NeuroPoly student feedback: Thomas Dagonneau

[tomDag25]

This issue is the global feedback for the mooc from Thomas Dagonneau. Disclaimer : I'm not a very good english speaker so I might see some typo where there are not or miss some.

Feedback for the ReadMe page :

• in 1.1 : maybe add (mOOC) after mini Open Online Course
• feels confusing to speak from a book in 1.2 section when you didn't mention anything about a book previously
• typo in 1.2 : Quantitative MRI (qMRI) aims to promises precise and reproducible measurements of tissue properties using MRI.
• typo in 1.3 : Leveraging the NeuroLibre platform, readers can access fully reproduce the material in this book and allows them to engage with real qMRI data through their web browser.
• typo in 1.3 space after the point : their web browser.This

Global feedback : Good first page : defines what is a mooc and the goal of the mooc

Feedback for Introduction to qMRI -> Basics of MRI and qMRI :

• in the See also : maybe put the name of the article instead of the year ? At first I didn't get that it was a link to the article and I thought the only link was to Nishimura wikipedia page

Global feedback : Clear

Tagging @agahkarakuzu as chapter 1 was from his thesis I believe

Feedback for Introduction to qMRI -> The million dollar question:

• not sure if that's the goal but in 1.1 the MR acronym has not the same feature as MRI to explain its signification
• typo 1.1 : sug- gests (maybe it's normal I don't know much about written reports)
• Fig1 : would be clearer and easier to read if the conventional MRI was on the right side of the figure since you speak about it before. Else you have to read the figure in the opposite direction to the one suggested by the text. (Else the figure's content is good)
• typo in 1.1 : an- other

Global feedback : Loved the bean russian roulette example. The historical aspect is very interesting !

Feedback for Introduction to qMRI -> A pictorial and historic journey into how MRI works

• the figure numbers don't seem to be making reference to any figure in the section
• typo in 1.1.1 : However, in reality, we don’t have access to observe NMR effects at such a fine-grained level
• 1.1.1 : quantum-jitters -> I don't know what it is so maybe defining it or putting a link to the wikipedia would be great (don't know if it was planned since there is no link in this page)
• 1.1.1 : Schrödinger’s cat -> put the wikipedia link ? Don't know how obvious this illustration is
• FIg5 : maybe put it after the text citing it. When you read the page you don't really understand where it's coming from before the text about Bloch

Global feedback : Good ! In the version I reviewed most links where missing and also references but I think it's normal

[tomDag25]

Feedback for Introduction to qMRI -> Measuring and encoding the MRI signal

• there is no under-title like in other sections
• in 1.1 I feel like the reader could benefit from seeing the new equation after removing the components = 0 : In this case, the last two terms of the equation vanish, leaving the precessional component of the equation.
• numbers of cited equations don't refer to the numbers of the equations
• 1.2 : The analogy with the defibrillator is not presented the same way as the analogy with beans and dating (in a square highlighted)
• Fig4 : I know what you are talking about so I get it but maybe to emphasise what a gradient is you could put a graph under the MRI scanner showing how the value evolves according to z for example ?
• typo in 1.4 : ob- servations

Global feedback : Good ! In the version I reviewed most links where missing and also references but I think it's normal

[tomDag25]

Feedback for Introduction to qMRI -> Two MRI sequences and two qMRI measurements

• I feel like a bit of explanation for the difference between T2 and T2* could be appreciated. For now there is only : T2∗ – the effective T2
• typo at the end : con- ventional

Global feedback : Good, and I validate both musical bands !

[tomDag25]

Feedback for Introduction to qMRI -> Will qMRI take over the world?

• the figure numbers don't seem to be making reference to any figure in the section
• Fig1 : very nice Fig but I don't find it easy to understand
• typo in 1.1 : Figure 2.23 shows that all

qMRI methods share a common methodolog

• typo in 1.1 : chal- lenging
• 1.2 is just a title ?

Global feedback : Good, 1.2 is missing there is only the title.

Feedback for T1 Mapping -> Inversion recovery -> Introduction

• typo space after the point : inversion recoverytechnique
• the cited figures don't refer to existing figures
• change in the way to count figure between the Introduction to qMRI chapter and this one (figure 1 vs figure 2.1)

Global feedback : Good

[tomDag25]

Feedback for T1 Mapping -> Inversion recovery -> Signal Modelling

• typo : 5_T_1 (2 times)
• Fig2.3 : maybe choose a default value of T1 so that when you load the page there is a difference between the two curves ?

Global feedback : Good

[tomDag25]

Feedback for T1 Mapping -> Inversion recovery -> Data Fitting

• typo : 5_T_1, 1.5_T_1
• only paper without a link : Barral et al. 2010

Global feedback : Good

[tomDag25]

Feedback for T1 Mapping -> Inversion recovery -> Benefits and Pitfalls

• References formating changed : green arrow

Global feedback : Good
