Turku PET Centre neuroscientists and Human Emotion Systems Laboratory are happy to announce that the third edition of our PET-MRI neuroimaging course will be held on September 19th -21st 2022. This course will give a hands-on overview on the basic brain imaging analysis techniques applicable to PET as well as structural and functional MRI data. The course is aimed at PhD students, post-docs, and scientists working on medical, cognitive, and computational neuroimaging. Masters’ students are also welcome. Participants are assumed to have rudimentary knowledge of human brain anatomy and function, neuroimaging, and working with PET and MRI data, but this is not strictly necessary. After the course, the participants should be able to independently process and analyse the data that has been retrieved from PET camera / MRI scanner. Analytic pipeline will focus on the PET Centre brain data analysis framework but can be adapted to any analysis platform.
Registering and ECTS credits
The course is arranged as a part of the curriculum for master’s degree in Psychology at the University of Turku with course code PSYK8965 and completing the lectures and examination totals 5 ECTS for our own MA / PhD students. If you are not studying at University of Turku, we can however give certificate (on request) of participation stating that the attending the lectures on the course cover approximately 2 ECTS credits. Please contact prof. Lauri Nummenmaa for details.
Registration for the course has been closed. Next course will be organised in September 2023!
Practical information
All lectures will be held on site in University of Turku lecture hall PUB2 (Publicum building). Lectures will also be streamed live using Echo360 platform. It is recommended that you use a desktop computer or laptop (rather than tablet computer) for viewing the lectures so you to can follow the online and hands-on demonstrations. Lecture duration is ~45 minutes +10 minutes for questions. When logging on to Echo360, select the the currently active class to view the live stream. You need to manually advance to the next class when the previous one ends. Lectures will be stored permanently and they can also be viewed afterwards, the recordings are available almost immediately after the live stream ends.
The live streams and records lectures are still available on Echo360 platform via this link
Asking questions remotely
Echo360 discussion forum does not work for those who do not have an account at our university thus we have set up a Discord channel for questions & answers. Because the lectures will be recorded, the speakers will discuss the questions and comments after rather than during each lecture. Our team will follow the channel constantly and we will do our best to answer all the either immediately or after the lectures.
Questions can be asked remotely with Discord using this channel
Schedule
The schedule below is in Helsinki time (EEST), which is UTC+3. Changes are still possible so please re-check the schedule on the webpage and on Echo360 before the course starts. Slides to the lectures (PDF) will be provided on this page, use the link above for accessing the recorded lectures.

Data packages used in the course
PET dataset
This is the full NRM dataset with the LondonPride ligand, kindly provided by the King’s College London PET team. The dataset consists of two PET scans (and associated files) per subject: a baseline scan and a displacement scan. The dataset is available from NITRC via this link.
Pet dataset for MAGIA
This is a subset of the LondonPride dataset for learning MAGIA, the in-house data processing pipeline hosted by Turku PET Centre. Download the dataset from this link.
fMRI dataset
This small dataset from Turku PET Centre contains EPI and T1 data from an experiment, where the subjects viewed pictures with varying content. Download dataset from this link.
LINKS TO SOFTWARE PAGES
MAGIA toolbox
MAGIA is a comprehensive brain-PET modelling suite, which has been optimised for large-scale brain-PET analysis.
