Experiment Label


NOTEIt's important that the MRI or PET operator uses use the experiment name Experiment Label as the Patient Name in the DICOM header during an MRI or PET session.

Please ensure the Experiment Label is entered correctly at all data entry occurences as a misspelled Experiment Label can have significant consequences throughout the Neuroinformatics Platform system.


The Experiment Label must be the Participant Label concatenated with the visit code, session code and modality code using underscores.

Ex. ABC01_CMH_00000001_02_SE03_MR

ExampleDefinititionRestrictions/RulesNotes
ABCProject Code3 Uppercase LettersChosen in coordination with KCNI admin. Preferably a project acronym. Cannot match existing project.
01Study Code2 DigitsTypically '01', unless describing divisions within a project
CMHSite Code3 Uppercase LettersMust be chosen from the Site Code List

02Visit Code2 DigitsIncrement each visit
SE03Session CodeSE followed by 2 DigitsIncement each session within a visit
MRModality Code2-4 Uppercase LettersMust be chosen from the Modality Code List


The Visit Code is 2 integers that represent the visit number. For example, 01 is first baseline visit, 02 is a follow-up visit, etc..

The Session Code is the letters 'SE' followed by 2 integers which distinguish different data capture sessions in a single visit. For example, if you are conducting an MRI experiment and you collect data before some intervention, the participant leaves the scanner for the intervention, then the participant returns to the scanner the session code should be incremented by 1. Notice the difference between visit and session where a visit denotes a participant coming to the institution for data acquisition where a session is denoted as a continuous acquisition of scans.

The Modality Code is 2 to 4 characters, denoting the modality with which the data was acquired. See the list of image modality codes below. For example, MR = Magnetic Resonance Imaging which includes fMRI, MRI, MRS etc.


Modality Codes

The Modality Code denotes the apparatus with which the imaging data was acquired and is appended to the end of the Experiment Label
