15th of June 2022: Abstract submission for the International Magnetic Resonance Spectroscopy Workshop “MRS 2022: Overcoming the Barriers to Clinical Use”

Dear MR Spectroscopists, Dear colleagues, Dear friends,

:alarm_clock: :mega: Time is ticking
The deadline for the abstract submission for the International Magnetic Resonance Spectroscopy Workshop “MRS 2022: Overcoming the Barriers to Clinical Use” is *15th of June 2022.

We look forward in receiving your contributions, work in progress, independently of their past submissions. Homepage - MRS Workshop 2022 (cibm.ch)

20 abstracts will be selected for oral presentations and the rest for poster presentations. Travel awards will be offered. We are in discussions for organizing a Special Issue.

We also had different questions for the abstract format: Your Abstract, Your Way :blush:, just fit all the abstract in 1 page (Letter or A4)

  • 1 page A4/Letter in PDF format with minimum font size of 10pt including title, co-authors, affiliations, figures and references. Nice figures are always welcomed to highlight your amazing data :slight_smile:

  • Please send your abstract by email to cristina.cudalbu@epfl.ch and jwijnen@umcutrecht.nl with “MRS workshop 2022 abstract submission” in the title

For PhD students we have several “Meet the experts” sessions – please contact dunja.simicic@epfl.ch if you wish to help with the organization, have new ideas and wishes.

Hotels have been preserved at lower rates, but some will be released as end of May, Don’t miss out and re serve today all details are provided on our web page, the reservation code works only by email ! with cancelation policy .
