I'm happy to see that this article's progress towards GA status is being resumed; it is not at all far from arriving there. However, some issues remain unaddressed since 2017, as can be seen by comparing the open items in Talk:Magnetic resonance imaging/GA1 with the current state of the article.

In particular, there remain some "citation needed" tags from then, and some "page needed" tags which have also not been addressed in the intervening period; in addition, I've tagged an uncited paragraph in Angiography, and a claim in History, as also needing to be cited.

• @Chiswick Chap: added some references in the following, will work on the rest as well
  • Interventional MRI
  • Multinuclear imaging --Kostas20142 (talk) 17:50, 8 December 2019 (UTC)

Good stuff. No need to ping me, I'm watching. You should format the new refs like the old ones. Chiswick Chap (talk) 19:40, 8 December 2019 (UTC)

Glad to see the uncited issues have been resolved.

• • resolved safety, added to Multinuclear imaging

Please observe indenting and leave space before the next item. Safety was not fully resolved; I've formatted its refs, see previous remark, and added mention of projectile risk, which was mentioned on the GA1 page. In short, far more care is still required.

I notice some items are now marked as needing update.

Can't find any more --Kostas20142 (talk) 16:30, 16 January 2020 (UTC)

Yes, they've been fixed. Chiswick Chap (talk) 17:50, 16 January 2020 (UTC)

• regarding Usage by organ or system, would you be ok if I modified it as " MRI affects diagnosis and treatment in many specialties although the effect on improved health outcomes is uncertain disputed in certain fields. ", citing the one that is used for the lower back pain and maybe finding one more? --Kostas20142 (talk) 17:50, 8 December 2019 (UTC)

Should be fine, and yes, another example would be good. Chiswick Chap (talk) 19:40, 8 December 2019 (UTC)

Done the modification. Regarding the example, the one reference actually provides 2, but I can look for another as well.

That would be great.

"Non-medical use" still seems to me to be far too brief. In particular, something must be said about its use in biological research. For instance, Application of magnetic resonance imaging in zoology is a substantial area of application of MRI, leaving aside the protein-analysing capabilities of NMR which now seem to be out of scope given what is written in the lead, thankyou. You might also mention MRI in botany (whole plants). Perhaps you should also mention MRI in palaeontology (fossils).

Do you think that these applications should be within article's scope? --Kostas20142 (talk) 15:43, 8 January 2020 (UTC)

Yes absolutely. Chiswick Chap (talk) 17:32, 8 January 2020 (UTC)

I added these, you may wish to take a look. there might be a few more (notably assessing quality of food intended for human consumption however I feel it starts getting a bit out of scope). --Kostas20142 (talk) 23:28, 16 January 2020 (UTC)

That's great.

"History" too seems very insubstantial, given the quite decent History of magnetic resonance imaging which has plenty of citations, images, and detail. A rather better summary of that article is required here.

On it --Kostas20142 (talk) 15:54, 12 December 2019 (UTC)

The "Economics" section remains far too US-centric, and I mentioned back in 2017 that each price needs to be associated with a date, i.e. this cost $xxx in 2007 or whatever.

I cannot find any new reliable sources saying something in specific regarding MRI scanners cost _ however all provide a (relatively wide) range. would you like this to be added? --Kostas20142 (talk) 21:16, 7 January 2020 (UTC)

Well if the problem's unfixable it would be better to remove the old, unbalanced material, probably the entire section.

For now removed the whole section --Kostas20142 (talk) 14:16, 8 January 2020 (UTC)

Thanks.

Also from 2017 (let's check these are now resolved): --- I'm not convinced, either, that one-sentence sections in By organ or system are satisfactory. Suggest a little detail for Cardiovascular and Musculoskeletal to make them worthwhile sections.

I have added sokmething a few weeks ago, but it might require more. --Kostas20142 (talk) 16:25, 16 January 2020 (UTC)

Thanks.

--- The sudden dive into extreme technicality in the "Overview table" in Sequences is a bit uncomfortable. The material is repeated from the main article, MRI sequences, which isn't the right way to handle a 'main' link. I suggest we remove the table and write a paragraph or two with one or two images only (the most clearly distinct, perhaps) to explain what the idea of sequences is all about, with the best secondary sources.

I am not really sure it is actually possible to resolve this; I think the whole concept is a bit too technical itself and so most of the sources are. I could ask for help at the relevant WikiProject page though. Otherwise, would completely ommiting it and adding a "see also" work? (not a big fan of it though)--Kostas20142 (talk) 15:54, 12 December 2019 (UTC)

Yes, you can do that if all else fails. A link in the article body would be much better than a see also, however. Chiswick Chap (talk) 15:58, 12 December 2019 (UTC)

It doesn't really seem fixeable to me - I feel we either have to keep it as is or drop the table. But I actually think the table helps the reader get an idea. --Kostas20142 (talk) 18:54, 7 February 2020 (UTC)

OK, let's assume it can stay for now.

--- The 'Other specialized configurations' is similarly far more technical than the rest of the article, and very long. If it's the case that these are rather specialized and rare techniques, then they might go in a subsidiary list article and be summarized here with a 'main' link and a brief paragraph or two. If they're really rather important then they had better stay but be explained without too much techspeak (a specially juicy one is "heteronuclear magnetization transfer MRI that would image the high-gyromagnetic-ratio hydrogen nucleus instead of the low-gyromagnetic-ratio nucleus that is bonded to the hydrogen atom" but there are plenty of others).

This item has not been resolved really, but if we're talking about reaching a basic standard then at least this article "covers the main points" and is fully cited, which is good progress.

maybe we could remove this section and add it at see also? --Kostas20142 (talk) 21:25, 9 February 2020 (UTC)

I don't think that would make any sense - it would weaken the article, as molecular imaging is certainly a notable subtopic. Instead, we just need a citation for the first paragraph, surely not difficult. I've done that for you, it only took a moment to locate. Chiswick Chap (talk) 21:31, 9 February 2020 (UTC)

Some help with this and only would be appreciated. But I ran a random check because something didn't fit, and it seems we have a clear-cut copyvio so it will require that the section is re-written. --Kostas20142 (talk) 21:47, 9 February 2020 (UTC)

--- These changes will dictate some rewriting of the lead section, which should simply and clearly summarize the text.

When all the above items are resolved, I will re-review the article to see if it 'works' as a piece in its new form. I will also need to do some verification and image checks. Chiswick Chap (talk) 09:40, 9 December 2019 (UTC)

Well, this has taken a long time and progress has been slow; not all items have been actioned, and formatting leaves something to be desired. However, if we ask ourselves whether the core requirements of GA have been met, the answer is yes, it's fairly readable, not plagiarised, fully cited, illustrated, covers the main points and doesn't look a total disaster. I will therefore pass it now, but will note that GA nominators should make themselves reasonably available to fix reviewers' comments promptly. I do hope that you are pleased with the result and will take the time to review one or two articles from the ever-lengthening GAN queue. Chiswick Chap (talk) 21:49, 9 February 2020 (UTC)
