under the section titled "Incidental Findings". The current step-by-step process for incidental findings is:

  1. The investigator notifies the CNI facility manager or research director of a potential incidental finding, providing the exam date, exam number, and the series and image number numbers that are of concern. The exam may already have the subject's name, sex, and date of birth. If this information is missing in the exam please provide it to the facility manager.
  2. The facility manager delivers the images to the reviewer.
  3. The reviewer reads the images and sends a report to the CNI staff and the PI, including a recommendation to the PI regarding whether the subject should be contacted.
  4. If communication to the subject is called for, the PI on the study contacts the subject relaying the appropriate information, including the non-clinical/diagnostic nature of the scan and the review.
  5. Documentation of the review is kept by the facility manager in the corresponding IRB folder.
  6. The PI should document in the subject's study record when and how the information is communicated to the subject, any questions the subject had, and any other relevant information.

Contact Laima Baltusis, the facility manager, for help with this process.

Non-human research

Volume rendering of three species: Malus domestica, Citrus Sinensis, and Musa acuminata. (3D CUBE T2 scan from the CNI 3T GE MR750.)

The CNI is intended primarily for studies of human subjects. Permission to use the scanner for non-human animal research must be approved by Research Director on a case-by-case basis. Please contact the Facility Manager (Laima Baltusis, laimab@stanford.edu) or the Research Director (Robert Dougherty, bobd@stanford.edu) for all research, IRB concerns and questions.

During training, users often hone their safety skills on non-human material. Fruits and vegetables may be scanned without prior approval ;).

Communications

This wiki is the primary method for the staff CNI to disseminate knowledge about CNI operations, equipment, and scan protocols. The CNI staff also holds semi-regular seminars.
