Good work already! I've added a "Choice of modality" section at [[MRI of the liver]]. I also added such a template at [[Steatosis]], in order to add the same information to the ultrasound article there. I also added you as an author of that article, and I hope that is alright with you.
However, I reinserted the abdomen image on the main page, since I think it provides a better overview of the anatomy than a list. Also, I think a list of diseases (even the most important ones) will eventually be too comprehensive to be fitted into the main page. Thus, I think they should stay at the articles concerning specific organs, see [[Radlines:Editorial_guidelines#Modality.2BLocation_articles|Editorial guidelines: Modality+Location articles]]. Still, I agree [[abdominal wall]] should still be mentioned there, since it is difficult to appropriately include in the image. Also, I was able to expand the [[Abdomen and pelvis]] with the [[Inguinal]] region, and I intend to include it in the next update of that {{tl|Abdomen and pelvis locations}} image. I'm also somewhat against adding links to diseases that yet lack an article. I added to those editorial guidelines that "For any entry that does not yet have its own article, preferably only list it if you intend to write that article yourself in a near future." I also copied your "emergencies" section to the top of [[Abdomen and pelvis]]. I hope you're not taken aback by these edits and comments. I think your edits are highly beneficial both for the information itself, and for reflection on how to continue building this project.
