And the article on Obstetric ultrasonography contains an image of an obstetric ultrasound This isnt the article on obstetric ultrasonography A couple of other articles use the cartoons as well some but not all in contexts I think are unnecessary but guess what Its possible to stay on topic The images are used to prejudice people in favor of one particular choice They dont contribute anything essential to the article because people can click links if they want to know what an ultrasound looks like There is no reason to include them
