ELSC Neuroimaging Unit (ENU)

Information For Users

Conducting MRI Research

Researchers and labs that are interested in conducting research with ELSC’s Neuroimaging Unit (ENU), must register with us to become  users.

Each lab is required to choose one member as their 'Lab Coordinator'. This person is in charge of submitting requests and must be familiar with all the following:

All researchers must complete a GCP Online Course. Once in the CITI Program site, you should click on 'Register', choose 'Participating Institutions' and select or enter 'Hebrew University'. Once you complete the creation ofyour  personal account you will be eligible to take the GCP course free of charge. Returning users can simply login.

All reserchers must conduct their research according to these Helsinki regulation & updates

Procedure to become a User:

                                         Step 1 → Helsinki Approval    Step 2 → Becoming an ENU User

Step 1. Submit a New Helsinki Request:

  1. Fill an 'ENU protocol request summary' and an 'ENU protocol format' and then send them to the ENU committee for approval. The ENU committee meets once a mouth. 
  2. Once approved by the ENU committee, schedule a meeting with the Helsinki Unit Coordinator to enter your request through the "Matarot" software. 
  3. You will then receive forms that need to be signed by the Lab staff.
  4. Submit the signed forms to the Unit Coordinator for further signatures.
  5. Once all the signatures are received, then the request will be submitted for approval to the Hadassah Helsinki committee. 
  6. It is the Lab coordinator’s responsibility to check the status of their request with the ENU Helsinki Coordinator.

Step 2. Becoming an ENU User

Once the request is approved by the Hadassah Helsinki Committee, the research laboratory will be permitted to complete the process to become an ENU user. 

The Lab Coordinator will contact (mail or phone) the ENU office in order to: 

  1. Open an account in the ENU Reservation System. The lab will receive a user name and a temporary password.
  2. Verify that the researcher's name is regeistered on the lab's Helsinki approval (i.e. the name of the person running the experiment).
  3. Make sure the researcher completes the ENU Safety Training Course and reads the ENU working guidelines and safety policy   (File in English)
  4. Only after completing steps 1-3 will a researcher be alowed to use the MRI and be registered as an ENU Operator!
  5. In addition, before using the MRI for the first time, the lab coordinator must meet with the ENU Director (and sometimes the unit's physicist as well) in order to build/approve the scanning sequences. 
  6. The Lab Coordinator is also responsible for depositing money (tofes 29 or directly to ENU Budget), for MRI use.
  7. Finally, in order to receive all ENU updates (e.g. canceled scanning slots), all ENU Users and Operators , must register to the enu-ops mailing list.

Steps for Changing an approved Helsinki:

Labs who wish to make changes to their approved Helsinki (ex. add members or change protocol, etc.), must do the following:

1. The Lab’s Helsinki coordinator must schedule a meeting with the ENU Helsinki coordinator, to make the requested changes via the ‘Matarot’ software.

2. The ENU Helsinki coordinator is then responsible to get the necessary signatures from Hadassah and submit it to the Hadassah Helsinki committee.  (Changes to an Approved Helsinki are done on a monthly basis).

All requests and inquiries should be submitted through the Helsinki unit coordinator, Lee Ashkenazi (lee.ash@mail.huji.ac.il)

For your convenience, we advise you to follow these submission deadlines:

Initial submission to ENU Helsinki coordinator should be done 6 weeks before the Hadassah Helsinki committee dates. This procedure includes corrections and signatures. 

Dates of Helsinki committee in Hadassah: 5.3.18, 16.4.18, 7.5.18 ,29.5.18, 11.6.18, 26.6.18, 9.7.18, 24.7.18, 6.8.18, 21.8.18, 4.9.18, 8.10.18, 23.10.18, 5.11.18, 20.11.18, 3.12.18, 18.12.18.

Working guidelines & safety:

Scanning people with tattoos

Scanning people with tattoos has been approved for ENU, under certain limitations:

  • People with permanent makeup, tattoos on the head, neck, or face, or people with large tattoos (over 10% of the skin) cannot be scanned.

Extra care should be taken when scanning people with tattoos:

  • The participant will declare the existence of a tattoo, its size, location on body, and the place of making the tattoos in writing as part of the metal questionnaire.
  • In addition to written information, the participant will report orally to the RT about any tattoos or permanent makeup. The location, size and color of the tattoo must be reported as well.
  • The participant will be given all information about the potential risks associated with scanning tattoos. This information will be given both orally and as part of the informed consent form that was approved by the Helsinki committee.
  • The participant will be instructed to immediately report any heat/pain or abnormal sensation in the area of the tattoo. The participant should explicitly be told that they should press the stress button (and thus stop the exam) at any time during the exam if they fell heat in the area of the tattoo.
  • Subjects with tattoo will be monitored closely, while maintaining auditory and/or visual contact throughout the exam.

Even when all limitation are followed, the radiology technician may decide not to scan a potential participant with a tattoo.

The inclusion of participants with tattoos in the research must be confirmed for each research protocol (Helsinki) separately, and be explicitly included in the informed consent form of that research!
